1. A computer-implemented method comprising:
- receiving a photoplethysmograph (PPG) signal;
generating, using processing circuitry, one or more respiration morphology signals based on the PPG signal;
calculating, using the processing circuitry, a threshold value for each of the one or more respiration morphology signals;
comparing, using the processing circuitry, data indicative of each morphology signal to a respective one of the threshold values; and
identifying, using the processing circuitry, a held breath event based at least on the comparing.

Abstract
Systems and methods are provided for detecting held breath events. A physiological signal, such as a photoplethysmograph (PPG) signal, is processed to extract respiration-related morphology metric signals. The morphology signals are analyzed to determine when a patient'"'"'s breath is being held.
