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