Abstract

A system for monitoring a physiological condition of a patient includes a primary station and a portable station. The primary station includes a transmitter configured to transmit a signal, which represents a physiological condition of the patient, via a wireless communication link. The portable station includes: a receiver configured to receive the signal, via the wireless communication link, from the primary station; a display configured to display, based upon the signal, a representation of the physiological condition to a user, and an alarm exhibitor configured to exhibit an alarm indication to the user in response to an identified anomaly in the physiological condition of the patient. The alarm exhibitor may be configured to exhibit the alarm indication in response to an alarm signal received, via the wireless communication link, from the primary station. The portable station may include a transmitter adapted to communicate, via the wireless communication link, with the primary station to permit the user to respond to the alarm indication.
