The intensity of the fields generated by fixed transmitters, determined by local electromagnetic tests(3) must be lower than the level of compliance for each frequency range(4). There may be interference near the equipment marked with the following symbol: NONOTE 1 For 80 MHz and 800 MHz, the greater frequency range applies. NOTE 2 This guide may not apply in all situations. The electromagnetic propagation is affected by absorption and reflexion from structures, objects and individuals. Technical specifications | GraphNet advance neo ts 2. 9 (1) ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40.66 MHz to 40.70 MHz. (2) The levels of compliance in ISM frequency bands between 150 kHz and 80 MHz and in the 80 MHz and 2.5 GHz frequency range have been established to reduce the possibility that a portable/mobile communications device may cause interference if inadvertently introduced into the patient’s area. For this reason, an additional factor of 10/3 has been included in the formula used to calculate the recommended separation distance for transmitters in those frequency ranges. (3) The field intensities of fixed transmitters, such as radio telephone (portable or wireless) base stations and land mobile radios, HAM radios, AM and FM and TV broadcasts cannot be precisely predicted theoretically. To find the value of the electromagnetic environment generated by fixed RF transmitters, an onsite test must be conducted. If the measurement of the field intensity in the location where GraphNet-advance is being used exceeds the above applicable RF compliance limits, GraphNet-advance must be evaluated to make sure that it can operate normally. If abnormal performance is observed, it may be necessary to take additional measures, such as reorienting or relocating the equipment. (4) In the 150 kHz and 80 MHz frequency range, the field intensity should be less than 10 V/m. 2.1.11.4 | Manufacturer’s statement: Separation distances Table 2.1-14 Recommended separation distances between the respirator and mobile/portable communication equipment GraphNet advance is intended to be used in an electromagnetic environment in which radiated RF perturbances are controlled.

NOTE 1 For 80 MHz and 800 MHz, apply the separation distance for the larger frequency range. NOTE 2 ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40.66 MHz to 40.70 MHz. NOTE 3 An additional 10/3 factor has been included in the formula used to calculate the separation distance for transmitters that operate in the ISM frequency band between 150 kHz and 80 MHz and in the frequency range of 80 MHz to 2.5 GHz to reduce the likelihood that mobile and/or portable communication equipment can cause interference if they are inadvertently introduced in patient areas. NOTE 4 These guides may not apply in all situations. The electromagnetic propagation is affected by absorption and reflexion from structures, objects and individuals. 2. 10 Technical specifications | GraphNet advance neo ts 2.1.12 | Basic Respirator Operation GraphNet advance has a microprocessed control system that coordinates the tasks that arise from programming the equipment. All the actions performed by the respirator are commanded by this system. The flow of gas received by the patient is administered by two proportional valves, one for air, the other for oxygen. The valves operate simultaneously, providing the appropriate oxygen concentration and the necessary flow wave characteristics. The exhalation valve is controlled by two attached valves. One of them, with ON/ OFF features, tells it to open or close, which determines the end and the beginning of the inhalation phase, respectively. The other valve is proportional, and is in charge of regulating the PEEP level when it is configured. The microprocessor is re-fed with signals that come from the sensor system in the respirator. This makes it possible to control and adjust the configured ventilatory program. Airway pressure is measured with a transducer related to a sensor on the end of the patient circuit (exhalation set) or, as an option, on the connection to the patient for the NEO-INF category (on the proximal pneumotacograph). The signal that comes from this transducer is also used to trigger inhalations when the pressure sensitivity, respiration cycling, alarm levels and others, are enabled. The proximal pressure is measured with a transducer next to the patient output. The most relevant task of this item is pressure control in pressure controlled or support pressure mode respirations. Flow information is obtained through two differential pressure transducers related to the internal output pneumotacograph and the exhalation (distal or proximal) pneumotacographs. The internal pneumotacograph (Silverman mesh type) makes it possible to control the flows and volumes driven by the respirator in the inhalation phase. The exhaled flows are measured through the exhalation (distal and, as an option, proximal) pneumotacographs. The equipment has a system of valves that allows for a communication route between the pressure transducers and the ambient pressure. This way, the transducers can be zeroed. Simultaneously, a flow of air is pushed through to purge the exhalation pneumotacograph lines and prevent water and moisture from settling on the measurement elements. 