Abstract
A method of approximating a position of an oxygen mask during a procedure includes detecting a presence of the oxygen mask based on a signal from a sensor or through an observation through an optical imaging device; determining whether the oxygen mask is close to or on a patient for supplying oxygen to the patient; detecting a removal of the oxygen mask from the patient to stop supplying oxygen to the patient; initiating a desaturation timer in response to the sensor or the optical imaging device detecting the removal of the oxygen mask from the patient; and operating an image display device to display a parameter for the oxygen desaturation timer.
