A new channel assignment system of bedside monitor and telemetry

−Enabling free monitor movements between wards without channel change−

Abstract

Patient information from bedside monitors (monitor), such as electrocardiogram, blood pressure and the oxygen saturation in blood, has been sent to telemetry central monitor (receiver) in the nurse station by radio. When number of monitors are short due to an increase in the patient number requiring monitor, central dispatching is desired to manage the monitors. However, in case monitors are moved between wards, radio frequency (channel) must be changed to avoid interference because monitors are used on wireless base. Therefore, we devised a new system in term of monitor management. This is an ideal system that avoids interference even without changing channels between wards. This method also saves operation time and cost. We report newly-devised method and its benefit.
