The document lists and briefly describes several common electrical devices found in hospitals, including X-ray machines, MRI machines, heart-lung machines, defibrillators, nebulizers, cardiac monitors, ultrasound machines, diathermy machines, electrical beds, and surgical lights. X-ray machines and MRI machines produce images of internal structures, while heart-lung machines, defibrillators, and nebulizers assist with heart and lung functions. Cardiac monitors, ultrasound machines, and diathermy machines are used for various diagnostic and surgical purposes. Electrical beds and surgical lights provide positioning and illumination for procedures.

• DEFIBRILLATOR
• NEBULIZER
• CARDIAC MONITORS
• ULTRASOUND MACHINE
• DIATHERMY MACHINE
• ELECTRICAL BEDS
• SURGICAL LIGHTS

3. X-RAY MACHINE
 An X-ray machine is a device that produces X-Rays.
 X-rays are highly penetrating, ionizing radiation
 X-ray machines are used in health care for
visualising bone structures, during surgeries
(especially orthopedic) to assist surgeons in
reattaching broken bones with screws or structural
plates, assisting cardiologists in locating blocked
arteries and guiding stent placements or performing
angioplasties and for other dense tissues such as
tumours.

4. MRI MACHINE
 Magnetic resonance imaging (MRI) is a technique
that uses a magnetic field and radio waves to
create detailed images of the organs and tissues
within your body.
 Most MRI machines are large, tube-shaped
magnets. When you lie inside an MRI machine, the
magnetic field temporarily realigns hydrogen
atoms in your body. Radio waves cause these
aligned atoms to produce very faint signals, which
are used to create cross-sectional MRI images —
like slices in a loaf of bread.

5. HEART-LUNG MACHINE
 The heart–lung machine is a system which takes
over the function of the heart and the lungs with
sufficient safety to maintain life while the heart is
stopped or opened to allow surgery on the coronary
arteries or the heart valves, or to allow repair of
congenital abnormalities.

6. DEFIBRILLATOR
 The defibrillator is used in défibrillateur
cardiaque which means when a person have
heart attack it is used to give electronic shock to
the heart so that the heart starts working and
can start pumping blood to brain and other
organ of the body. Defibrillation is a procedure
used to treat life threatening conditions that
affect the rhythm of the heart such as cardiac
arrhythmia, ventricular fibrillation and pulse
less ventricular tachycardia.

7. NEBULIZER
 A nebulizer turns liquid medicine into a mist to help
treat your asthma. They come in electric or battery-
run versions. They come in both a portable size you
can carry with you and a larger size that’s meant to sit
on a table and plug into a wall. Both are made up of a
base that holds an air compressor, a small container
for liquid medicine, and a tube that connects the air
compressor to the medicine container. Above the
medicine container is a mouthpiece or mask you use
to inhale the mist.

8. DIATHERMY MACHINE
 Commonly known as Monopolar
Bipolar Diathermy machine. Used
in Electrosurgery.
 This device produce high-
frequency electrical current to
cut, coagulate, dessicate &
fulgurate tissue.
 Helps in preventing blood loss
during surgery.

9. ULTRASOUND MACHINE
 An Ultrasound machine makes images so that
organs inside the body can be examined.
 The machine sends out high frequency sound
waves which reflect off body structures.The
computer receives the waves and uses them to
create a picture.
 Unlike an X-ray or Ct scan,it does not use
ionizing radiation.

10. CARDIAC MONITOR
It is an electrical device generally used
for heart rate monitoring , most
commonly used in emergency rooms and
critical care areas.
Cardiac monitor displays heart rate ,
body temperature , ECG, oxygen
saturation , blood preasure

11. SURGICAL LIGHTS
 A surgical light – also referred to as an
operating light or surgical lighthead – is a
medical device intended to assist
medical personnel during a surgical
procedure by illuminating a local area or
cavity of the patient.
 A combination of several surgical lights is
often referred to as a “surgical light
system”.

12. ELECTRICAL BEDS
 A Full Electric Hospital Bed is a large,
specially designed hospital bed built
on a sturdy, metal, and motorized
adjustable-height bed frame that
allows the head, knee and foot
segments to be adjusted, as well as
enabling the entire bed to be lowered
or raised by the touch of an easy-to-
use handheld electronic control,
which results in an anatomically
correct sleep surface for each unique
user.
