Abstract

A patient is monitored using a monitoring apparatus including a remote monitoring unit associated with the patient and having a sensor that measures a physiological characteristic of the patient, a central unit, and a communications device which selectively establishes a communications link between the remote monitoring unit and the central unit. The remote monitoring unit obtains a monitored data set for the patient, analyzes the monitored data set to obtain a derived data set from the monitored data set, and determines from the derived data set that communication with the central unit is required. A communications link is established with the central unit, and the remote monitoring unit transmits to the central unit an initially transmitted data set related to the monitored data set. The central unit analyzes the initially transmitted data set and instructs the remote monitoring unit as to any additional transmitted data set related to the monitored data set that is to be transmitted from the remote monitoring unit to the central unit and a time at which the additional transmitted data set is to be transmitted.

Description

[0001] This invention relates to the transmission of data between a remote monitoring unit and a central unit, and more particularly to the optimization of such data transfer.BACKGROUND OF THE INVENTION

[0002] Advances in sensor technology, electronics, and communications have made it possible for physiological characteristics of patients to be monitored even when the patients are ambulatory and not in continuous, direct contact with a hospital monitoring system. For example, U.S. Pat. No. 5,959,529 describes a monitoring system in which the patient carries a remote monitoring unit with associated physiological sensors. The remote monitoring unit conducts a continuous monitoring of one or more physiological characteristics of the patient according to the medical problem of the patient, an example being the heartbeat and its waveform.

[0003] Under prescribed conditions, the remote monitoring unit contacts a central unit to communicate information on the condition of the patient. For examp...
