NASAL CANNULA FOR OXYGEN DELIVERY.

nasal cannula

Tubing used to deliver oxygen at levels from 1 to 6 L/min. The nasal prongs of the cannula extend approx. 1 cm into each naris and are connected to a common tube, which is then connected to the oxygen source. It is used to treat conditions in which a slightly enriched oxygen content is needed, such as emphysema. The exact percentage of oxygen delivered to the patient varies with respiratory rate and other factors.

(6-8) NIV includes various types of ventilation such as nasal intermittent positive pressure ventilation (NIPPV), NCPAP provided through soft nasal prongs or masks, and humidified oxygen delivered by high flow nasal cannula.
After position, operation was started, perioperative Haemodynamic, respiratory, EtCO2, , SpO2 monitoring done periodically with interval of 15 mins and surgeons were told to inform 15 min before the craniotomy was expected to over, all inhalational agents were stopped in both groups, i-gel was removed and nasal prongs applied for oxygenation.
The nasal prongs that deliver it are irritating, but what really bothers him about them is that he won't attend any activities in his assisted living facility wearing nasal prongs and trailing a tank.
Traditionally, high-flow nasal oxygen therapy (up to 15L/min) has been achieved via regular nasal prongs. However, the main limitations of this technique are inability to humidify and heat gases, carbon dioxide accumulation resulting in excessive hypercapnia, oxygen atelectasis, patient discomfort, and mucosal desiccation.
