Wireless acquisition system for the real ambulance field

In this paper we present a novel wireless acquisition system for the real ambulance field which could be equipped on ambulance vehicle to realize pre-hospital treatment for patients. The distinctive feature of the system is that it can not only provide biomedical information including the oxygen saturation, the ECG, the blood pressure, the temperature and the heart rate of patients, but also supply an interactive multimedia communication module including audio and video information. Several important techniques, e.g., the wireless sensor network, the audio and video compression and the CDMA telecommunication module, will be discussed in this paper.
