What is a medical oxygen concentrator?

• Oxygen concentrators (often called oxygen
  generators) are largely used as a substitute to
  compressed oxygen gas cylinders. They make nearly
  9095 oxygen from the surrounding air, by
  engrossing nitrogen.

Medical Oxygen Concentrator

• Easy to carry unitsusually produce 410 l/min,
  and bigger devices, can prepare up to 25 l/min
  and supply several anaesthetic machines can also
  be obtained. All of these devices are
  electrically operated, so a power failure will
  lead to the collapse of oxygen supply lest a
  reserve generator, or a battery backup and power
  inverter start working. Alternatively, a cylinder
  of oxygen can be retained for emergency use.

low-end oxygen concentrator machine

• As the pressure of gas from a low-end oxygen
  concentrator machine is comparatively low, the
  emergency oxygen switch on an anaesthetic machine
  will not operate perfectly, but turning up the
  flow meter can quickly throw out anaesthetic
  vapour from a breathing installation. The low
  flow and lower pressure of gas provided from
  these units restricts their use with some
  ventilators, and with bigger animals. However,
  the small, comparatively portable units are
  perfect for use in small operationtheatres, where
  transport and storage of oxygen cylinders can be
  an issue. Advancedmachines are considerablysilent
  than outdates models, and additional disturbance
  is not an issue if a larger unit is located away
  from the nearby theatre region. The buying cost
  of this equipment has reduced significantly in
  recent times, and they can now be taken as an
  economical and easyalternate to compressed gas
  cylinders.

Better oxygen availability

• Better oxygen availability, free from the use of
  pressurized gas and electrical power production,
  can be done by connectinga medical oxygen
  concentrator to a draw-over anaesthetic apparatus
  as initially defined by Fenton.65 Maintenance
  needs are less, and servicing is suggested only
  after nearly 10,000 hours of application. The
  advantages are aplenty, but a constant
  electricity supply is important.

oxygen concentrator machine works

• The oxygen concentrator machine works by
  employing a compressor to throw ambient air
  alternately through one of two canisters with a
  molecular sieve of zeolite granules that
  reversibly engrosses nitrogen from compressed
  air. The controls are easy and made up of an
  on/off switch for the compressor and a
  flow-control switch to deliver 0 to 5 L/min.

The oxygen flow of the medical oxygen

• The oxygen flow of the medical oxygen
  concentrator counts on the size of the unit, the
  input of oxygen, the minute volume, and pattern
  of ventilation. The addition of dead space (or
  oxygen economizer tube) at the outlet improves
  the performance, and predictable concentrations
  of more than 90 oxygen can be obtained with
  flows between 1 and 5 L/min irrespective of the
  ventilation pattern. Much lower concentrations
  and reduced predictability was observed when the
  dead space tubing was eliminated.
• The possible dangers of oxygen concentrators are
  not too may, given that they are placed in the
  operating room so that the in-draw area is free
  from pollutants.
