(57) ABSTRACT
A device and method for monitoring a patient having a sensing device taking sensor data continuously and a transmitter located on the patient and internally powered. The transmitter is normally in a power-down state and powered-up for transmitting the sensor data. A receiver is located remote from the patient and receives the sensor data transmitted wirelessly from the transmitter. The transmission is typically a burst and can also be initiated on a command. For the burst, the sensor data is accumulated over a first period. The transmitter can transmit the sensor data over a second period of time. The second period of time is shorter than the first period of time. Once the transmission is complete, transmitter can be powered down. A further step displays the sensor data at the receiver in pseudo real-time. The display is shifted by a sum of the first and the second period of time.
