High-flow nasal oxygenation for anesthetic management.

High-flow nasal oxygenation for anesthetic management. Korean J Anesthesiol. 2019 Jun 05;: Authors: Asai T, Kim HJ Abstract High-flow nasal oxygenation (HFNO) is a promising new technique for anesthesiologists. The introduction of HFNO during induction of anesthesia and during upper airway surgery has been initiated and its applications have been rapidly growing. The advantages include its easy setting, high tolerability, its ability to produce positive airway pressure, a high fraction of inspired oxygen (FiO2) and some clearance of carbon dioxide. HFNO via nasal cannula can provide oxygen, both in patients breathing spontaneously and in those being apnea, and does not interfere with bag-mask ventilation, attempts at laryngoscopy for tracheal intubation and surgical procedures to the airway. In this review, we describe techniques of the HFNO, and advantages and disadvantages of HFNO, based on the current state of knowledge. PMID: 31163107 [PubMed - as supplied by publisher]
