How Can a POC for Oxygen Therapy Work with you Lifestyle

Portable oxygen solutions are a good choice for patients requiring oxygen therapy, but who still want to be able to live active, healthy lives.[1] While different types of oxygen therapy are often necessary for anyone living with a lung condition, a portable oxygen concentrator for breathing may help you fit the therapy more easily into your life. Stationary oxygen concentrators require you to stay in one place for supplemental oxygen, while portable oxygen solutions using tanks, liquid systems and home transfill systems require refills and canisters or cylinders, some weighing 40lbs or more.[1] None of these options are ideal for someone wanting to travel without worry.

A POC, on the other hand, is the portable oxygen solution made for people who want to retain their mobility and active lifestyles.[1]  Because POC oxygen is pulled directly from the atmosphere, it never runs out, making it ideal for use when you’re at home or on the go, as long as you have access to a battery or other power source.  A POC runs on rechargeable battery or any AC or DC power source, so it can be used while traveling, and then recharged easily. It is also lightweight and easy to carry, which may make it preferred  to other portable oxygen solutions.[1]