2.1.13 | Safety Mechanisms GraphNet advance has a full safety system that includes the operational system that controls the microprocessor and various components that act independently from them. • WATCHDOG: This is a system that monitors the operation of the electronic circuit and exercises control independently from its integrity. When it detects an anomaly in the operation of the respirator, it allows it to discontinue and activates an emergency ventilation mode, the Emergency Ventilation. The Watchdog can activate the Emergency Ventilation in two different situations: - After 30 s have elapsed since the respirator has been turned on, without selecting a patient category, on the first initial calibration screen. - When the microprocessor loses control of the program sequence regulating ventilation. • EMERGENCY VENTILATION: the Emergency Ventilation is a safety mechanism Technical specifications | GraphNet advance neo ts 2. 11 that is activated in extreme conditions to provide the patient with temporary ventilation until measures can be taken to replace the respirator with an alternative ventilation mechanism. It is not a valid operational mode. The Emergency Ventilation allows delivery of respirations with characteristics that are similar to controlled pressure (PCV). During this event, only the peak pressure and the respiratory frequency are monitored. The predetermined values of the ventilation parameters are indicated in Table 2.1-15. The alarm limits are not enabled for modification. The active alarms are Maximum and minimum pressure, and maximum respiratory frequency, whose limits appear on screen. The only enabled complementary function is Manual Insp. Table 2.1-15 Ventilation parameters in Emergency Ventilation Parameter Initial value Range Observations Controlled pressure (PCV) 10 cmH2O 2 – 30 cmH2O The pressure is limited by maximum alarm pressure at 30 cmH2O. This limit cannot be changed. Ti (inhalation time) 0.70 s 0.10 – 3.00 s The inhalation time can be limited by the frequency value. Resp. frequency 20 rpm 1 – 100 rpm The frequency can be limited by the inhalation time. Inh. Sensitivity -2 cmH2O -0.5 – 20 cmH2O O2 Concentration 50 - Same value as in PCV mode Same range as in PCV mode Upload time Flow sensitivity not enabled. This parameter cannot be modified. WARNING • If the Emergency Ventilation is activated, provide the patient with an alternative ventilation mechanism and find out the cause of this event. If it has been activated because of a delay in the acceptance of the first initial calibration screen, restart the equipment to ventilate the patient. • SAFETY VALVE: it is located immediately before the patient output. It opens when the pressure in the patient circuit reaches a value of 120 ± 5 cmH2O. The mixture of gases goes to an internal collector and is expelled. • INHALATION RELEASE VALVE (ANTI-ASPHYXIATION): this valve makes it possible to bring ambient air to the patient when the equipment is off or when the respirator is not in operation. • OPERATIONAL GAS RELEASE: the gases that can seep into the equipment are recovered in a common collector and expelled. • LACK OF COMPRESSED AIR PRESSURE: compressed air is used as a pneumatic circuit command gas. When it is missing, it can be replaced with oxygen. In addition, when the equipment detects a lack of air, it automatically switches to a 100% O2 concentration. 2. 12 Technical specifications | GraphNet advance neo ts • LACK OF OXYGEN PRESSURE: in this case, air replaces oxygen and the respirations are delivered with a 21% O2 concentration. • AUTOMATIC ZERO: every 10 minutes or when the operator activates it (by pressing [Ctrl] + [Ctrl]) all pressure sensors are zeroed. This restarts the readings, preventing possible offset errors in the measured pressures. During the first few minutes of ventilation, the respirator can zero faster than indicated. For each zeroing, a message appears on the Icon and message bar indicating that this process is in progress. • CIRCUIT PURGE: to prevent obstructions and moisture from moving into the pressure sensors, air is injected through the patient circuit while the pressure sensors are being zeroed. • ALARM SYSTEM: GraphNet-advance has an alarm system to warn of situations that involve some degree of risk to the patient or to the equipment itself. Some make it possible to keep the condition from which it originated from continuing, others simply trigger signals to report its presence. For further information about how the alarm system works, see the Alarms chapter. • PARAMETER ADJUSTMENT: to avoid unnoticed parameter changes, it is necessary to execute sequences established on the respirator controls. This way, pressing a single key or the dial does not result in changes being entered.

