System for generating noninvasive respiratory monitor signals

摘要

A system for simulating various clinical conditions which are detectable by a noninvasive respiratory monitor is provided. The simulated clinical conditions may be displayed on a noninvasive respiratory monitor to replicate a variety of disease states to provide training for a clinician. The system may include a pulse oximetry simulation device and/or a CO2 delivery system.

主权项

1. A system for generating simulated noninvasive respiratory monitor signals comprising:
a pulse oximetry simulation device configured to generate a first signal that is detectable by a noninvasive respiratory monitor; a CO2 delivery system configured to generate a second signal that is detectable by a noninvasive respiratory monitor, wherein the second signal that is detectable by a noninvasive respiratory monitor is a flow of air having a concentration of CO2; a control valve configured to deliver the concentration of CO2 in the flow of air and wherein the control valve is configured to deliver a variable flow of CO2; a computer system disposed in communication with the pulse oximetry simulation device and the CO2 delivery system, wherein the computer system is configured to digitally control the potentiometer to thereby modulate the first signal and the second signal; wherein the pulse oximetry simulation device further comprises one or more photodetectors and a LED, and wherein the first signal that is detectable by the noninvasive respiratory monitor is light emitted from the LED; and wherein the digitally controlled potentiometer is in electrical communication with the LED, and wherein the digitally controlled potentiometer is configured to modulate the intensity of the light emitted by the LED.
