Abstract
A method includes increasing or decreasing a temperature of an oximeter device by cycling oximetry measurements and temperature adjustment at a predetermined frequency. During temperature adjustment, power supplied to LEDs of the oximeter device may be modulated to heat or cool the oximeter device if the oximetry device is above a temperature setpoint or below the temperature setpoint. After the device is heated to the temperature setpoint an oximetry measurement is made using the LED to illuminate patient tissue, detected the light from the tissue after illumination, and determining oximetry information for the tissue. Using the LED for heating and oximetry measurements reduces electronic components of the device improves reliability from the reduction of electronic components. The device can also not power the LEDs to allow the device to cool if the temperature is above the temperature setpoint.
