Abstract: A peripheral oxygen saturation (SpO2) response time (also referred to as a patient response time) may be determined automatically by a ventilator and used as part of a process for controlling the inspired oxygen fraction (FIO2) level delivered to the patient. Accordingly, the SpO2 response time for a given patient can be determined and used to adjust how quickly the FIO2 level is changed (e.g., more quickly for a patient having a shorter response time and more slowly for a patient having a longer response time). The ventilator may enter a particular operation mode (e.g., a response time procedure) to determine the patient response time. The ventilator may be designed to pause closed loop control of the FIO2 level and execute the response time procedure to determine the patient response time. The ventilator may return to FIO2 closed loop control at the conclusion of the response time procedure.

Abstract: The present invention relates to systems and methods for multi-frequency oscillatory ventilation (MFOV). The system uses a broadband flow waveform more suitable for the heterogeneous mechanics of the lung. The system provides more efficient gas exchange and enhanced lung recruitment at lower airway pressures.