The intensity of the fields generated by fixed transmitters, determined by local electromagnetic tests(3) must be lower than the level of compliance for each frequency range(4). There may be interference near the equipment marked with the following symbol: Technical specifications | GraphNet advance neo ts 2. 21 NOTE 1 For 80 MHz and 800 MHz, the greater frequency range applies. NOTE 2 This guide may not apply in all situations. The electromagnetic propagation is affected by absorption and reflexion from structures, objects and individuals. (1) ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40.66 MHz to 40.70 MHz. (2) The levels of compliance in ISM frequency bands between 150 kHz and 80 MHz and in the 80 MHz and 2.5 GHz frequency range have been established to reduce the possibility that a portable/mobile communications device may cause interference if inadvertently introduced into the patient’s area. For this reason, an additional factor of 10/3 has been included in the formula used to calculate the recommended separation distance for transmitters in those frequency ranges. (3) The field intensities of fixed transmitters, such as radio telephone (portable or wireless) base stations and land mobile radios, HAM radios, AM and FM and TV broadcasts cannot be precisely predicted theoretically. To find the value of the electromagnetic environment generated by fixed RF transmitters, an onsite test must be conducted. If the measurement of the field intensity in the location where GraphNet-neo is being used exceeds the above applicable RF compliance limits, GraphNet neo must be evaluated to make sure that it can operate normally. If abnormal performance is observed, it may be necessary to take additional measures, such as reorienting or relocating the equipment. (4) In the 150 kHz and 80 MHz frequency range, the field intensity should be less than 10 V/m. 2.2.11.4 | Manufacturer’s statement: Separation distances Table 2.2-14 Recommended separation distances between the respirator and mobile/portable communication equipment GraphNet neo is intended to be used in an electromagnetic environment where radiated RF perturbances are controlled.

NOTE 1 For 80 MHz and 800 MHz, apply the separation distance for the larger frequency range. NOTE 2 ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40.66 MHz to 40.70 MHz. NOTE 3 An additional 10/3 factor has been included in the formula used to calculate the separation distance for transmitters that operate in the ISM frequency band between 150 kHz and 80 MHz and in the frequency range of 80 MHz to 2.5 GHz to reduce the likelihood that mobile and/or portable communication equipment can cause interference if they are inadvertently introduced in patient areas. NOTE 4 These guides may not apply in all situations. The electromagnetic propagation is affected by absorption and reflexion from structures, objects and individuals. 2. 22 Technical specifications | GraphNet advance neo ts 2.2.12 | Basic Respirator Operation GraphNet neo has a microprocessed control system that coordinates the tasks that arise from programming the equipment. All the actions performed by the respirator are commanded by this system. The flow of gas received by the patient is administered by two proportional valves, one for air, the other for oxygen. The valves operate simultaneously, providing the appropriate oxygen concentration and the necessary flow wave characteristics. The exhalation valve is controlled by two attached valves. One of them, with ON/ OFF features, tells it to open or close, which determines the end and the beginning of the inhalation phase, respectively. The other valve is proportional, and is in charge of regulating the PEEP level when it is configured. The microprocessor is re-fed with signals that come from the sensor system in the respirator. This makes it possible to control and adjust the configured ventilatory program. Airway pressure is measured with a transducer related to a sensor on the end of the patient circuit (distal pneumotacograph) or on the connection to the patient (proximal pneumotacograph). The signal that comes from this transducer is also used to trigger inhalations when the pressure sensitivity, respiration cycling, alarm levels and others, are enabled. The proximal pressure is measured with a transducer next to the patient output. The most relevant task of this item is pressure control in pressure controlled or support pressure mode respirations. Flow information is obtained through two differential pressure transducers related to the internal output pneumotacograph and the exhalation (distal or proximal) pneumotacographs. The internal pneumotacograph (Silverman mesh type) makes it possible to control the flows and volumes driven by the respirator in the inhalation phase. The exhaled flows are measured through the exhalation (distal and, as an option, proximal) pneumotacographs. The equipment has a system of valves that allows for a communication route between the pressure transducers and the ambient pressure. This way, the transducers can be zeroed. Simultaneously, a flow of air is pushed through to purge the exhalation pneumotacograph lines and prevent water and moisture from settling on the measurement elements. 