Introduction Important Patient and Safety Information
Important Patient and Safety Information
The PageWriter TC70 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.
WARNING Failure to follow these warnings could affect both patient and operator safety.
Accessories and Supplies
WARNING Always clean and disinfect reusable electrodes before patient use. Failure to properly
clean and disinfect reusable electrodes before patient use may cause infectious materials
to be transferred between patients.
WARNING The Welsh bulb electrodes (available as an accessory for the cardiograph) do not meet
the requirements of IEC 60601-2-25 for defibrillation recovery time, and cannot be
reliably used for patient diagnosis immediately following defibrillation.
WARNING When using additional peripheral equipment powered from an electrical source other
than the cardiograph, the combination is considered to be a medical system. It is the
responsibility of the operator to comply with IEC 60601-1-1 and test the medical system
