Nasal cannula

Nasal cannula is a device used to deliver supplemental oxygen or increased airflow to a patient or person in need of respiratory help. 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.

Overview

The Nasal cannula is made of a flexible tube which is placed under the nose. The tube includes two prongs that go inside the nostrils. Oxygen is delivered through the tube, with the prongs helping to deliver the oxygen directly into the patient's airway.

Uses

The nasal cannula is primarily used to deliver supplemental oxygen to individuals who have low oxygen levels in their blood, a condition known as hypoxemia. It is also used to deliver oxygen to individuals who have difficulty breathing on their own, such as those with chronic obstructive pulmonary disease (COPD) or during and after surgery.

Advantages

The nasal cannula is a simple, easy to use and non-invasive device. It allows the patient to eat, talk and drink while still receiving the necessary oxygen. It is also more comfortable and less claustrophobic than a full face mask.

Disadvantages

Despite its many advantages, the nasal cannula can cause dryness and soreness in the nostrils and can be uncomfortable if the flow rate is too high. It also may not provide enough oxygen for individuals with severe breathing difficulties.
