1. A neonatal cerebral oxygenation monitoring apparatus comprising:

  • a wearable support sized and configured to cover at least a portion of a head of an infant to be secured thereto, the wearable support comprising a posterior portion configured to be placed over a posterior portion of the infant'"'"'s head when the wearable support is secured to the head of the infant;

    a light emitter positioned on the posterior portion of the wearable support so that the light emitter faces and emits toward a superior sagittal sinus of the infant'"'"'s head when the wearable support is secured onto the infant'"'"'s head; and

    an acoustic sensor positioned on the posterior portion of the wearable support so that the acoustic sensor faces the posterior portion of the head of the infant to detect acoustic pressure generated by blood in the superior sagittal sinus when the superior sagittal sinus blood absorbs the light,wherein cerebral blood oxygenation is determined in response to the acoustic pressure detected by the acoustic sensor, and wherein the light emitter is configured to emit the light through a posterior fontanelle of the infant'"'"'s head, and wherein the acoustic sensor is configured to detect the acoustic pressure through the posterior fontanelle.
