CPAP/BiPAP Study: 1. Patient Evaluation: Before the study, the sleep specialist evaluates the patient's medical history, medications, and physical examination to determine the need for a CPAP/BiPAP study. 2. Setup: The patient is brought to the sleep center and prepared for the study. The patient is attached to a polysomnogram, which records brain waves, muscle activity, eye movements, heart rate, and breathing patterns. 3. Baseline Data Collection: The technician records baseline data, including the patient's oxygen saturation, heart rate, and breathing patterns during sleep without the use of CPAP/BiPAP. 4. CPAP/BiPAP Titration: Once baseline data is collected, the technician initiates CPAP/BiPAP therapy and increases the pressure to determine the optimal pressure to prevent sleep apnea events. This process involves gradual pressure increments until the optimal pressure is determined, and the patient's breathing patterns are stable. 5. Monitoring: During the study, the technician monitors the patient's breathing patterns, oxygen saturation, heart rate, and sleep stages. 6. Adjustments: If necessary, the technician adjusts the CPAP/BiPAP pressure to ensure optimal treatment. 7. Data Analysis: After the study, a sleep specialist reviews the data to determine the effectiveness of CPAP/BiPAP therapy. Split Night Titration Study: 8. Diagnostic Portion: The patient undergoes a standard sleep study (polysomnography) to diagnose sleep apnea and determine the severity of the condition. 9. Baseline Data Collection: Before initiating CPAP/BiPAP therapy, the technician records baseline data, including the patient's oxygen saturation, heart rate, and breathing patterns during sleep. 10. CPAP/BiPAP Initiation: If sleep apnea is diagnosed during the diagnostic portion, the technician initiates CPAP/BiPAP therapy and gradually increases the pressure to determine the optimal pressure to prevent sleep apnea events. 11. Monitoring: During the study, the technician monitors the patient's breathing patterns, oxygen saturation, heart rate, and sleep stages. 12. Adjustments: If necessary, the technician adjusts the CPAP/BiPAP pressure to ensure optimal treatment. 13. Split Night Criteria: The patient must meet specific criteria to qualify for a split night study. The criteria include the number of sleep apnea events during the diagnostic portion, the severity of the condition, and the ability to tolerate CPAP/BiPAP therapy. 14. Data Analysis: After the study, a sleep specialist reviews the data to determine the effectiveness of CPAP/BiPAP therapy and diagnose sleep apnea. Sources: • • American Academy of Sleep Medicine.