2.2.13 | Safety Mechanisms GraphNet neo has a full safety system that includes the operational system that controls the microprocessor and various components that act independently from them. • WATCHDOG: This is a system that monitors the operation of the electronic circuit and exercises control independently from its integrity. When it detects an anomaly in the operation of the respirator, it allows it to discontinue and activates an emergency ventilation mode, the Emergency Ventilation. The Watchdog can activate the Emergency Ventilation in two different situations: - After 30 s have elapsed since the respirator has been turned on, without selecting a patient category, on the first initial calibration screen. - When the microprocessor loses control of the program sequence regulating ventilation. Technical specifications | GraphNet advance neo ts 2. 23 • EMERGENCY VENTILATION: the Emergency Ventilation is a safety mechanism that is activated in extreme conditions to provide the patient with temporary ventilation until measures can be taken to replace the respirator with an alternative ventilation mechanism. It is not a valid operational mode. The Emergency Ventilation allows delivery of respirations with characteristics that are similar to controlled pressure (PCV). During this event, only the peak pressure and the respiratory frequency are monitored. The predetermined values of the ventilation parameters are indicated in Table 2.2-15. The alarm limits are not enabled for modification. The active alarms are Maximum and minimum pressure, and maximum respiratory frequency, whose limits appear on screen. The only enabled complementary function is Manual Insp. Table 2.2-15 Ventilation parameters in Emergency Ventilation Parameter Initial value Range Observations Controlled pressure (PCV) 10 cmH2O 2 – 30 cmH2O The pressure is limited by maximum alarm pressure at 30 cmH2O. This limit cannot be changed. Ti (inhalation time) 0.70 s 0.10 – 3.00 s The inhalation time can be limited by the frequency value. Resp. frequency 20 rpm 1 – 100 rpm The frequency can be limited by the inhalation time. Inh. Sensitivity -2 cmH2O -0.5 – 20 cmH2O O2 Concentration 50 - Same value as in PCV mode Same range as in PCV mode Upload time Flow sensitivity not enabled. This parameter cannot be modified. WARNING • If the Emergency Ventilation is activated, provide the patient with an alternative ventilation mechanism and find out the cause of this event. If it has been activated because of a delay in the acceptance of the first initial calibration screen, restart the equipment to ventilate the patient. • SAFETY VALVE: it is located immediately before the patient output. It opens when the pressure in the patient circuit reaches a value of 120 ± 5 cmH2O. The mixture of gases goes to an internal collector and is expelled. • INHALATION RELEASE VALVE (ANTI-ASPHYXIATION): this valve makes it possible to bring ambient air to the patient when the equipment is off or when the respirator is not in operation. • OPERATIONAL GAS RELEASE: the gases that can seep into the equipment are recovered in a common collector and expelled. • LACK OF COMPRESSED AIR PRESSURE: compressed air is used as a pneumatic circuit command gas. When it is missing, it can be replaced with oxygen. In addition, when the equipment detects a lack of air, it automatically switches to a 100% O2 concentration. 2. 24 Technical specifications | GraphNet advance neo ts • LACK OF OXYGEN PRESSURE: in this case, air replaces oxygen and the respirations are delivered with a 21% O2 concentration. • AUTOMATIC ZERO: every 10 minutes or when the operator activates it (by pressing [Ctrl] + [Ctrl]) all pressure sensors are zeroed. This restarts the readings, preventing possible offset errors in the measured pressures. During the first few minutes of ventilation, the respirator can zero faster than indicated. For each zeroing, a message appears on the Icon and message bar indicating that this process is in progress. • CIRCUIT PURGE: to prevent obstructions and moisture from moving into the pressure sensors, air is injected through the patient circuit while the pressure sensors are being zeroed. • ALARM SYSTEM: GraphNet-neo has an alarm system to warn of situations that involve some degree of risk to the patient or to the equipment itself. Some make it possible to keep the condition from which it originated from continuing, others simply trigger signals to report its presence. For further information about how the alarm system works, see the Alarms chapter. • PARAMETER ADJUSTMENT: to avoid unnoticed parameter changes, it is necessary to execute sequences established on the respirator controls. This way, pressing a single key or the dial does not result in changes being entered. For this reason, the operator is always aware of the actions performed on the equipment. 2.2.14 | Pneumatic Circuit Respirator Fig. 2.2-1 Simplified pneumatic circuit respirator diagram.

