Pulse oximeter with an accelerometer
First Claim
Patent Images
1. A method for controlling a pulse oximeter, comprising:
- receiving accelerometer data from an accelerometer coupled to the pulse oximeter;
determining a patient activity state based at least in part on the received accelerometer data;
determining whether the patient activity state is not a rest state;
setting a sampling rate of the pulse oximeter to a first level based on whether the patient activity state is not a rest state,determining whether the patient activity state is a rest state;
setting the sampling rate of the pulse oximeter to a second level based on whether the patient activity state is a rest state, wherein the second level is a lower sampling rate than the first level; and
controlling the pulse oximeter to take measurements in response to the determined patient activity state.

Abstract
Systems, methods, and devices of the various embodiments provide a pulse oximeter capable of taking blood oxygen readings based on readings from an accelerometer. The various embodiments may provide an electronic patch including a pulse oximeter and accelerometer connected to a processor, wherein the processor is configured with processor executable instructions to control the operation of the pulse oximeter based at least in part on data received from the accelerometer. In various embodiments the electronic patch may further include a coin cell battery, or other low power source, that may power the pulse oximeter.
