ECG-related Information
WARNING
■ This device is not intended to provide a primary ECG monitoring
function, and therefore does not have means of indicating an
inoperative electrocardiograph.
■ Do not use ECG electrodes with HF surgical equipment. HF surgical
equipment may be damaged, which may result in fire.
■ Do not use ECG electrodes during cardiac pacemaker procedures or
any procedures that involve other types of electrical stimulators.
■ Do not use ECG leads and electrodes in an operating room.
ESD
Electrostatic discharge (ESD), commonly referred to as a static shock, is a naturally occurring
phenomenon. ESD is most prevalent during conditions of low humidity, which can be caused by
heating or air conditioning. The static shock, or ESD, is a discharge of the electrical energy
build-up from a charged individual to a lesser or uncharged individual or object. An ESD occurs
when an individual with an electrical energy build-up comes in to contact with conductive objects
such as metal doorknobs, file cabinets, computer equipment, and even other individuals.
CAUTION
■ The level of electrical energy discharged from a system user or patient to
an ultrasound system can be significant enough to cause damage to the
system or probes.
■ Always perform the pre-ESD preventive procedures before using
connectors marked with the ESD warning label.
- Apply anti-static spray to carpets or linoleum.
- Use anti-static mats.
- Ground the product to the patient’s table or bed.
■ It is highly recommended that the user be given training on ESD-related
warning symbols and preventive procedures.
