What is a Portable Oxygen Concentrator?

A portable oxygen concentrator (POC) provides oxygen therapy for patients who are on the go. Portable oxygen concentrators are lighter and more compact than home units. They run on batteries so that patients can continue their oxygen therapy no matter where they travel. Having a more mobile device is very important to some patients who live a very active lifestyle. Many people do not want to be held back from their normal lives, so having a POC is the perfect solution. Additionally, some patients may even rely on their portable oxygen concentrators for oxygen therapy at home. 

What is the Average Lifespan of a POC?

Most portable oxygen concentrators last between 4 to 7 years. The lifespan of a POC also depends on how well the patient takes care of their portable unit. It’s important to regularly clean and maintains a device. This will help improve how long the machine lasts. Portable oxygen concentrators can also receive a lot of bumps and bangs as they travel with patients, which can also reduce longevity. To prolong your POC, make sure you are packing it tactfully and carefully when you travel so it can still perform at its best.

How Long Does a Battery Last in A POC?

Batteries provide the essential power for portable oxygen concentrators. It’s important to choose a portable oxygen concentrator with a battery that lasts for the length of time you typically spend away from a power source. Battery durations can range from 3 to 11 hours depending on the model. Portable oxygen concentrators have internal batteries, but the duration can be extended with external backup batteries.

How to Maintain Your POC to Make it Last Longer 

Proper maintenance can help your portable oxygen concentrator last longer. This means taking good care of the outside of the machine. Cleaning the exterior regularly helps prevent dust and grime from being drawn into the air vents, which can reduce performance and lifespan. Also, avoid damage to the device when travelling by packing it tightly and securely in your travel bag.

On a quarterly basis run the battery all the way down and then recharge fully before next use – this helps extend battery life.

When Should POC Service Be Done?

Many issues with portable oxygen concentrators can be resolved without a service technician. Check filters, tubing and cannula for damage if you are experiencing poor oxygen flow. If the problem persists, or you experience other issues you can always contact a service technician to inspect your machine. However, in some instances, purchasing a new oxygen concentrator may be less expensive than repairing one.

Can a POC Be Used All the Time?

Portable oxygen concentrators, like most machines need a cooling period to prevent overheating and damage. Set time aside when you do not use your portable oxygen concentrator. Unplug and disconnect batteries. Keep your POC in a cool place. Avoid heat sources like fireplaces or space heaters and never leave your POC in a hot car.
