What is a Nasal Cannula?
A nasal cannula is a lightweight, flexible medical device used to deliver oxygen to patients requiring respiratory support. It consists of a tube that splits into two prongs, which are inserted into the nostrils, allowing a continuous flow of oxygen. The tubing is connected to an oxygen source, such as a concentrator or tank. Nasal cannulas are commonly used in hospitals, clinics, and home settings for patients with conditions like COPD, pneumonia, or sleep apnea. They are comfortable, allowing patients to eat, talk, and move freely while receiving oxygen therapy.
Nasal Cannula Flow Rate
The nasal cannula flow rate varies depending on the patient’s oxygen needs. Typically, it ranges from 1 to 6 liters per minute (LPM) for standard oxygen therapy. High-flow nasal cannulas can deliver up to 60 LPM, providing better humidification and oxygenation. The correct flow rate is determined by healthcare providers based on the patient's condition and oxygen saturation levels.
