Patent ID: 8485981

Claim:
A method for synchronizing operation between a patient monitoring device and a ventilator, comprising: detecting an initial status of the ventilator, the initial status indicating completion of at least one of an inspiration stroke and an expiration stroke; starting a procedure performed by the patient monitoring device in response to the initial status of the ventilator; monitoring an operating status of at least the patient monitoring device while the procedure is performed; while monitoring the operating status of at least the patient monitoring device, detecting an impending event of the ventilator, the impending event to be detected is expiration when the initial status indicates completion of the inspiration stroke, and inspiration when the initial status indicates completion of the expiration stroke; while the procedure is performed, delaying at least one of a next inspiration stroke when inspiration is detected to be imminent and a next expiration stroke when expiration is detected to be imminent, wherein the delaying does not exceed a predetermined time; and automatically aborting the procedure prior to completion of the procedure and prior to elapsing of the predetermined time when the operating status of at least the patient monitoring device indicates an abort condition, the abort condition being determined in response to a measured patient physiological parameter exceeding a threshold.
