The study will evaluate the feasibility of Nonin SenSmart H500 device to measuring brain oxygenation during prehospital anesthesia of adult patient. The study also estimates the incidence of cerebral hypoxic events of anesthetized patients during prehospital care. The study does not affect the treatment of the patient. The study is pilot study and will be followed with a main study to assess the association between cerebral oxygenation during prehospital care and outcome of the patient.
Condition or disease
Device: Near-infrared spectroscopy (NIRS) monitoring of cerebral oxygenation

Ages Eligible for Study:
18 Years and older (Adult, Older Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Critically ill or trauma patients undergoing prehospital anesthesia and endotracheal intubation for any reason by helicopter emergency medical team providing critical care.
sedation or anesthesia provided to facilitate endotracheal intubation, performed by HEMS team regardless of the reason
Cardiac arrest at the time of intubation
