A nasal cannula is a medical device to provide supplemental oxygen therapy to people who have lower oxygen levels. This device consists of a lightweight tube which on one end splits into two prongs which are placed in the nostrils and from which a mixture of air and oxygen flows. There are two types of nasal cannulas: low flow and high flow.
Nasal cannulas are used to deliver oxygen when a low flow, low or medium concentration is required, and the patient is in a stable state. The device has two prongs and sits below the nose. The two prongs deliver oxygen directly into your nostrils.
