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-3 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.
Do not place electrodes directly over an implanted pacemaker.
The Propaq M 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 M 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.
Pulse Oximeter
Keep the ZOLL finger probe clean and dry.
SpO
2
measurements may be affected by certain patient conditions: severe right heart failure,
tricuspid regurgitation or obstructed venous return.
SpO
2
measurements may be affected when using intravascular dyes, in extreme
vasoconstriction or hypovolemia or under conditions where there is no pulsating arterial
vascular bed.
SpO
2
measurements may be affected in the presence of strong EMI fields, electrosurgical
devices, IR lamps, bright lights, improperly applied sensors; the use of non-ZOLL sensors, or
damaged sensors; in patients with smoke inhalation, or carbon monoxide poisoning, or with
patient movement.
Tissue damage can result if sensors are applied incorrectly, or left in the same location for an
extended period of time. Move sensor every 4 hours to reduce possibility of tissue damage.
Do not use any oximetry sensors during MRI scanning. MRI procedures can cause conducted
current to flow through the sensors, causing patient burns.
