Oxygen Concentrator

An oxygen concentrator is a medical device that provides supplemental oxygen by using atmospheric air, which typically contains about 20% oxygen. It filters this air to deliver oxygen that is 90%-95% pure. Doctors may prescribe an oxygen concentrator if you have a condition that lowers your oxygen levels, such as, asthma, lung cancer, COPD, flu, COVID-19, sleep apnea, heart failure, cystic fibrosis, and bronchitis

There are two main types of oxygen concentrators:

​

1. Stationary Oxygen Concentrator: Designed for home use, these weigh about 22 pounds and are equipped with handles or wheels for mobility. They run on electricity, providing constant oxygen (up to 15 liters per minute). Some models include a battery backup for power outages.

​​

2. Portable Oxygen Concentrator: Smaller and lighter, portable concentrators are ideal for running errands or traveling. They usually weigh between 1 and 10 kg and operate on rechargeable batteries. These devices provide oxygen in bursts (pulse dose) and can supply 0.5 - 10 liters per minute, depending on the model

How an Oxygen Concentrator Works?

An oxygen concentrator differs from an oxygen tank, which stores liquid or compressed gas. It draws in room air through a filter and compressor, separating nitrogen from oxygen. The purified oxygen is then delivered to the user via a nasal cannula or mask. There are two types of delivery methods:

  • Continuous Flow: Delivers a constant stream of oxygen.

  • Pulse Dose: Delivers oxygen in bursts during inhalation.

Using an oxygen concentrator requires caution due to the risk of fire. Keep the device at least 10 feet away from, cigarettes, grills, ovens, gasoline, oil, flammable materials and electrical equipment (hair dryers, space heaters, electric blankets, vape pens). Keep the device in an open space to prevent overheating and avoid blocking any vents. Check the instruction manual if the device beeps or sounds an alarm. Most importantly, only use an FDA-approved oxygen concentrator prescribed by a doctor. The usage duration depends on the specific health condition. Most users need supplemental oxygen for 15-24 hours daily. Portable concentrators can last 2-6 hours on a single battery or 5-13 hours on a double battery. Plug-in models run as long as there is power.
