Other methods of communication exist now such as satellite, radio-relay,
and micro-wave systems, along with developing channels such as public
wireless LAN connections, but they all have limitations inherent to their
implementation such as cost, required training, and again coverage16.
A feasibility study by Bergrath et al17 shows a much enhanced system of
remote prehospital telemedical support is indeed feasible and does
provide a more advanced level of care for patients. In this study a centre
for teleconsultation was established and staffed by experienced
emergency medicine doctors. Selected ambulances were equipped with
telemedicine systems that included 2-way voice communication between
the paramedic and doctor via headsets, streaming video from embedded
video cameras in the ambulance, and real-time data transmitted from the
monitor / defibrillator. There was also the ability to send still photographs
from hand held smart phones to the consultation centre.
