The wireless NIRS sensor will be placed on the participant's forehead, directly underneath the INVOS wired sensor. The wireless NIRS sensor will remain in place for 4 consecutive hours, over 2 consecutive days. As standard-of-care, nursing personnel removes all sensors at every care to evaluate skin and reduce the risk of pressure sores. The wireless NIRS device will be removed and reapplied at the same time, by the research team who will annotate what time the sensor was removed, replaced, and the condition of the skin. This will be used to correlate signal disconnection with sensor care (i.e., skin checks, sensor removal, etc.).
Infants admitted to the NICU with a gestational age of ≥ 32 weeks at the time of the monitoring
undergoing monitoring with the INVOS wired NIRS system.
Infants with a skin abnormality that would potentially increase the risk of injury,
Patient too unstable or family experiencing too much stress as determined by an attending physician or bedside care team to not be approached for recruitment.

Provide a questionnaire to capture the perspectives of clinicians and patients' parents/guardians regarding use of the wireless NIRS compared to wired NIRS device.
Provide a a custom study questionnaire to capture the perspectives of clinicians and patients' parents/guardians regarding use of the wireless NIRS compared to wired NIRS device. The questionnaire includes Likert-scale items, multiple-choice questions, and open-ended responses evaluating usability, perceived safety, accuracy, comfort, and acceptability. Responses will be summarized descriptively by questionnaire item.
