Patent ID: 8640700

Claim:
A method for controlling the delivery of a breathing gas to a patient using a ventilator, the method including: regulating the delivery of the breathing gas delivered to the patient; determining a value of a first physiologic parameter of the patient, wherein the first physiologic parameter is a saturation of peripheral oxygen (SpO 2 ) of the patient; comparing the determined value of the first physiologic parameter of the patient to a clinician-selected target physiologic value, which is a target of SpO 2 for the first physiologic parameter of the patient; automatically adjusting the breathing gas delivered to the patient in response to the comparison between the determined value of the first physiologic parameter of the patient and the clinician-selected target physiologic value for the first physiologic parameter; and automatically determining a new target physiologic value, which is a new target of SpO 2 for the first physiologic parameter, based at least in part on the determined value of the first physiologic parameter of the patient.
