A finger oximeter has fitted thereto a RF transmitter circuit so that the measured SpO2, and other physical parameters from a patient, may be transmitted telecommunicatively to a monitor device remotely located from the finger oximeter. The RF transmitter circuit is mounted on a PC board that is provided in the housing of the finger oximeter, and works in cooperation with the oximetry circuit that is also mounted on a PC board in the housing of the finger oximeter. The two PC boards may be combined as one. To receive the RF signal, a RF receiver is provided to the remote monitor device, which also includes a processing circuit for processing the incoming RF signal, and a converter circuit for converting the processed digital signal into an analog signal for display at the remote monitor device. In place of a one-way RF link, the finger oximeter may be equipped with a RF transceiver circuit that is capable of transmitting as well as receiving RF signals from the remote monitor device, which likewise is fitted with a RF transceiver circuit. The finger oximeter could be activated by the patient manually, by means of a switch provided at the housing, or remotely by means of a signal provided from the remote monitor device. The finger oximeter may or may not include a display.
