SYSTEMS AND METHODS FOR IDENTIFYING VENTILATED BREATHING

摘要

Provided are systems and methods for processing a physiological signal in order to detect whether a patient's breathing is being controlled by a ventilator. A signal, such as a photoplethysmograph (PPG) may be processed to determine one or more various metrics indicative of the consistency of the patient's respiration.

主权项

1. A computer-implemented method comprising:
receiving a photoplethysmograph (PPG) signal; generating, using processing circuitry, at least one signal indicative of respiration consistency based on the PPG signal; identifying, using the processing circuitry, a presence of ventilated breathing based on the at least one signal indicative of respiration consistency; and providing, using the processing circuitry, an indicator of ventilated breathing based on the identifying of the presence of ventilated breathing.
