What is nasal catheter?

A nasal catheter is a medical device used to deliver oxygen or other gases directly into the nasal passages. It consists of a thin tube that is inserted into the nostrils, allowing for comfortable and continuous flow of air or medication. Nasal catheters are commonly used in patients who require supplemental oxygen, such as those with respiratory conditions. They are preferred for their ease of use and non-invasive nature compared to other forms of oxygen delivery.
