Technological Evolution in Helicopter Emergency Medical Services

To make best result in HEMS (helicopter emergency medical system), we have to bring The right patient, to the right place, at the right time, with right medical care.
So how can we accomplish these?
In traditional helicopter emergency medical systems, helicopters start to move after reports from witnesses of the accident or emergency medical teams. Under this system, it takes about 38 minutes from the occurrence of an accident to the start of medical care according to the researches in Japan.
To shorten this time, the advanced automatic collision notification service called "D-Call Net" has been introduced in Japan.
In this system, sensors attached to the car send the location data and the impact at the time of the collision to the server. The severity of the patient is calculated automatically and will be sent to the HEMS base.
With this system, the time to start advanced medical care shortened by 17 minutes.
In addition, a system called REMOTE (REal-time MOvie Transmission system using smart phone for EMS), which transmits real-time images to medical institutions from smartphones used by medical crews, is under development.
Based on this information, HEMS bases can send accurate instructions to medical crews, and hospitals that accept patients can make preparations.
These new technologies will be the “Game Changer” in the HEMS world.
