f. General Safety Precautions. Ensure that the following precautions are
followed when operating the defibrillator.
Select the proper voltage for either 110v or 220v.
Stand clear of the patient during defibrillation procedures.
(3) Do not use the MRL Porta Pak 90 defibrillator and cardiac monitor in the
presence of anesthetics or flammable material.
(4) Keep defibrillator paddles clean and dry when not in use. When preparing
electrodes and during defibrillation procedures, exercise extreme care to prevent gel or any
conductive material from forming a contact between the operator and the paddles.
(5) Use only MRL patient cables or those that meet AAMI patient cable and
Pacemaker Patients. Rate meters may continue to count the pacemaker
rate during some occurrences of cardiac arrest or some arrhythmias. Do
not rely upon rate meter alarms. Keep pacemaker patients under close
Section II. CALIBRATION AND VERIFICATION
CALIBRATE AND VERIFY THE POWER SUPPLY/DEFLECTION OF THE
In addition to PMCS, you are also responsible for performing calibration and
verification procedures. In this section you will learn how to calibrate the MRL Porta Pak
90 to ensure its safe use during surgery. When you calibrate the defibrillator/monitor, you
verify its output against a known standard. If the unit fails calibration, you must repair it
before returning it to service. Refer to paragraph 1-3 for general safety precautions.
a. Access the Monitor Main Circuit Board. To calibrate the monitor, you must
access the main circuit board. Remove the monitor chassis from the base. Follow the
procedures in paragraph 1-3.b. Rotate the monitor into an upright position (figure 1-10).
