10 Best Oxygen Concentrator Of 2023 | Buy Portable Machine

Portable oxygen concentrators are life-saving machines that can help people who need medical oxygen on a regular basis. The oxygen concentrator delivers oxygen to a person in need at significantly higher concentrations than the surrounding air. Air contains approximately 21% Oxygen and 78% Nitrogen. The concentrator removes the Nitrogen and replaces it with air that has a higher concentration of Oxygen – approximately 93%.

When there is low oxygen saturation in blood while the patient is lying in bed, suffering from Dyspnea, Chronic Obstructive Pulmonary Disease, or Hypoxemia, it is used as a substitute for cylinders of compressed oxygen.

Your experience with oxygen therapy could very easily be negatively impacted by a concentrator that is too bulky, too loud or even a machine that lacks the power you require. Once your oxygen requirements have been satisfied by a perfect and portable oxygen concentrator, you can focus on leading an active and healthy lifestyle. For mild cases and post-operative or post-hospital care at home, a maximum of 5 LPM flow concentrator is advised. If the patient requires higher rates of oxygen flow, it is always best to admit the patient to the hospital.

Frequently Asked Questions

1. Will my body become dependent on Oxygen Concentrator on its regular use?

No, Oxygen is not addictive at all. Many patients are apprehensive regarding this, and try to reduce the usage of the Oxygen Concentrator or avoid it totally. The use of an Oxygen Concentrator is prescribed by doctors when the lungs of any patient have become weak, and the 21% oxygen supply of normal air is not enough for the lungs to supply the required amount of oxygen to the blood.

2. What is the difference between Pulse Flow and Continuous Flow?

Oxygen concentrators are of two types: pulse flow concentrators and continuous flow concentrators. Continuous flow is like an oxygen tank or liquid oxygen tank that supplies a constant stream of oxygen that is measured in liters per minute (LPM).

Pulse flow machines are more advanced with the ability to measure your breathing rate. When a person inhales, the pulse dose machine will put out a small dose of oxygen called a “bolus”. Pulse flow concentrators are smaller and lighter than continuous flow oxygen concentrators.

3. Can I use more than the prescribed amount of Oxygen?

No, using more than prescribed oxygen can cause Oxygen toxicity/Oxygen poisoning in the body. This may cause damage to the eyes, alveolar damage, acute respiratory distress syndrome (ARDS), destruction of neurons, etc.

4. What is the maximum concentration of oxygen that can be achieved with the concentrator?

Up to 94%.

5. What kind of maintenance is required for the oxygen concentrator?

Oxygen concentrators are easy to maintain. The coarse filter needs to be washed daily. Also, replace the other filters as instructed by the manufacturer in the user manual that comes with the oxygen concentrator. The filters may also be changed depending on local conditions such as dust, humidity, pollution, etc. Skilled mechanical maintenance is needed only once a year. The bacterial filter which is located before the oxygen outlet of the concentrator must be changed every year, or more frequently, depending on the amount of use of the concentrator. Every concentrator comes with an hour meter to record the working hours for service purposes.

6. What are the Precautions during usage of the oxygen concentrator?

The oxygen concentrator should be placed as far away from the window as possible to avoid dust and moisture, and open flames also. It should not be used to deliver oxygen through the head box or face mask. Always use a cannula. Keep an oxygen cylinder as a backup oxygen supply system in case of prolonged power failure.

7. Can the portable Oxygen Concentrator be used while sleeping?

Yes, Portable Oxygen Concentrators (POC) can be used while sleeping. However, it is recommended to use the Pulse mode, not the Continuous mode. In Pulse mode, POCs will work as long as you breathe through your nose, and that too with sufficient pressure to trigger a breath in the machine. It is recommended to use POC with high sensitivity as during sleep the triggering pressure of each breath drops.

Continuous mode is also recommended for patients who after falling asleep use their mouth for breathing. Therefore, consult your physician before using a particular POC for sleep.
