Noninvasive Pacing Warnings
Demand and Nondemand Pacing
The noninvasive pacemaker can be used for either demand (synchronous) or nondemand
(asynchronous) pacing modes.
The demand mode is used for most patients. In the demand mode, the LIFEPAK 20e defibrillator/
monitor/pacemaker inhibits pacing when it senses the patient’s own beats (intrinsic QRSs). In
demand mode, if the ECG amplitude is too low to detect the patient’s beats, or if an ECG lead
becomes detached so that the ECG rhythm is not present, the pacemaker generates pacing
pulses asynchronously. This means that the pacemaker generates pacing pulses at the selected
rate, regardless of the patient’s ECG rhythm.
Asynchronous or nondemand mode can be selected if noise or artifact interferes with proper
sensing of QRS complexes. Press the
OPTIONS button to access the nondemand mode. (Refer
to page 2-7 .)
WARNINGS!
Possible inducement of ventricular fibrillation.
Sinus bradycardia may be physiologic in severe hypothermia (i.e., appropriate to maintain
sufficient oxygen delivery when hypothermia is present), and cardiac pacing is usually not
indicated.
Possible interruption of therapy.
Observe the patient continuously while the pacemaker is in use. Patient response to pacing
therapy, e.g., capture threshold, may change over time.
Possible inability to pace.
Using other manufacturers’ combination therapy electrodes with this device could cause a
decrease in pacing efficacy or the inability to pace because of unacceptably high impedance
levels.
Possible patient skin burns.
Prolonged noninvasive pacing may cause patient skin irritation and burns, especially with higher
pacing current levels. Discontinue noninvasive pacing if skin becomes burned and another
method of pacing is available.
