Descriptive Information
Brief Title Brain Oxygenation During Prehospital Anesthesia
Official Title Brain Oxygenation During Prehospital Anesthesia: an Observational Pilot Study
Brief Summary 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.
