In todays lifestyle oxygen concentrator is quite helpful for healthy living. In this slide know every things about Portable Oxygen Concentrator eg. how does it works, history of oxygen concentrator, developement and why we should use it.

2. What is a Portable Oxygen Concentrator?What is a Portable Oxygen Concentrator?
• A portable oxygen concentrator,
(POC) is a portable device used
to provide oxygen therapy to a
patient at substantially higher
concentrations than the levels of
ambient air. It is very similar to a
home oxygen concentrator, but
it smaller in size and more
mobile.

3. • The portable oxygen concentrator enables
patients to be more independent. The POC range
that Intermedical cover are small & lightweight;
run on battery power; can be powered in a car and
are FAA (Airline) approved.

4. The History of Oxygen ConcentratorThe History of Oxygen Concentrator
• Portable oxygen concentrators have been around for
decades; but the older versions were bulky, not reliable,
and were not permitted on airplanes.
• Since 2000, a number of manufactures have improved their
reliability and they now produce anywhere between 1 and 6
liters per minute (LPM) of oxygen.

5. • There are versions that provide pulse or continuous flow.
The portable concentrators plug directly into a regular
house outlet for charging at home or hotel; but they came
with a power adapter that can usually be plugged into a
vehicle DC adapter.
• They have the ability to operate from the battery power as
well for either ambulatory use, or away from a power
source, or on an airplane.

10. How does it work?How does it work?

11. • The technology behind a Portable Oxygen Concentrator
is based on the same principle as a home domestic
concentrator.
• Air at barometric pressure contains 21% Oxygen
combined with Nitrogen and a mixture of other gases. A
miniaturised compressor inside the machine will
pressurise this air through a system of chemical filters
known as a molecular sieve.

12. • This chemical filter is made up of silicate granules
called Zeolite. The Zeolite will sieve the nitrogen out
of the "air" concentrating the Oxygen.
• Part of the produced Oxygen is delivered to the
patient; part is fed back into the sieves to clear the
system from the accumulated nitrogen, making it
ready for the next cycle. Through this process, this
system is capable of producing medical grade
oxygen of up to 96% consistently.f up to 96%
consistently.

13. • The latest models can be powered from mains
electricity supply, 12v DC (Car/Boat etc..) & battery
packs making the patient free from relying on using
cylinders & other current solutions that put a
restriction on time, weight & size.
• Most of the portable oxygen concentrator systems
available today provide oxygen on a pulse (on-
demand) delivery in order to maximise the purity of
the oxygen.

14. The Difference Between The Difference Between
On­Demand& Continuous FlowOn­Demand& Continuous Flow
• Most portable oxygen concentrators are built from the size of a
binocular case and weigh less than a couple of bags of sugar.
The reason for this is because of the on-demand system. It
allows the concentrator to be built with smaller components
than that of a domestic concentrator.
• Because the patient only inhales oxygen when they breathe in,
when exhaling oxygen is wasted. Therefore what manufacturers
decided to do is build a machine that works on your breathing...
only providing oxygen when necessary, keeping wasted oxygen
to a minimum.

15. • Most on-demand portable oxygen
concentrators work on settings which
are very much equivalent to a specific
LPM (Litre per minute). To determine
this, the machine works on a bolus
system. The bolus size is measured in
millilitres and is the "shot" of oxygen
released upon inhalation.
• The size of the bolus on each setting is
worked out based on the amount of
oxygen inhaled if the patient was on
continuous flow oxygen. Since oxygen
isn't required when we exhale, oxygen is
normally wasted; hence the reason
behind the this type of technology.

16. • Technology has progressed in a
way so that boluses can be made
variable based on the patients
breathing rate. This is particularly
useful for using an on-demand
machine whilst sleeping. Naturally
the breathing rate slows whilst
sleeping. A machine with a
variable bolus detects a slower
breathing rate; adjusting the bolus
size so that its a longer shot of
oxygen upon inhalation, but still
maintaining the patients
prescription of x amount of litres
per minute.

17. • It is not usually recommended that
an on-demand device be used during
sleep, however clinical studies have
found that some on-demand portable
oxygen concentrators are just as
affective as a continuous flow
oxygen concentrator. On-demand
devices are not suitable for sleep for
patients with the sleeping disorder
sleep apnoea.
