Welch Allyn CP 50 Plus 12-lead resting electrocardiograph - User Manual - Manual (Page 13)

WARNING To avoid serious injury or death, take these precautions during
patient defibrillation:
•
Avoid contact with the electrocardiograph, patient cable, and patient.
• Verify that the patient leads are properly connected.
• Place defibrillator paddles properly in relation to electrodes.
• After defibrillation, pull each patient lead out of the patient cable and inspect
the tips for charring (black carbon marks). If there is any charring, the patient
cable and individual leads must be replaced. If there is no charring, fully
reinsert the leads into the patient cable. (Charring can occur only if a lead is
not fully inserted into the patient cable before defibrillation.)
WARNING 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.
• Avoid ECG testing for patients with open, infectious sores.
WARNING Avoid positioning any leads or cables so that they could easily
trip someone or become wrapped around a patient’s neck.
WARNING To ensure safe use of the device, follow the documented
maintenance procedures.
WARNING Only qualified service personnel should attempt to repair the
electrocardiograph. In case of a malfunction, call Technical Support.
WARNING Do not perform ST segment analysis on the ECG screen
display, since these ECG representations are scaled. Make manual
measurements of ECG intervals and magnitudes on printed ECG reports
only.
WARNING To maintain diagnostic accuracy and to comply with IEC
60601-02-51, do not scale (re size) when sending a saved ECG to an
external printer.
WARNING To avoid injury, do not touch the print head immediately after
printing. It might be hot.
