Claim:
1. A method for measuring oxygen saturation of a patient's blood comprising: operating a pulse oximeter in a high power mode, the pulse oximeter utilizing a sensor configured to generate data indicative of the oxygen saturation of the patient's blood; comparing, via a processor of the pulse oximeter, the data generated by the pulse oximeter to a plurality of predefined data profiles that includes a first data profile associated with a moving patient and a second data profile associated with an improperly positioned pulse oximeter on the patient; detecting, via the processor, that the data matches the first data profile or the second data profile; selecting, via the processor, a low power mode from a plurality of different low power modes that consume comparatively less power than the high power mode, wherein a first low power mode of the plurality of different low power modes is selected when the data matches the first data profile and a second low power mode of the plurality of different low power modes that is different from the first low power mode is selected when the data matches the second data profile; switching, via the processor, the pulse oximeter from the high power mode to the selected first low power mode or second low power mode for a first time interval; monitoring, via the processor, the oxygen saturation of the patient's blood while the pulse oximeter is in the selected first low power mode or second low power mode; and after the first time interval, returning, via the processor, the pulse oximeter to the high power mode.
