Claim:
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.
