Effects of an asymmetrical high flow nasal cannula interface in hypoxemic patients.

ABSTRACT:

Background

Optimal noninvasive respiratory support for patients with hypoxemic respiratory failure should minimize work of breathing without increasing the transpulmonary pressure. Recently, an asymmetrical high flow nasal cannula (HFNC) interface (Duet, Fisher & Paykel Healthcare Ltd), in which the caliber of each nasal prong is different, was approved for clinical use. This system might reduce work of breathing by lowering minute ventilation and improving respiratory mechanics.

Methods

We enrolled 10 patients ≥ 18 years of age who were admitted to the Ospedale Maggiore Policlinico ICU in Milan, Italy, and had a PaO₂/FiO₂ < 300 mmHg during HFNC support with a conventional cannula. We investigated whether the asymmetrical interface, compared to a conven
