MONITORING SYSTEM INCLUDING MASK REMOVAL AND OXYGEN

摘要

A method of indicating an oxygen desaturation period has been initiated includes detecting an oxygen mask configured to supply oxygen to a patient to saturate the patient, detecting a removal of the oxygen mask from the patient to stop saturation of the patient, initiating a desaturation timer in response the removal of the oxygen mask from the patient, and operating an image display device to display a first running time on a screen of the image display device indicating a desaturation time elapsed from a time of the removal of the mask.
