The MLS340 Cardiac Output Module for Windows provides the user with an analysis tool to easily extract and calculate cardiac output from small animals, using the thermodilution technique and recorded in Chart. Depending on the injectate temperature, there may be some permanent cooling of the blood. As the cold/cooled fluid is recirculated the thermodilution curve does not return to its baseline value. The Tail fitting range allows the user to define a portion of the downslope of the recorded thermodilution curve from which an exponential curve is calculated and extrapolated to a baseline. The portion of the downslope used in this calculation is specified as a percentage of the curve full height. The Cardiac Output Module should be used with the latest version of Chart. Click here for the latest Chart Update for Windows. The module calculates: • cardiac output in mL/min • baseline temperature • area under the thermodilution curve • baseline slope correction The baseline temperature is important in calculating CO and is calculated for each thermodilution curve created and analyzed. The user in selecting the curve is also required to define a period of time prior to the thermodilution curve for the module to determine baseline temperature. Two parameters are required from the user: It also adds values to the Data Pad from which data can be exported to other applications. 1. The Onset time defines the period of time there is beginning to be a temperature change (the data in this period will not be used for the Contact baseline calculation). Us The module includes three main dialog windows: 1. Cardiac Output Window 2. Cardiac Output Settings 3. Set Baseline Correction 1. Cardiac Output Window 2. The user sets the time interval for baseline temperature determination in the Calculate baseline from text box. The module will calculate the baseline over this time interval, with the period selected ending at the start of the onset period (see Cardiac Output window above). 3. Set Baseline Correction Any baseline drift can also be corrected by selecting baseline data and choosing Set Baseline Correction from the Cardiac Output menu. Selecting OK will automatically insert the correction factor in the CO calculation, or it can be turned on or off in the Settings dialog box by checking or unchecking the Baseline slope correction text box. The capture option in the Setting dialog box allows the user to mark the selected thermodilution curve with the CO values as well as automatically adding the calculated values for each thermodilution curve to the Data Pad.

The DMT Normalization Module is for use with PowerLab, Chart and DMT Wire Myographs. The DMT Normalization Module should be used with the latest version of Chart. Click here for the latest Chart Update for Windows. The module: • Automatically calculates tissue length • Provides online and offline determination of effective pressure • Calculates the pre-tension (micrometer setting) for normalization A graph of internal circumference versus resting wall tension is created with each stepwise distension, with the module ending once the effective pressure exceeds 100 mmHg (13.3 kPa). An exponential curve is then fitted to the internal circumference pressure data and, using Laplace's equation, the point on the curve corresponding to 100 mmHg is determined and denoted IC100. From the IC100 a value IC1 is calculated (0.9 x IC100) which the module then uses to calculate the micrometer setting which sets the internal circumference to this pressure. The module has been set with a default of 0.9 (rat mesenteric vessels) this ratio (IC1/IC100) should be determined for different tissue types. The rationale and theory behind normalizing elastic tissues such as microvessels has been extensively investigated by Professor Michael DMT Normalization window with stepwise distension of the tissue using the micrometer and Mulvany (for details see Mulvany MJ, Halpern, W Circulation Research the developed force. The graph on the right is automatically generated from the calculated 1977, 41: 19-26). Mulvany determined that the optimal pre-tension internal circumference and resting wall tension by the module. conditions (ie internal circumference) for microvascular studies is best defined as the size when the vessel is fully relaxed and under a Contact Normalization Settings dialog transmural pressure of 100 mmHg. Therefore the aim of the normalizationUs procedure is to determine the internal circumference at which the vessel The DMT Normalization Module would be relaxed and under a transmural pressure of 100 mmHg. This provides a Normalization Settings index is denoted as IC100 and is calculated for each vessel mounted on dialog box in which microscope the wire myograph. eyepiece calibration, target pressure, IC1/IC100 ratio, online averaging and There are a number of factors which need to be considered when delay time can be entered which are conducting studies using elastic tissues, these include: used in the calculations which will be 1.

The module also useful to set vessels to an internal circumference which gives the provides the user with the micrometer setting for achieving the desired maximum response. pre-tension conditions for the tissue being studied. It is therefore important to define the experimental conditions prior to conducting investigations into the properties of elastic tissues. The normalization procedure is performed by distending the vessel stepwise and measuring sets of micrometer readings whilst recording the developed force using PowerLab and Chart. The DMT Normalization Module calculates the internal circumference from the measured distance between the wires, known diameter of the wire and length of tissue used. The length of the tissue is determined using a calibrated eyepiece and microscope. Wall tension is the measured force divided by the wall length from which effective pressure is calculated. Effective pressure is an estimate of the pressure which would be necessary to extend the vessel to the measured internal circumference.

Physical Configuration: Dimensions (h x w x d) 50 x 76 x 260 mm (1.96 x 3.0 x 10.2 in) Compatibility Weight 750 g (1 lb 10.5 oz) The GSR Amp is compatible with all PowerLab and MacLab models and requires Chart v4 or later or Scope v3.5 or later. Power Requirements 2.5 W maximum Operating Temperature Range 0 to 35 °C, 0 to 90% humidity (noncondensing) Operation The 75 Hz oscillator supplies a near square wave, low-impedance, lowvoltage (22 mVrms) signal to an electrode on one finger of the subject. If the skin has a measurable conductance, current flows from the electrode on the other finger back into the very low impedance input of the transimpedance amplifier. The current is then converted to a voltage signal. The current will change as the autonomic reflexes change the skin’s conductivity. • Do not use recording gel with the electrodes. This will tend to give higher basal readings as skin resistance is lowered by gel. • Avoid measuring skin conductance if the subject is perspiring excessively at rest.

Ice Point Reference compensation is provided by the direct measurement of the input connector temperature. The equivalent voltage is subtracted from the thermocouple voltage to compensate for the changes in the ambient temperature. Temperature changes are typically slow and filtering is provided by a 2 pole 10 Hz Butterworth filter. This will provide adequate filtering from mains power supply and allow fast temperature transients to be monitored. Note: The output of the Pod is not linearized.
