A wireless noninvasive optical oxygen monitor based on near infrared spectroscopy is presented. Multi-objects (up to 20) could be monitored wirelessly by the center control system. The monitor is made of two parts. Part one is for the measurement of relative changes of oxyhemoglobin, deoxyhemoglobin and blood volume. The data from probe is transferred by GPRS Data Module. The system includes hardware for data receiving, data pre-processing, A/D converting, communication with a portable computer, and software for real time data processing. Experimental results are demonstrated.
