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.

Abstract
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.
