  • What’s the Difference Between an Oxygen Concentrator and an Oxygen Tank?

    When people think of portable oxygen, a traditional large oxygen tank often comes to mind. These are generally made of steel or aluminum. The oxygen inside comes in the form of pressurized compressed gas, which needs to be handled with care and kept upright. The size of the tank gets larger as the flow rate that a patient requires increases. These tanks are usually quite heavy. They have to be changed frequently, and are available in a smaller size for portability. The pressure valves attached to the tanks must be checked consistently. Gas oxygen is delivered at 100% concentration.

  • Oxygen Concentrators and Sleep Apnea/COPD

    Sleep apnea is a disorder in which you stop and restart breathing repeatedly while sleeping. It can be dangerous if not treated. Symptoms include snoring and feeling sleepy while awake. You may also suffer from headaches, sore throat, and dryness of the mouth. Sleep apnea occurs when muscles located in the back of your throat relax causing a narrowing of the airway, which in turn results in breathing cessation. Although you often don’t remember it, this causes awakening so that breathing will return. Sleep apnea can be caused by being overweight, having a thick neck or narrowed airway, smoking, and alcohol and drug use. Sleep apnea is most common in older men, although it can affect women and people of any age.
