Changing the frequency of the oxygen cannula – this is a question many people who rely on oxygen therapy ask themselves. It's not just about comfort, but above all about safety and hygiene. Another frequently asked question is: How often does an oxygen cannula need to be changed ? The correct answer depends on several factors, including the device used, the duration of use, and the individual health condition of the patient.

Why is changing the oxygen cannula so important?
Changing the frequency of oxygen tubing is a crucial aspect of caring for patients with chronic respiratory diseases such as COPD. Regularly replacing the tubing minimizes the risk of infection, prevents skin irritation, and ensures a consistent oxygen supply. But how often should an oxygen tube be changed?
Standard cannulas should be changed every 2–4 weeks, according to recommendations. Disposable products should be changed even more frequently. The VARON VH-3 nasal cannula, for example, is suitable for up to seven uses. For people who require long-term oxygen therapy, VARON now also offers accessories that last 4–5 months and can be washed multiple times – meaning greater sustainability and everyday convenience.
The right oxygen supply: An overview of the VARON series

-
Portable series : Compact and powerful – ideal for on the go, even during longer stays away from home.

Flu season and COPD: Why hygiene matters now

Especially during flu season, it's important for COPD patients to protect themselves. Regular face masks can be uncomfortable – particularly for patients with impaired lung function. A convenient alternative: home oxygen therapy with a VARON device.

VARON's portable devices are designed to offer maximum comfort even on the go. This ensures easy breathing – even when the outside world is plagued by viruses.
What you should pay attention to when switching

How often does an oxygen hose need to be replaced? – The answer depends not only on the intensity of use, but also on individual living conditions. In humid environments, for example, the material can age more quickly. Here are some tips:
-
Check the nasal cannula and tubing daily for cracks, discoloration, or unpleasant odors.
-
Make sure that no kinks are created that could impede the flow of oxygen.
-
Clean reusable products regularly and consistently replace disposable products after a maximum of seven uses.
-
Always use accessories that are specifically recommended by the manufacturer – such as VARON – for the respective device.
Changing the frequency of the oxygen cannula is therefore an important part of your health routine and should not be neglected.
