Use Cases of non-prescription POCs

Here are some practical uses of non-prescription portable oxygen concentrators.

High-altitude activities

While at higher elevations, you may experience an increased breathing rate and hyperventilation, which can cause altitude sickness. Using a non-prescription portable oxygen concentrator can prevent the condition while hiking or climbing in high-altitude areas.

Mental workers

Concentration and focus of a patient are key elements when dealing with mental issues. Mental health workers can use controlled supplemental oxygen to enhance a patient's focus and alleviate their fatigue.

Post-exercise recovery

A non-prescription, portable oxygen concentrator can help you recover quickly after exercise if you experience shortness of breath afterward. However, it is essential to consult your doctor for a proper diagnosis and treatment.

Pregnant women

A continuous flow POC can be essential for pregnant women who experience breathing difficulties during sleep. It will help the user sleep comfortably while getting enough oxygen.

Emergency backup

Emergency responders require oxygen equipment during their operations. Supplemental oxygen can go a long way in rescuing lives, especially if the victim has a condition or injury that restricts breathing. The best non-prescription portable oxygen concentrator for emergency backup is OxyGo.

Precautions

We must state that, if you are considering purchasing an oxygen concentrator, take note of the following precautions.

Not a medical replacement

If you have a respiratory condition that makes your breathing difficult, a non-prescription portable oxygen concentrator can improve your oxygen intake. However, continue taking any other medications as prescribed by your healthcare provider.

Consult a doctor before use

Before using any medical equipment, it is essential to consult your doctor. In a clinic, doctors will diagnose your condition and provide the correct treatment recommendations, as well as guide you on the appropriate equipment and settings.

Avoid uncertified devices

Some organizations provide certifications to medical equipment manufacturers, verifying that the product is safe for medical use. You need to confirm that your POC of choice is certified. You can ask your supplier for proof or verify it against the certifying body's database.

Conclusion

Non-prescription portable oxygen concentrators are ideal for emergency response. They can also support individuals who experience breathing difficulties due to environmental factors, such as high altitude.

However, before using supplemental oxygen, you need to consult with your doctor. When using the device, ensure that you use the correct settings to avoid oxygen poisoning.
