Ecg Monitoring - ZOLL Propaq MD Operator's Manual

C 1 G I
HAPTER ENERAL
The use of accessories, transducers, and cables other than those specified in this manual and
related Propaq MD option manual inserts may result in increased emissions or decreased
immunity of the Propaq MD.
Perform functional test of internal paddles prior to use.
Do not use or place the unit in service if the Ready For Use indicator (at the upper right of the
front panel) displays a red circle with a line through it.
Carefully route patient cables to avoid tripping over them, or inadvertently pulling the unit onto
the patient.
Always inspect the unit for damage if it has been dropped.
Only authorized personnel should use the Supervisor menus.
If uncertain about the accuracy of any measurement, first check the patient's vital signs by
alternate means, and then make sure the monitor is functioning correctly.

ECG Monitoring

Implanted pacemakers might cause the heart rate meter to count the pacemaker rate during
incidents of cardiac arrest or other arrhythmias. Dedicated pacemaker detection circuitry may
not detect all implanted pacemaker spikes. Check the patient's pulse; do not rely solely on heart
rate meters. Patient history and physical examination are important factors in determining the
presence of an implanted pacemaker. Pacemaker patients should be carefully observed. See
"Pacemaker Pulse Rejection:" on page A-15 of this manual for disclosure of the pacemaker
pulse rejection capability of this instrument.
Use only ECG electrodes that meet the AAMI standard for electrode performance
(AAMI EC-12). Use of electrodes not meeting this AAMI standard could cause the ECG trace
recovery after defibrillation to be significantly delayed.
Prior to attempting synchronized cardioversion, ensure the ECG signal quality is good and that
sync markers are displayed above each QRS complex.
Do not place electrodes directly over an implanted pacemaker.
The Propaq MD unit detects ECG electrical signals only. It does not detect a pulse (effective
circulatory perfusion). Always verify pulse and heart rate by physical assessment of the patient.
Never assume that the display of a nonzero heart rate means that the patient has a pulse.
Excessive artifact can result due to improper skin preparation of the electrode sites. Follow skin
preparation instructions in Chapter 6: "Monitoring ECG."
Do not operate the Propaq MD in conjunction with electrocautery or diathermy equipment.
Such equipment, as well as equipment that emits strong radio frequency signals, can cause
electrical interference and distort the ECG signal displayed by the monitor, thereby preventing
accurate rhythm analysis.
Shock Hazard: Use of accessories, other than those specified in the operating instructions, may
adversely affect patient leakage currents.
Certain line-isolation monitors may cause interference on the ECG display and may inhibit
heart rate alarms.
Monitoring ECG through the paddles may result in inaccurate heart rate display due to artifact.
