Method and system for determining when to reposition a physiological sensor
First Claim
Patent Images
1. A method for notifying an operator to reposition a sensor, comprising the acts of:
- starting a timer upon application of a sensor to a patient, wherein the timer is set to run for a time interval;
resetting the timer if the sensor is repositioned prior to the expiration of the time interval; and
prompting a caregiver to reposition the sensor at the expiration of the time interval.

Abstract
A sensor may be placed on a patient to obtain physiological measurements. The application of the sensor on the patient may start a timer set to run for a given time interval. If the sensor is repositioned before the interval is expired, the timer is reset. If the time expires without the sensor being repositioned, a caregiver is prompted to reposition the sensor.

29. A physiological monitoring system, comprising:
-
a sensor comprising at least one emitter and at least one detector; and
a monitor comprising a timer set to run for a time interval and at least one of a display or speaker, wherein the timer is configured to start when the sensor is applied to a patient and to reset if the sensor is repositioned prior to the expiration of the time interval and wherein the at least one of a display or a speaker is configured to provide a prompt if the sensor is not repositioned during the time interval. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)
