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:
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.
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.
Patient cable and Interface cable
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 to
check the patient cable and PC interface cable (Prolink) for damage
prior to the use of the system. If damage exists do not use the cable,
contact your local Welch Allyn Sales Office or your authorized Welch
Allyn dealer or distributor to have the cable replaced.
