Safety and Precautions
Caution
Radio Frequency (RF) interference between the PRO ECG Recorder or
cardiograph and any existing RF transmitting or receiving equipment at
the installation site, including electrosurgical equipment, in close
proximity to the cardiograph should be evaluated before the equipment is
operated as they may seriously degrade performance.
The CardioPerfect Cardiograph is susceptible to interference from RF
energy sources (lowered RF immunity) which exceed the IEC 60601-1-2
limits, such as power line bursts, other medical devices, cellular products,
information technology equipment and radio/television transmission.
To reduce EMC interference the cardiograph shall be separated from the
emitting source as much as possible. If assistance is needed, call your
local Welch Allyn service representative.
Artifact on the ECG caused by electromagnetic interference should be
evaluated by a physician or physician authorized personnel to determine
if it will negatively impact patient diagnosis or treatment.
Like all electronic devices, this cardiograph is susceptible to electrostatic
discharge (ESD). Electrostatic discharge typically occurs when
electrostatic energy is transferred to the patient, the electrodes, or the
cardiograph. ESD may result in ECG artifact that may appear as narrow
spikes on the cardiograph display or on the printed report. When ESD
occurs, the cardiograph’s ECG interpretation may be inconsistent with
the physician’s interpretation.
Welch Allyn assumes no liability for failures resulting from RF
interference between Welch Allyn medical electronics and any radio
frequency generating equipment when these levels exceed those
established by applicable standards.
Patient cables and PC connection cables are intended to be inserted and
removed from the PRO ECG Recorder in a push / pull motion. Do not
twist the cables. Damage to the cables and the PRO ECG Recorder will
occur.

DIR 80012763 Ver. H4 / 25
Warnings
Power strips (multiple portable socket outlets) are not allowed for use
in connecting the medical electrical equipment or any accessories to
ground unless used in concert with a medical approved isolation
transformer.
During defibrillation, the ECG signals displayed may show waveform
artifacts and cannot be relied on as a true indication of the patient’s
physical condition.
Accessible metal parts, such as electrode terminations, should not
come in contact with other electrically conductive parts, including earth
ground.
Welch Allyn provides a number of high quality patient leads in varying
termination styles. Use of these approved patient leads is required for
electrical protection of the patient during cardiac defibrillation.
CardioPerfect devices are not intended for direct cardiac application.
An inoperable or damaged electrocardiograph can be identified by
abnormal signals on the ECG waveforms. Abnormal signals are
characterized by flat lines, excess noise, square waves or other non
typical anomalies that appear on the ECG waveform. The
electrocardiograph can be periodically tested by connecting the
CardioPerfect to an ECG simulator. Follow manufacturer’s
instructions.
If there is a requirement for equipment to be connected to a personal
computer or other non-medical rated equipment, it is the responsibility
of the user to ensure that the electric power circuit to which the
CardioPerfect system is connected includes an additional protective
earth ground or an isolation transformer in order to satisfy the IEC
60601-1 safety standard.
Other medical equipment—including but not limited to defibrillators,
ultrasound machines, pacemakers, and other stimulators—may be
used simultaneously with the electrocardiograph. However, such
devices may disturb the electrocardiograph signal.
The electrocardiograph has not been designed for use with high
frequency (HF) surgical equipment and does not protect against
hazards to the patient.
Fire and explosion hazard. Do not operate the electrocardiograph in
the presence of a flammable anesthetic mixture with air, oxygen, or
nitrous oxide; in oxygen-enriched environments; or in any other
potentially explosive environment.
To prevent the spread of infection, take these precautions:
•Dispose of single-use components (for example, electrodes)
after using them once.
•Regularly clean all components that come in contact with
patients.
•Consult your facility's equipment cleaning procedures when
performing ECG testing on patients with open, infectious
sores.

CardioPerfect
PRO ECG Recorder - User Manual
DIR 80012763 Ver. H5 / 25
Ensure the location of the electrode and associated cables provides
maximum separation away from all sources of high-frequency energy.
The best way to ensure patient safety is to completely remove all
electrodes and cables from the patient when exposed to high-
frequency energy.
No modification of this equipment is allowed.

