Methods and systems for determining a probe-off condition in a medical device

摘要

A physiological monitoring system may determine a probe-off condition. A physiological sensor may be used to emit one or more wavelengths of light. A received light signal may be processed to obtain a light signal corresponding to the emitted light and an ambient signal. The signals may be analyzed to identify similar behavior. The system may determine whether the physiological sensor is properly positioned based on the analysis.

主权项

1. A method for determining whether a physiological sensor is properly positioned on a subject, the method comprising:
receiving a light signal using the physiological sensor; processing, using processing equipment, the light signal to obtain a first signal corresponding to ambient light; processing, using the processing equipment, the light signal to obtain a second signal corresponding to an emitted photonic signal and ambient light; analyzing, using the processing equipment, the first signal and the second signal to identify similar signal amplitude behavior; and determining, using the processing equipment, that the physiological sensor is not properly positioned based on the analysis.
