Material Safety

All of the materials used to make these cannulas are the same that all manufacturers use (PVC). The super flexible tubing is a medical grade PVC compound that passed standard toxicology tests. The adhesive used to bond all connections is the same used by major manufacturers. Like all cannulas these are not sterile but they are made in a clean environment and all the tubing and fittings are manufactured to the same standards of cleanliness.

How Long Do They Last

It varies among patients.  The Oxy-Breather single sided cannula can last anywhere from a few weeks to several months depending on use and environmental conditions.  Oxygen patients should consult their physicians regarding best practices for cannula replacement.
