Nasal Cannulas are used for their simplicity and patient compliance in delivering supplementary oxygen. Ambient air is entrained through the nostrils, with the FiO2 achieved being proportional to the flow rate of oxygen (1-6 l/min), the patient’s tidal volume, inspiratory flow rate, and the volume of the nasal pharynx.
The nasal cannula is a device used to deliver supplemental oxygen or airflow to a patient or person in need of respiratory help. This device consists of a PVC plastic tube which fits behind the ears, and a set of two prongs which are placed in the nostrils.
