Procedure alarm silence feature for medical telemetry system
First Claim
1. In a system in which physiologic data of a patient is sensed and transmitted to a monitoring station by an ambulatory telemeter unit worn by the patient, and in which the monitoring station analyzes the physiologic data in real time to check for alarm conditions, a method of remotely disabling an alarm of the monitoring station, comprising:
- detecting a predefined user action performed on the ambulatory telemeter unit worn by the patient; and
responding to detection of the predefined user action by transmitting a message from the ambulatory telemeter unit to the monitoring station to cause the monitoring station to preemptively disable an alarm at the monitoring station for a preprogrammed time period, to thereby inhibit false alarms as a procedure is performed on the patient.

Abstract
A medical telemetry system includes a procedure alarm silence feature that enables a clinician to remotely disable a monitoring station alarm in order to perform a patient procedure that might cause inadvertent false alarms. To disable the alarm for a preprogrammed time interval, the clinician presses keys on the telemetry unit according to a predefined key sequence that is selected so as to reduce a likelihood of accidental alarm disablement. The monitoring system responds to the predefined sequence by disabling an audible alarm for all alarm conditions except class 1 arrhythmias. A corresponding visual alarm at the monitoring station is maintained active. While the alarm is disabled, the monitoring station displays an indication of the amount of time until expiration of the preprogrammed time interval.

13. A medical telemetry system, comprising:
-
an ambulatory telemeter unit that senses and transmits physiologic data of a patient in real time, the ambulatory telemeter unit configured to be worn by the patient; and
a monitoring system that receives and displays the physiologic data transmitted by the ambulatory telemeter unit, and analyses the physiologic data to check for at least one type of alarm condition;
wherein the monitoring system is responsive to a predefined user action performed on the ambulatory telemeter unit by preemptively disabling an alarm associated with the ambulatory telemeter unit for a preprogrammed time interval, so that a clinician can remotely disable the alarm while performing a procedure on the patient. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 31, 32)

24. A telemeter unit, comprising:
-
a housing having a plurality of keys;
a lead set that attaches to a patient to sense physiologic data of the patient, wherein the telemeter unit is configured to transmit the physiologic data to a remote monitoring station; and
a processing module which is responsive to a predefined sequence of depressions of the keys by transmitting an alarm silencing message to the remote monitoring station to cause the remote monitoring station to preemptively disable an alarm associated with an automated analysis of the physiologic data, the predefined sequence of depressions selected to reduce a likelihood that the alarm will be disabled by accident. - View Dependent Claims (25, 26, 27, 28)

33. A medical telemetry system, comprising;
-
an ambulatory telemeter unit that senses and transmits physiologic data of a patient in real time, the ambulatory telemeter unit configured to be worn by the patient; and
a monitoring system that receives and displays the physiologic data transmitted by the ambulatory telemeter unit, and analyses the physiologic data to check for at least one type of alarm condition;
wherein the telemetry system is responsive to a predefined user action performed on the ambulatory telemeter unit by disabling an alarm associated with the ambulatory telemeter unit prior to an expected alarm condition for a preprogrammed time interval, so that a clinician can remotely disable the alarm while performing a procedure on the patient.
