Chapter 21: Patient Safety
Warning
Do not touch the patient, bed or instrument during defibrillation.
Follow the instructions below to ensure a completely safe electrical installation.
The environment where the Portable Patient Monitor will be used should be reasonably free from
vibration, dust, corrosive or explosive gases, extremes of temperature, humidity and so on.
The Patient Monitor operates within specifications at ambient temperatures between 0ºC and
40ºC. Ambient temperatures that exceed these limits could affect the accuracy of the monitor and
cause damage to the modules and circuits.
Grounding the patient monitor
To protect the patient and hospital personnel, the case of patient monitor must be grounded. The
patient monitor is equipped with a detachable 3-wire cable which grounds the instrument to the
power line ground (protective earth) when plugged into an appropriate 3-wire receptacle .If a 3-
wire receptacle is not available, consult the hospital electricians. If there is any doubt regarding
the completeness of the protective grounding wire, the equipment must be operated with internal
battery or DC input.
Equipotential Grounding
Protection class I instruments are already included in the protective grounding (protective earth)
system of the room by way of grounding contacts in the power plug. For internal examinations
on the heart or the brain, the portable Patient Monitor must have a separate connection to the
equipotential grounding system. One end of the equipotential grounding cable (potential
equalization conductor) is connected to the equipotential grounding terminal on the rear panel of
the monitor and the other end to one point of the equipotential grounding system.
The equipotential grounding system is for the safety function of the protective grounding
conductor if ever there is a break in the protective grounding system. Examinations in or on the
heart (or brain) should only be carried out in medically used rooms incorporating an
equipotential grounding system. Check each time before use that the instrument is in perfect
working order.
Warning
Possible explosion hazard if the monitor is used in the presence of flammable anaesthetic.
