Alarms; Physiological Alarm Summary - Welch Allyn Connex ECG Module Directions For Use Manual

Alarms

The Connex device displays physiological and technical alarms triggered by the ECG/
Impedance Respiration module. Physiological alarms occur when vital sign
measurements fall outside of set alarm limits. Technical alarms occur when there is the
problem with the module, an accessory connected to the module, the Connex device, or
the network. The module can communicate alarms to the monitor and an external Nurse
Call, if available, in the Continuous Monitoring profile. Technical alarms occur in all
profiles.
See the Welch Allyn Connex® Devices directions for use for detailed descriptions of
alarm behavior, controls, and messages.
