Abstract

A patient arrhythmia monitoring system having a plurality of bedside stations that can derive physiological data for a patient coupled thereto, a central station, a bus for providing communication between said bedside stations and said central station. A processor is provided for analyzing the data from each station. Criteria for the indication of an alarm for a bedside station can be set at that station and at the central station. When an alarm is indicated for a bedside station, the data causing it can be viewed at that station as well as at the central station. Selected alarm data is temporarily stored by said processor in such manner that the data for any bedside station can be recalled at the bedside station from which it came and at the central station, A printer is provided for printing the selected alarm data for any bedside station on a separate page.

Claims

1. An arrhythmia monitoring system comprising:

at least one beside station that provides signals representing physiological data including waveforms when suitably coupled to a patient,

a central station,

means for providing communication between each bedside station and said central station,

means coupled to a bedside station for analyzing physiological data provided thereby,

means at each bedside station for setting conditions for the assertion of an alarm for that bedside station,

means at said central station for setting conditions for the assertion of an alarm at any bedside station,

alarm means coupled to each bedside station for providing an alarm signal at the bedside station and at said central station when the alarm conditions for said bedside station are met,

storage means responsive to an alarm signal for saving physiological waveform data causing said alarm,

means coupled to said storage means for displaying the physiological data causing a current alarm at the bedside station from whence the physiological data came,

means coupled to said storage means for displaying the physiological data causing a current alarm at said central station,

means at each bedside station and at said central station for eliminating at either station displayed physiological data causing the current alarm from said storage means, and

means for recording physiological data from current alarms that has not been eliminated from said storage means.

2. An arrhythmia monitoring system as set forth in claim 1 further comprising:

means coupled to said storage means for retrieving from said storage means and displaying in sequence at a bedside station and at said central station a plurality of stored physiological waveform data caused by previous alarms that have not been eliminated for any bedside station, and

means at each bedside station and at said central station for eliminating selected physiological data then displayed from said storage means, and

means for recording physiological data not eliminated.
