    Concentrator Supplies FAQs

      How Often Should I Change My Nasal Cannula?

    One of the most critical supplies for someone using portable oxygen or an Oxygen Concentrator is the Nasal Cannula. The Nasal Cannula is the mechanism that delivers oxygen to the nose. Some experts recommend changing it once every 10 days, but it's safe to change it as often as every 2 weeks. The only exception to this rule would be if you get sick. After getting through the illness, the Nasal Cannula should be changed immediately.

    Nasal Cannulas harbor germs and form cracks over time. Due to the cannula's proximity to the nose, germs can hide deep in the cracks in the cannula and cause another infection. This is why it's important to replace the Nasal Cannula immediately should you get sick. Otherwise, it's ok to change your Nasal Cannula once every 10 - 14 days.

      What is Oxygen Therapy?

    Oxygen therapy is a medical treatment for those with COPD and other pulmonary complications that prevent them from being able to breathe in enough Oxygen (O2) on their own.

    Oxygen therapy includes the use of an oxygen tank or concentrator that provides oxygen to the user through a tube and nasal cannula.

      What Types of Concentrators Are Available?

    There are two main types of oxygen concentrators: stationary and portable.

    • Stationary Concentrators
      • Stationary concentrators are larger units meant to be used exclusively at home.
      • Due to their larger size, they are capable of providing continuous oxygen flow, some even as high as 10 LPM (Liters per Minute).
      • When paired with long oxygen tubing, the stationary concentrator can allow the user to move around the home while receiving oxygen, without carrying anything other than the tubing.
    • Portable Concentrators
      • Portable concentrators are smaller units meant to be used both at home and taken along with the user outside of the home.
      • Portable units vary in size, with some being transported on a cart with the user, and others small enough to be carried with a shoulder strap or in a backpack style bag.
      • In order to be smaller in size, portable concentrators have smaller reservoirs, and as a result mainly provide pulse dose therapy. Some portable concentrators do offer continuous flow, but only up to 1-2 LPM.
