  • Inogen One G3 Compared to the AirSep Freestyle 3

    Oxygen concentrators offer a light-weight portable alternative to traditional, bulky, oxygen tanks. Because they pull oxygen from the surrounding air, you don’t have to worry about tanks being delivered or being refilled. Instead, room air passes into the unit, which separates oxygen from the nitrogen in the air, and delivers a high flow of oxygen right to the patient. This type of oxygen unit allows the user freedom of movement and a much more active lifestyle than a traditional tank. Today, let’s take a look at and compare two portable oxygen concentrators: the AirSep Freestyle 3 and the Inogen One G3. Both allow for maximum freedom with slight variations in specifications.

  • Maintaining a Healthy Diet for COPD Patients

    If you have COPD (Chronic Obstructive Pulmonary Disease), you know how difficult everyday tasks can be. Having trouble breathing can be exhausting, and not having enough oxygen in your body leads to fatigue. While you still need to take the medication your doctor prescribes you; you can look into other health and diet tips for COPD patients.
