Claim of US Patent No. 11,109,782


1. A method for monitoring one or more of cerebral oxygenation or total hemoglobin concentration of an infant, the method comprising:emitting light from a light emitter secured to a head of the infant with a wearable support secured onto the infant's head, wherein the wearable support is sized and configured to cover at least a portion of the infant's head to be secured thereto, and wherein the light emitter is positioned on the wearable support so the light emitter faces and emits light toward a superior sagittal sinus of the infant's head through a fontanelle;
detecting, with an acoustic sensor secured to the infant's head with the wearable support, acoustic pressure generated by blood in the superior sagittal sinus in response to the emitted light, wherein the acoustic sensor is positioned on the wearable support to one or more of an anterior portion or a posterior portion of the infant's head to detect the acoustic pressure generated by blood in the superior sagittal sinus through the fontanelle; and
determining, with a processor in communication with the light emitter and the acoustic sensor, the one or more of cerebral blood oxygenation or total hemoglobin concentration in response to the detected acoustic pressure.
