Systems and methods for generating an artificial photoplethysmograph signal

摘要

A test unit may generate a pulse signal based on a pulsatile profile and a frequency modulation component of a respiratory profile. A respiration modulated signal may be generated from the pulse signal, an amplitude modulation component, and a baseline modulation component. A patient modulated signal may be generated based on the respiration modulated signal and a patient profile. The artificial PPG signal may be generated based on the patient modulated signal and an artifact profile. The artificial PPG signal may be output to an electronic device.

1. A method for generating an artificial photoplethysmograph (PPG) signal using a test unit, the method comprising:
generating, using the test unit, a frequency modulation component, an amplitude modulation component, and a baseline modulation component based at least in part on a respiratory profile; generating, using the test unit, a pulse signal based at least in part on a pulsatile profile and the frequency modulation component; modifying, using the test unit, the pulse signal based at least in part on the amplitude modulation component and the baseline modulation component to generate a respiration modulated signal; generating, using the test unit, the artificial PPG signal based at least in part on the respiration modulated signal; and outputting, using the test unit, the artificial PPG signal to a physiological monitor.
