  • Publication number: 20210219882
    Abstract: Methods and systems are provided for a pulse oximetry probe configured to measure blood originating from the internal carotid artery. One example system includes a light emitter and a light detector coupled to a substrate and an attachment mechanism configured to couple the nasal pulse oximetry probe to a nose of a patient, the light emitter and light detector positioned on opposite sides of the nose at the root of the nasal bridge. One example method determines peripheral arterial oxygen saturation (SpO2) respiratory variability as well as other physiological parameters from measurements taken from the internal carotid artery.

  • Publication number: 20210121109
    Abstract: Methods and systems are provided for a light-emitting diode (LED) drive circuit of an optical probe. As an example, a method for an optical probe including an LED in an LED drive circuit comprises reducing power consumption of the LED drive circuit by adjusting a drive voltage of the LED drive circuit based on one or more LED drive circuit characteristics and one or more LED drive circuit operating parameters. In this way, the LED drive circuit may be efficiently operated.

  • Publication number: 20210068761
    Abstract: Methods and systems are provided for lowering power consumption in an optical sensor, such as a pulse oximeter. In one example, a method for an optical sensor includes illuminating a light emitter of the optical sensor according to set sensor parameters, the sensor parameters set based on hardware noise or external interference characterization and light transmission or reflection of a tissue contributing to a signal output by the optical sensor, the sensor parameters including current drive parameters of the light emitter, and adjusting the current drive parameters of the light emitter to maintain a target signal to noise ratio of the signal output by the optical sensor.
