NOTE: Arrhythmia alarms are not available for the Neonate
patient size.
4.4.1 Lethal Arrhythmia Alarms
A lethal arrhythmia is an arrhythmia that can be life threatening to a patient if left untreated.
Ventricular Tachycardia (V-Tach), Ventricular Fibrillation (V-Fib), and Asystole alarms are
classified as lethal arrhythmia alarms. These alarms automatically default to Alarm Priority 1.
NOTE: Lethal arrhythmia alarms may be configured to have a
different alarm sound than other physiological alarms. The
sounds used are determined during system setup and
configuration.
NOTE: Lethal arrhythmia alarms are latched alarms and must be
acknowledged after the condition is resolved. To
acknowledge the alarm, select the digital data area or the
waveform area of the affected patient tile.
NOTE: If a lethal arrhythmia alarm condition exists, and a
transition to a different lethal arrhythmia alarm condition
occurs, a new event will be stored and a printout will be
generated, as configured.
NOTE: When a V-Tach or V-Fib alarm occurs and is replaced by an
Asystole alarm, the Asystole alarm will be paged. This will
occur if Paging has been installed on the central station; the
Asystole alarm paging delay timer has expired; and the
alarm condition still exists when the paging delay timer has
expired.
Asystole Alarm
An Asystole alarm is activated at the Panorama Central Station when no QRS complexes
are detected for the configured time period in the absence of Ventricular Fibrillation. When
using a View 12
™
card, the time period range for an Asystole alarm is between three (3)
and eight (8) seconds. When using a 3 or 5-wire lead set, the time period range for an
Asystole alarm is between three (3) and ten (10) seconds.
The Asystole alarm is a Priority 1 alarm event that:
• Produces an Alarm Priority 1 visual and audio alarm indicators once the condition is
identified.
• Causes a red Asystole text message to display in the Patient Status line.
Ventricular-Fibrillation (V-Fib) Alarm
A V-Fib alarm is activated at the Panorama Central Station when a fibrillated waveform (P,
QRS or T waves can no longer be identified) is detected. V-Fib is defined as “irregular,
disorganized electrical activity of the heart”. The ECG signal for V-Fib continuously changes
shape, interval, and amplitude. The V-Fib detection algorithm runs in parallel to the beat
detection algorithm and continuously examines the incoming data.
The V-Fib alarm is a Priority 1 alarm event that:
• Produces Alarm Priority 1 visual and audio alarm indicators once the condition is
identified.
