Med-Com is one half of airlife. you have Flight-Com and Med-Com if you ever hear of a patient being Med-Comm'd is when trauma is involved. Med-Com will activate and locate the nearest trauma center and make sure the necessary resources are available. What would normally take 2-3 hours is cut to 1 through Med-Com facilitating the consolidated information for expedited treatment.
Long story short AirLife tone out which is rarely used since many of the locations are withing San Antonio proper.
Hope that helps
