1. A method for controlling a ventilator in communication with a patient, the method comprising:
- calculating a first oxygen saturation value based at least in part on a first signal generated by a first sensor attached to the patient;
calculating a second oxygen saturation value based at least in part on a second signal generated by a second sensor attached to the patient;
determining with processing equipment at least one setting for the ventilator based at least in part on the first oxygen saturation value and the second oxygen saturation value, wherein the determined at least one setting comprises a fractional inspired oxygen setting of the ventilator; and
applying the at least one setting.

Abstract
A method and system for controlling a ventilator is disclosed. Oxygen saturation values from pulse oximeters may be used to adjust the settings of a ventilator. Multiple sensors and multiple oxygen saturation values in a fault tolerant pulse oximeter configuration may be used to provide a backup value or confidence measure, thereby increasing reliability and patient safety.