The intensity of the fields generated by fixed transmitters, determined by local electromagnetic tests(3) must be lower than the level of compliance for each frequency range(4). There may be interference near the equipment marked with the following symbol: NOTE 1 For 80 MHz and 800 MHz, the greater frequency range applies. NOTE 2 This guide may not apply in all situations. The electromagnetic propagation is affected by absorption and reflexion from structures, objects and individuals. (1) ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40.66 MHz to 40.70 MHz. (2) The levels of compliance in ISM frequency bands between 150 kHz and 80 MHz and in the 80 MHz and 2.5 GHz frequency range have been established to reduce the possibility that a portable/mobile communications device may cause interference if inadvertently introduced into the patient’s area. For this reason, an additional factor of 10/3 has been included in the formula used to calculate the recommended separation distance for transmitters in those frequency ranges. (3) The field intensities of fixed transmitters, such as radio telephone (portable or wireless) base stations and land mobile radios, HAM radios, AM and FM and TV broadcasts cannot be precisely predicted theoretically. To find the value of the electromagnetic environment generated by fixed RF transmitters, an onsite test must be conducted. If the measurement of the field intensity in the location where GraphNet-ts is being used exceeds the above applicable RF compliance limits, GraphNet-ts must be evaluated to make sure that it can operate normally. If abnormal performance is observed, it may be necessary to take additional measures, such as reorienting or relocating the equipment. (4) In the 150 kHz and 80 MHz frequency range, the field intensity should be less than 10 V/m. 2. 34 Technical specifications | GraphNet advance neo ts 2.3.11.4 | Manufacturer’s statement: Separation distances Table 2.3-14 Recommended separation distances between the respirator and mobile/portable communication equipment GraphNet ts is intended to be used in an electromagnetic environment where radiated RF perturbances are controlled.

NOTE 1 For 80 MHz and 800 MHz, apply the separation distance for the larger frequency range. NOTE 2 ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40.66 MHz to 40.70 MHz. NOTE 3 An additional 10/3 factor has been included in the formula used to calculate the separation distance for transmitters that operate in the ISM frequency band between 150 kHz and 80 MHz and in the frequency range of 80 MHz to 2.5 GHz to reduce the likelihood that mobile and/or portable communication equipment can cause interference if they are inadvertently introduced in patient areas. NOTE 4 These guides may not apply in all situations. The electromagnetic propagation is affected by absorption and reflexion from structures, objects and individuals. 2.3.12 | Basic Respirator Operation GraphNet ts has a microprocessed control system that coordinates the tasks that arise from programming the equipment. All the actions performed by the respirator are commanded by this system. The flow of gas received by the patient is administered by two proportional valves, one for air, the other for oxygen. The valves operate simultaneously, providing the appropriate oxygen concentration and the necessary flow wave characteristics. The exhalation valve is controlled by two attached valves. One of them, with ON/ OFF features, tells it to open or close, which determines the end and the beginning of the inhalation phase, respectively. The other valve is proportional, and is in charge of regulating the PEEP level when it is configured. The microprocessor is re-fed with signals that come from the sensor system in the respirator. This makes it possible to control and adjust the configured ventilatory program. Airway pressure is measured with a transducer related to a sensor on the end of the patient circuit (exhalation set). The signal that comes from this transducer is also used to trigger inhalations when the pressure sensitivity, respiration cycling, alarm levels and others, are enabled. The proximal pressure is measured Technical specifications | GraphNet advance neo ts 2. 35 with a transducer next to the patient output. The most relevant task of this item is pressure control in pressure controlled or support pressure mode respirations. Flow information is obtained through two differential pressure transducers related to the internal output pneumotacograph and to the exhalation pneumotacograph. The internal pneumotacograph (Silverman mesh type) makes it possible to control the flows and volumes driven by the respirator in the inhalation phase. The exhaled flows are measured through the exhalation pneumotacograph. The equipment has a system of valves that allows for a communication route between the pressure transducers and the ambient pressure. This way, the transducers can be zeroed. Simultaneously, a flow of air is pushed through to purge the exhalation pneumotacograph lines and prevent water and moisture from settling on the measurement elements. 