Pre-shock CPR Time
When
PRE-SHOCK CPR
time is set to 15 seconds or more, you are prompted to start CPR
immediately after a shockable rhythm is detected, before the shock is delivered.
After analysis is complete, the
START
CPR
prompts occur. A countdown timer
(min:sec format) continues for the duration
specified in the
PRE-SHOCK CPR
time
setup option.
The defibrillator silently charges in
preparation for the shock.
When CPR time ends, the
SHOCK
ADVISED
and
STAND CLEAR, PUSH
SHOCK BUTTON!
( ) prompts occur.
Proceed according to your training with
the AED for delivering a shock.
Note:
The (shock) button is disabled during the pre-shock CPR interval to avoid
accidental shock delivery while the defibrillator is charged and a responder is performing
CPR.
Advisory Monitoring
Advisory Monitoring is a special way to set up AED mode that allows the use of all the
monitoring functions without initiating the AED prompted protocol when the device is turned
on. When needed, the AED mode prompted protocol can be initiated by pressing
ANALYZE
.
In addition, access to Manual mode therapies—that is, manual defibrillation, synchronized
cardioversion, or pacing—by unauthorized users can be restricted, if necessary.
Certain setup options must be changed for the device to operate in Advisory Monitoring
when it is turned on. For more information, see the
LIFEPAK 15 Monitor/Defibrillator Setup
Options
provided with your device.
When set up for Advisory Monitoring and the monitor is turned on, the
ADVISORY MODE-
MONITORING
message appears continuously in the message area on the Home Screen.
Monitor functions such as NIBP, SpO
2
and 12-lead ECG can be used. Lead II and dashes are
shown in the top ECG trace (Channel 1) unless or until the patient is connected to the ECG
cable. If therapy electrodes (pads) and the therapy cable are connected to the patient, press
LEAD
to change to
PADDLES
lead and view the ECG.
In Advisory Monitoring,
LEAD II
and
PADDLES
lead are the only ECG monitoring leads allowed
in Channel 1. The Continuous Patient Surveillance System (CPSS) is active and automatically
evaluates the patient ECG. However, CPSS is evaluating only for a potentially shockable
rhythm. If a shockable ECG rhythm such as VF is detected, the following prompt appears:
CHECK PATIENT. IF NO PULSE, PUSH ANALYZE
.
Prior to pressing
ANALYZE
, confirm that the patient is in cardiac arrest. Motion artifact, a low
amplitude ECG, and other causes of poor ECG signal may cause false CPSS alerts. If the
patient is not in cardiac arrest, do not press
ANALYZE
. Troubleshoot the cause of the false
CPSS alert.
If the patient is in cardiac arrest, press
ANALYZE
. Pressing
ANALYZE
causes the defibrillator
to enter AED mode. The defibrillator begins the AED prompted protocol and analyzes the
