Mobile ER/ICU

The staff, medical equipment and medications on board make Mayo One Helicopter a mobile emergency room (ER) equipped to handle nearly any patient with serious trauma injuries or who is critically ill. Onboard equipment allows the flight team to monitor a patient's heart rate, blood pressure, temperature, and carbon dioxide and oxygen levels. The flight team uses external defibrillators, external pacemakers and other advanced-level equipment. All Mayo One helicopters carry a portable lab analyzer that measures the patient's arterial or venous blood gases and other lab values. Mayo One Helicopter crews follow a physician-directed protocol for initiating therapeutic hypothermia in select cases. Blood (three units) and thawed plasma (three units) are carried on every flight and can be administered inflight or at the referring hospital. Mayo One Helicopter crews also carry tranexamic acid (TXA).

Mayo One Helicopter crews began using TXA for eligible patients on July 9, 2012, when published data indicated it was beneficial for the trauma patient if given within three hours of injury. It is also approved for use in select patients who experience a medical head bleed. Mayo Clinic's blood administratin guidelines call for the use of TXA for these patients when they meet criteria for pre-hospital administration of blood products.