2.3.13 | Safety Mechanisms GraphNet ts has a full safety system that includes the operational system that controls the microprocessor and various components that act independently from them. • WATCHDOG: This is a system that monitors the operation of the electronic circuit and exercises control independently from its integrity. When it detects an anomaly in the operation of the respirator, it allows it to discontinue and activates an emergency ventilation mode, the Emergency Ventilation. The Watchdog can activate the Emergency Ventilation in two different situations: - After 30 s have elapsed since the respirator has been turned on, without selecting a patient category, on the first initial calibration screen. - When the microprocessor loses control of the program sequence regulating ventilation. • EMERGENCY VENTILATION: the Emergency Ventilation is a safety mechanism that is activated in extreme conditions to provide the patient with temporary ventilation until measures can be taken to replace the respirator with an alternative ventilation mechanism. It is not a valid operational mode. The Emergency Ventilation allows delivery of respirations with characteristics that are similar to controlled pressure (PCV). During this event, only the peak pressure and the respiratory frequency are monitored. The predetermined values of the ventilation parameters are indicated in Table 2.3-15. The alarm limits are not enabled for modification. The active alarms are Maximum and minimum pressure, and maximum respiratory frequency, whose limits appear on screen. The only enabled complementary function is Manual Insp. 2. 36 Technical specifications | GraphNet advance neo ts Table 2.3-15 Ventilation parameters in Emergency Ventilation Parameter Initial value Range Observations Controlled pressure (PCV) 10 cmH2O 2 – 30 cmH2O The pressure is limited by maximum alarm pressure at 30 cmH2O. This limit cannot be changed. Ti (inhalation time) 0.70 s 0.10 – 3.00 s The inhalation time can be limited by the frequency value. Resp. frequency 20 rpm 1 – 100 rpm The frequency can be limited by the inhalation time. Inh. Sensitivity -2 cmH2O -0.5 – 20 cmH2O O2 Concentration 50 - Same value as in PCV mode Same range as in PCV mode Upload time Flow sensitivity not enabled. This parameter cannot be modified. WARNING • If the Emergency Ventilation is activated, provide the patient with an alternative ventilation mechanism and find out the cause of this event. If it has been activated because of a delay in the acceptance of the first initial calibration screen, restart the equipment to ventilate the patient. • SAFETY VALVE: it is located immediately before the patient output. It opens when the pressure in the patient circuit reaches a value of 120 ± 5 cmH2O. The mixture of gases goes to an internal collector and is expelled. • INHALATION RELEASE VALVE (ANTI-ASPHYXIATION): this valve makes it possible to bring ambient air to the patient when the equipment is off or when the respirator is not in operation. • OPERATIONAL GAS RELEASE: the gases that can seep into the equipment are recovered in a common collector and expelled. • LACK OF COMPRESSED AIR PRESSURE: compressed air is used as a pneumatic circuit command gas. When it is missing, it can be replaced with oxygen. In addition, when the equipment detects a lack of air, it automatically switches to a 100% O2 concentration. • LACK OF OXYGEN PRESSURE: in this case, air replaces oxygen and the respirations are delivered with a 21% O2 concentration. • AUTOMATIC ZERO: every 10 minutes or when the operator activates it (by pressing [Ctrl] + [Ctrl]) all pressure sensors are zeroed. This restarts the readings, preventing possible offset errors in the measured pressures. During the first few minutes of ventilation, the respirator can zero faster than indicated. For each zeroing, a message appears on the Icon and message bar indicating that this process is in progress. •CIRCUIT PURGE: to prevent obstructions and moisture from moving into the pressure sensors, air is injected through the patient circuit while the pressure sensors are being zeroed. Technical specifications | GraphNet advance neo ts 2. 37 • ALARM SYSTEM: GraphNet-ts has an alarm system to warn of situations that involve some degree of risk to the patient or to the equipment itself. Some make it possible to keep the condition from which it originated from continuing, others simply trigger signals to report its presence. For further information about how the alarm system works, see the Alarms chapter. • PARAMETER ADJUSTMENT: to avoid unnoticed parameter changes, it is necessary to execute sequences established on the respirator controls. This way, pressing a single key or the dial does not result in changes being entered. For this reason, the operator is always aware of the actions performed on the equipment. 2.3.14 | Pneumatic Circuit Respirator Fig. 2.3-1 Simplified pneumatic circuit respirator diagram.
