Low power and personal pulse oximetry systems
First Claim
Patent Images
1. A method of reducing power used in a pulse oximetry system, the method comprising the steps of:
- receiving intensity signals generated by the detection of light attenuated by a fleshy medium;
processing said intensity signals so as to provide a physiological measurement; and
disabling at least one of said intensity signals so as to reduce power consumption.

5. A low power pulse oximetry method comprising the steps of:
-
establishing a baseline measurement responsive to at least one of first and second intensity signals generated by the detection of light having at least first and second wavelengths after absorption by constituents of pulsatile blood flowing within a fleshy medium;
providing a subsequent measurement responsive to at least one of said intensity signals;
comparing said subsequent measurement to said baseline measurement; and
based on said comparing, foregoing a signal processing technique relating to at least one of said intensity signals so as to reduce power consumption. - View Dependent Claims (6, 7)

8. A monitoring system comprising:
-
a personal pulse oximeter configured to process one or more intensity signals indicative of one or more physiological parameters of a monitored patient;
a sensor configured to output the one or more intensity signals;
a wireless adapter configured to control communication between the personal pulse oximeter and the sensor; and
an external patient monitoring system capable of communicating with the personal pulse oximeter. - View Dependent Claims (9, 10, 11)
