| 摘要 |
The present disclosure pertains to an exhalation valve system (10) configured to control gas flow during exhalation of a subject (12). In some embodiments, the system comprises one or more of a pressure generator (14), a subject interface (16), one or more sensors (18), one or more processors (20), electronic storage (22), user interface (23), and/or other components. The system is configured to adjust a rebreathing level of the subject based on detected occurrences of disordered breathing events. By rebreathing exhaled air (and/or other breathable gas) a subject may minimize and/or prevent central sleep apneas. The system monitors the breathing of the subject to detect occurrences of respiratory events related to central sleep apnea. The system monitors accumulated retrograde breathing and adjusts the volume of exhaled rebreathing and/or other system settings affecting the subject's breathing. Through these adjustments, the system may prevent and/or reduce respiratory events related to central sleep apnea. |
