Ambulances with Med Care EMS in McAllen are equipped with blood on hand that can be used to perform potentially life-saving transfusions on patients before they arrive at the hospital. Clinical Coordinator with Med Care EMS Richard Becerra says they respond to trauma-related calls daily, so having O-positive blood on board allows them to better care for patients who desperately need a transfusion.
