A study on nationwide emergency medical network for ambulances via HEOs

We have studied specifications for satellite transponder to perform nationwide emergency medical network for ambulance over Japan. If it is possible to send in real-time a large volume of biological data (such as when a thrombolytic dose is administered to a patient suffering acute cardiac infarction being conveyed in an ambulance, based on his or her 12 leads electrocardiogram data and cardio-echogram with compressed motion picture, for early treatment for removal of a coronary occlusion) and color video images (such as light reflex images and video images of the airway) from an ambulance to a triage center to receive instructions from a doctor, more patients will be saved and medical expenditures for emergency medicine will ultimately be reduced. We investigate required specifications as follows; 1) channels, 2) bandwidth, 3) frequency, 4)footprints, 5) technical limitations of the transponder others.
