Noninvasive Pacing

LIFEPAK 15 Monitor/Defibrillator Operating Instructions
OBSERVATION POSSIBLE CAUSE CORRECTIVE ACTION
No muscle response to
pacing
Patient’s heart rate may be
greater than noninvasive pacer
ppm
•
No action needed.
The Test Load is connected to
therapy cable
•
Remove the Test Load and
connect therapy electrodes to
cable.
Patient muscle response is
variable and depends on patient
condition. Muscular response to
pacing is not a reliable indicator
of current delivered.
•
No action needed.
Capture does not occur with
pacing stimulus
Current (mA) set too low •
Increase pacing current.
(Administer sedation or
analgesia as needed.)
CONNECT CABLE
or
PACING
STOPPED message appears
Therapy cable damaged
• Replace therapy cable and
perform daily checks per
Operator’s Checklist.
CONNECT ELECTRODES
message appears
Pacing cable or electrode
disconnected
• Reconnect and set current.
Electrodes not adhering to skin • Prepare skin.
Therapy cable damaged •
Replace therapy cable and
perform daily checks per
Operator’s Checklist.
Electrodes outdated •
Replace electrodes and set
current.
PACING IN PROGRESS
message appears
CPR pressed •
Press PACER to stop pacing,
if appropriate, and then press
CPR .
Pacing stops spontaneously
and PACER FAULT message
appears
Internal error detected
• Cycle power and start pacing
again.
•
Obtain service by a qualified
service technician.
Intrinsic QRS complexes not
sensed when pacing
ECG size too low •
Increase ECG size or select
another lead.
Intrinsic QRS complexes are
occurring during pacemaker's
refractory period
• Adjust PPM.
Pacing starts spontaneously Patient’s heart rate falls below
set pacing rate
• Appropriate pacemaker
function; assess patient.
During standby pacing, ECG
lead disconnects and pacing
begins asynchronously
•
Reconnect ECG lead.
Set pacing rate (ppm) and
ECG paced rate do not
appear to match
Internal error detected •
Print ECG and calculate the
pace rate.
Improper sensing
(for example, sensing on
T-waves)
QRS complex too small •
Select another lead.
T-wave too large • Adjust ECG size.
