How to choose oxygen concentrator ?

Emerdepot provides oxygen concentrator solutions for both portable and stationary use. If you or a loved one need oxygen therapy in your daily life, then there’s no doubt you’re at least somewhat familiar oxygen concentrator machines. These devices were created with the specific purpose of gathering oxygen and nitrogen from ambient air, quickly filtering it, and then giving the patient safe, oxygen-enriched air for better breathing.

How oxygen concentrator machine works?

The machine first takes ambient air through a compressor, which is primarily composed of nitrogen and oxygen. The air is then sent through a number of filtering devices to separate the nitrogen and clean the oxygen. After passing through a pressure regulator to regulate airflow, the purified oxygen is then supplied to the patient using oxygen tubing, a mask, or a nasal cannula.

Frequently Asked Questions

Q: Do you need a prescription to buy an oxygen concentrator?

A: Yes, Oxygen concentrators are medical-grade oxygen therapy devices, and as such, they cannot be purchased or obtained without a current prescription.

Q: Can you sleep while using an oxygen concentrator?

A: Yes. To find the appropriate flow rate for you, your doctor will most likely want to perform a sleep study before you may use your oxygen concentrator while sleeping. Then, you should pick a concentrator that is quiet enough for you to sleep soundly while it is running.

Q: How long do most oxygen concentrators last?

A: Depending on the model, the lifespan of portable oxygen concentrators ranges from 4 to 7 years, while that of normal oxygen concentrators is closer to 6 to 10 years.

Ultimately, it is advised to replace the oxygen concentrator whenever its oxygen concentration product starts to fall below 80%. (as opposed to the usual range of 87 to 99 percent). At that point, it is required to either buy new filters or an entirely new product.

Q: What are some of the side effects of using an oxygen concentrator?

A: As is the case with the majority of oxygen therapy devices, skin irritation and nasal dryness are the most frequent side effects. When using oxygen for a prolonged period of time or at high flow rates, this happens as a result of the constant airflow entering the sinuses.
