Abstract: An oximetry sensor includes a light source configured to emit first light into a tissue of a patient, the first light comprising a first light wavelength greater than a threshold wavelength and a light filter. The light filter is configured to receive the first light from the tissue of the patient, filter a second light wavelength from at least one of the received first light or ambient light. The second light wavelength is less than or equal to the threshold wavelength. The light filter is also configured to output a filtered light that includes the received first light from the tissue. The oximetry sensor also includes a detector configured to detect the filtered light, the filtered light being indicative of an oxygen saturation level of the patient.

Abstract: In some examples, a kit includes a pulse oximetry sensor patch and a stretchable pressure backing configured to be applied to a region of a patient's skin. An assembly may include the stretchable pressure backing securing the pulse oximetry sensor patch against the patient's skin. The stretchable pressure backing is configured to stretch across the pulse oximetry sensor patch from an unstretched length to a stretched length. When in its stretched length, the stretchable pressure backing is configured to press the pulse oximetry sensor patch against the patient's skin to apply pressure to reduce venous pulsations in the region of the patient's skin. An example technique includes applying the pulse oximetry sensor patch to the patient's skin and stretching the stretchable pressure backing across the pulse oximetry sensor patch to its stretched length to apply pressure to the pulse oximetry sensor patch to reduce venous pulsations.

Abstract: The present disclosure provides systems and methods for improving signal-to-noise ratio (SNR) for a medical device sensor operating in reflective mode such that light from an emitter travels through tissue via reflection to a first detector at a first depth to provide a first detected signal over time and such that light from the emitter travels through tissue via reflection to a second detector at a second, greater depth to provide a second detected signal over time, with subtracting out the signal from superficial tissue that is common to the first and the second detected signals to provide an improved signal-to-noise ratio for the medical device sensor.
