1. A process for controlling a respirator, the process comprising the steps of:
- providing a first oxygen saturation monitor;
providing a second oxygen saturation monitor;
detecting a first measurement signal with said first oxygen saturation monitor, said first measurement signal comprising a first patient blood oxygen saturation measurement;
detecting a second measurement signal with said second oxygen saturation monitor, said second measurement signal comprising a second patient blood oxygen saturation measurement;
determining a measuring reliability rating for each of said first measurement signal and said second measurement signal when said first patient blood oxygen saturation measurement and said second patient blood oxygen saturation measurement are greater than or equal to a predetermined oxygen saturation threshold;
selecting at least one of said first measurement signal associated with said first oxygen saturation monitor and said second measurement signal associated with said second oxygen saturation monitor based on said measuring reliability rating to define at least one selected measurement signal;
controlling an oxygen concentration delivered to the patient based on said at least one selected oxygen saturation measurement.

Abstract
A process and a device for oxygen regulation of a patient having at least two SPO2 monitors and a control for automatic recognition of which measurements are more reliable. The measurement from one or more of the two SPO2 is used to control the oxygen concentration delivered to a patient based on a comparison of the measurements from the at least two SPO2 monitors.