DIR 80012763 Ver. H6 / 25
Patient and Operational Safety
The cardiograph isolates all connections to the patient from electrical ground and all other
conductive circuits in the cardiograph. This reduces the possibility of hazardous currents
passing from the cardiograph through the patient’s heart to ground. To ensure the patient’s
safety and your own please observe the following:
When integrating CardioPerfect devices with non-medical rated equipment, such as a
computer, the addition of an additional protective earth ground or the use of a medically
approved isolation transformer is required for compliance to the IEC 60601-1 Medical System
Safety Standard.
Any system components (e.g. treadmill, personal computer, ergo meter) that require to be
connected to an outlet socket shall use only grounded power cords (three-wire power cords
with grounded plugs). Also make sure the outlet accepts the plug and is grounded. Never
adapt a grounded plug to fit an ungrounded outlet by removing the ground prong or ground
clip.
Do not connect Multiple Portable Socket Outlets (MPSO’s) or extension cords to the system.
Do not connect items which are not part of the system. The use of multiple portable socket
outlets and other non-medical electrical equipment poses a safety hazard. Refer to the
Medical System Safety Standard IEC 60601-1 for the requirements of such attachments.
Multiple portable outlet sockets shall not be placed on the floor. Multiple portable outlet
sockets or extension cord shall not be connected to the system. Do not connect items which
are not part of the system. The use of multiple (non-) medical electrical equipment connected
to the same patient may pose a safety hazard due to the summation of leakage currents from
each instrument. Any combination of (non-) medical electrical equipment should be evaluated
by local safety personnel before put into service. Multiple portable outlet sockets use without
an isolation transformer is disapproved unless casual access for additional equipment is
impeded or prevented.
Accessories
Use of accessories other than those recommended by Welch Allyn may compromise product
performance. The Welch Allyn warranty can only be honored if you use Welch Allyn approved
accessories and replacement parts.

1.About the CardioPerfect PRO Cardiograph
The Welch Allyn CardioPerfect PRO Cardiograph is specifically intended for the recording of
standard 12-lead electrocardiograms of patients. The device is not suitable for direct cardiac
application.
A CardioPerfect PRO system typically comes with the following components:
CardioPerfect PRO Cardiograph (SE-PRO-600, -1200)
Patient Cable (RE-PC or SE-PC)
PC Interface Cable Prolink (PRO-60023, -24, -25)
CardioPerfect Workstation Software (CPWS-SW)
Caution
The patient cable supplied with the CardioPerfect cardiograph is an
integral part of the cardiograph’s safety features. Using any other
patient cable may compromise defibrillation protection as well as
cardiograph performance. The patient cable should be routed away
from power cords and any other electrical equipment. Failure to do
so can result in AC power line frequency interference on the ECG
trace.
Warning
Do not touch the patient, patient cable, PC interface cable (Prolink)
or cardiograph during defibrillation. Death or injury may occur from
the electrical shock delivered by the defibrillator. It is recommended

3. Maintenance
Clean the equipment
Warning
Keep the PRO ECG Recorder, reusable electrodes, and the patient
cable clean. Patient contact with contaminated equipment can
spread infection.
The patient cables should be cleaned after each use and disinfected
as needed.
Caution
Never immerse the PRO ECG Recorder or the patient cable in
liquid. Never autoclave or steam clean the PRO ECG Recorder or
the patient cable. Never pour alcohol directly on the PRO ECG
Recorder or the patient cable, and never soak any components in
alcohol. If any liquid enters the PRO ECG Recorder, remove the
PRO ECG Recorder from service, and have it inspected by a
qualified service person before using it again.
Clean the PRO ECG Recorder
Unless the PRO ECG Recorder (the device itself rather than the cables and electrodes)
comes in direct contact with a patient, it is acceptable to clean the device on a routine basis
according to your facility's protocols and standards or local regulations. Patient contact with
the device might require immediate cleaning.
The following agents are compatible with the PRO ECG Recorder:
•70 percent isopropyl alcohol
•10 percent chlorine bleach solution
Caution
When cleaning the device, avoid using cloths or solutions that
include quaternary ammonium compounds (ammonium chlorides)
or glutaraldehyde-based disinfectants.
1. Slightly dampen a soft, clean cloth with an acceptable
cleaning solution, or use a 70 percent alcohol pad to wipe the
exterior of the PRO ECG Recorder. Dry all components with a
clean, soft cloth or paper towel.
2. Before you power on the PRO ECG Recorder again, wait at
least 10 minutes for all traces of liquid to evaporate.
