2.3.2. 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.
2.3.3. 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 less or non-charged individual or object. An ESD occurs when
an individual with an electrical energy build-up comes into 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 table or bed.
It is highly recommended that the user be given training on ESD-related
warning symbols and preventive procedures.
