Visual Alarms Alarms are indicated visually by:
The violated parameter flashes in inverse video with a
message in the status region of the display.
These visual indications remain on the display until the alarm
is corrected. Visual indication of alarms continue even when
the tones have been silenced.
Alarm Silencing If a violated parameter alarms, the tone may be silenced for
two minutes by pressing the Alarms button.
A preemptive alarm silence is provided with selectable
settings of 2, 5, 10, and 15 minutes.
Visual alarms remain on at all times.
VF/VT Alarm Automatically monitors the patient’s ECG rhythm for a
potentially shockable rhythm using the Continuous Patient
Surveillance System (CPSS). The VF/VT alarm requires that
the patient’s ECG be monitored in Lead II or Paddles lead
using therapy electrodes. The VF/VT alarm will be
suspended if pacing is enabled or Standard paddles are
connected and Paddles is the displayed lead.
Energy Shunting If the paddles input is connected in parallel with a second
defibrillator, energy delivery to the patient is reduced by less
than 10 percent.
Tall T-wave Rejection T-waves that are 1 mV high are not detected by the monitor
when the R-wave size is 1 mV and input rate is 80 ppm.
