Arrhythmia Monitoring - Philips M3150B Installation And Service Manual

•
Figure 1-11 shows a typical Main Screen with patients in alarm. Note that Patient Sector
CCU2 has the alarm message ***TACHY 160>140. Patient Sectors in alarm are backlighted
in blue for easy identification, and the alarm message window is backlighted in the color of
the alarm severity. For example, the CCU2 message shows a red alarm (***) message.
Table 1-8 summarizes the various alarms that can occur, including the corresponding alarm
sound, alarm message location, ECG recording generation, and alarm meaning. Alarm
messages are described in the IntelliVue Information Center Instructions for Use.

Arrhythmia
In addition to patient monitoring, the Information Center system provides arrhythmia
Monitoring
monitoring for both bedside and telemetry monitored patients. The multi-lead arrhythmia
monitoring algorithm is designed for adult, pediatric, and neonatal patient ECG waveforms
ECG recording is generated for preset periods preceding and following the alarm
event (Red and Yellow alarms only)

Introducing the IntelliVue Information Center System
Clinical Applications
Life threatening, e.g.
AYSTOLE
non-arrhythmia alarm limit
violation (except for HR,
which is an Arrhythmia
alarm)
Arrhythmia yellow alarm
detected
Nurse Call button on
telemetry transmitter
depressed and system
configured to alarm
Inoperative condition that
prevents monitoring, e.g.
LEADS OFF, or has direct
effect on the patient, e.g.
NBP CUFF OVERPRESS
Inoperative condition that
prevents signal processing,
e.g., NOISY ECG.
Monitoring continues during
this INOP condition.
