External Pacing
Propaq MD defibrillators contain a pacemaker for the emergency treatment of
hemodynamically compromising bradycardia, bradycardia with escape rhythms that are
unresponsive to pharmacological therapy, refractory tachycardia (supraventricular or
ventricular) and bradyasystolic cardiac arrest.
Proper demand pacing requires a reliable, high quality surface ECG signal. For best results
apply both standard ECG monitoring electrodes and hands-free pacing therapy electrodes to the
patient.
Pacer Modes
The Propaq MD has two pacer mode settings: Demand and Fixed. The default factory mode
setting is Demand.
In Demand mode, pacing pulses are inhibited by the patient’s QRS complexes that occur during
an interval that is dependent on the setting of the rate control. If during that interval no QRS
complexes are detected, a pacing pulse is delivered to the patient. In the demand mode, the
pacer supplies the required number of pacing pulses to maintain the patient’s heart rate at
approximately the rate selected in the pacing rate window. See the procedure below, “Pacing in
Demand Mode” for more information.
In Fixed mode, pacing pulses are not dependent on the patient’s cardiac activity. Fixed pacing
should be performed only in an emergency when no alternative is available. The pacer delivers
pacing pulses at the selected pacing rate. See “Pacing in Fixed Mode” on page 18-6 for more
information.
Pacing in Demand Mode
Determine Patient Condition and Provide Care Following Local
Medical Protocols.
Prepare the Patient
Remove all clothing covering the patient’s chest. Dry chest if necessary. If the patient has
excessive chest hair, clip it to ensure proper adhesion of the electrodes.
1 Turn On Unit
Press the green power switch located on the top of the unit. The green, yellow, and red lights at
the top of the unit flash on and off, and the unit displays the message SELF TEST PASSED.
