What is a medical oxygen concentrator?

1. 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 90–95% oxygen from the surrounding air, by engrossing nitrogen. http://www.prettyhome.cn/

2. Medical Oxygen Concentrator • Easy to carry unitsusually produce 4–10 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.

3. 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.

4. 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.

5. 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.

6. 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.
