Conducting Polysomnography (PSG): The respiratory physiologist assists with the setup and monitoring of sleep studies, ensuring accurate measurement of respiratory parameters such as airflow, oxygen levels, and respiratory effort throughout the night. Monitoring and Interpreting Respiratory Data: During the study, they track and interpret key data like apnea-hypopnea index (AHI), oxygen desaturation, and respiratory patterns to assess the severity of sleep-disordered breathing. Equipment Setup and Calibration: They are responsible for properly setting up and calibrating the equipment used in sleep studies, ensuring all respiratory sensors are correctly placed and functioning. Patient Care and Comfort: Ensuring that patients are comfortable during the study, explaining procedures, and addressing any concerns, as well as providing ongoing support throughout the night. Collaboration with Sleep Specialists: The respiratory physiologist works closely with sleep physicians and other healthcare providers to help interpret the data, contributing to a comprehensive diagnosis and treatment plan for conditions such as obstructive sleep apnea or central sleep apnea. Data Review and Reporting: After the study, the respiratory physiologist reviews the collected data, identifies key findings, and prepares detailed reports for the sleep specialist to aid in diagnosis.
