Best Portable Oxygen Tanks for Seniors

Seniors suffering from cardiopulmonary challenges that prevent the lungs from absorbing enough oxygen can find it hard to source enough oxygen on their own. As such, they need supplemental forms of oxygen to help them breathe. Having home oxygen devices with them at all times is not optional. When they need to move around traveling, walking or going to appointments, they have to go with portable oxygen tanks.

As we grow older, lung function naturally declines. According to the American Medical Association, 30+ million Americans suffer from some form of chronic lung disease, and 3 percent of those people need some form of oxygen therapy. Recent advances in technology have allowed for more portability. This allows patients to carry out their day-to-day activities while still getting the required amount of oxygen.

Why is Portability Important?

Seniors who need supplemental oxygen opt for portable oxygen concentrators (POCs) over traditional oxygen tanks to maintain an independent lifestyle. Conventional oxygen tanks are mostly used in hospitals and homes and can weigh up to 150 pounds. Due to their weight, they allow minimum freedom of movement.

The bulky oxygen canisters also need to be regularly re-filled with compressed oxygen or liquid, putting patients’ health at risk. Portable oxygen concentrators, on the other hand, weigh much less and make traveling easy. Instead of going to a hospital to get oxygen from stationary units, a POC can comfortably fit in a shoulder bag and is guaranteed to never run out of oxygen.

Understanding Portable Oxygen Concentrators

Portable Oxygen Concentrators are medical grade breathing devices meant for people with chronic obstructive pulmonary disease (COPD), sleep apnea, cystic fibrosis, congestive heart failure, asthma and other breathing-related conditions necessitating oxygen therapy. POCs don’t require the big tanks or routine refills, making them compact, lighter and easier to travel with.

POCs work using the following 4-step process:

  1. These therapeutic grade units source oxygen from ambient air and send the air through small compressors inside the system.
  2. Next, the air is pressurized and filtered through bed sieves to get rid of nitrogen.
  3. The oxygen is then compressed and flows to the user through a mask or nasal cannula (nasal tube).
  4. The remaining concentrated oxygen returns to the chemical filters, getting rid of the accumulated nitrogen to prepare the system for the next cycle.

The process consistently produces purified oxygen (87-96 percent purity levels), the same quality as traditional oxygen canisters. These electrically operated devices are powered by batteries. The battery life per charge depends on the model of the system and the flow rate. But as long as they have a power source, they can run 24 hours a day. Compared to earlier models, POCs are very quiet.

POCs: Continuous or Intermittent Flow?

Treatment may be needed chronically, while some seniors only use POCs occasionally during the day. Oxygen is delivered to the patient by Pulse/Intermittent Dose or Continuous Flow. Continuous flow means the concentrator delivers oxygen at a constant level in liters per minute while in Pulse Dose, it is delivered when the patient initiates a breath. Seniors are advised to use Continuous Flow when sleeping.
