Abstract:
1. A method of synchronizing a clock of a patient monitoring device with a clock of a central server, the method comprising: transmitting a patient data packet from the patient monitoring device to the server; receiving at the patient monitoring device an acknowledgement ACK message transmitted by the central server in response to the central server receiving the transmitted patient data packet, the acknowledgement message having a timestamp supplied from the clock of the server indicative of the time and date when the central server received the patient data packet; comparing the timestamp of the ACK message with the current time of the clock of the patient monitoring device; and if the difference between the current time of the clock of the patient monitoring device and the timestamp of the ACK message is greater than a first predetermined time, synchronizing the clock to the time and date in the timestamp in the ACK message.
