How to choose a Portable Oxygen Concentrator (POC)

Posted by Shannon Falkson on

There are several factors to take into account when considering purchasing a POC that usually come down to a series of trade-offs between size (weight), battery duration, and clinical oxygen needs and price. 

Size: The best Portable Oxygen Concentrators range in size from the Inogen One G4 weighing 2.8 pounds to the SeQual Eclipse 5 weighing 22 pounds. Considerations on size include whether you want to carry or wear your concentrator (over your shoulder, around your waist, or in a backpack) or roll your concentrator in a cart or attach it to a wheelchair or walker. 

Battery Duration: All POCs include three power sources: a battery, a power cord that plugs into a regular (AC) power outlet and a battery cord that plugs into a DC (car cigarette lighter) power source. Many POC's offer a single or double battery option which offers longer battery life but comes with additional weight. To decide how much battery life you will need, you have to consider how many hours you will need to rely on battery power between access to an AC or DC power source. The smallest unit available, the Inogen G4 with a single battery weighs 2.8 pounds and lasts 2.7 hours at a setting of 2. The Inogen One G3 with a double battery, by contrast, weighs 5.9 pounds and lasts 8.5 hours at a setting of 2. The longest lasting battery comes with the SeQual Eclipse 5, weighing almost 22 pounds, comes with a cart on wheels, and lasts 10 pounds at a pulse dose setting of 2. 

Clinical Oxygen Needs: Portable Oxygen Concentrators have two important clinical differences: their liter flow (settings) range and whether they offer a continuous flow of oxygen, a pulse-dose flow or both. The smallest portable oxygen concentrators have a lower liter flow. The smallest unit available, the Inogen One G4, has a range of 1-3, the slightly larger Inogen One G3 has a range of 1-5  while the SeQual Eclipse 5 has a range of 1-10. Pulse Dose means that the portable oxygen concentrator senses when you are about to take a breath and provides oxygen when you are inhaling and not "wasting" oxygen when you are exhaling. Pulse dose systems work effectively for the majority of patients but some patients require a continuous flow of oxygen.  There are Portable Oxygen Concentrators that offer continuous flow settings for those who need a continuous flow of oxygen while at activity, at rest, while sleeping or all of the above.

Price: The final differentiator with portable oxygen concentrators is price. The range of price is from $2295 - $2900. Factors influencing the price include the battery package selected (many offer a single or double battery option), the included features and the included accessories. For those who are interested, we offer a payment plan to pay over time through PayPal Finance.
