Non-invasive mechanical ventilation in hypoxemic respiratory failure: Just a matter of the interface?

Noninvasive mechanical ventilation in early acute respiratory distress syndrome

“…The results of the trial strongly encourage to consider the use of HFNC in patients with AHRF as the first -line rebreathing and improve the patient-ventilator interaction. 56,57 The helmet appears to be a very promising interface for delivering NIV in patients with ARDS. It can be used to deliver both continuous free -flow CPAP or pressure support.…”

“…It effectively replaces the invasive tube and the surgical procedure of invasive PPVs providing equivalent results thus gaining momentum in wide usage from critical care units (CCU) to homes evolving in different forms according to their place and phase of usage [Borel et al 2019 ; Díaz Lobato and Mayoralas Alises 2013 ; Scala and Pisani 2018 ). It has been highly utilized in acute phases of respiratory disorders, primarily to treat chronic obstructive pulmonary disorder (COPD) (Duiverman 2018 ), hypoxaemia (Moerer and Harnisch 2016 ), acute respiratory failure (ARF) (Brochard et al 2002 ), sleep apnoea (Nicolini et al 2014 ), pulmonary oedema (Bello et al 2018 ), and also reducing the risk of ventilator-associated pneumonia (VAP) (Hess 2005 ) associated with the invasive ventilation. With respect to the COVID-19 pandemic, the US Food and Drug Administration presented a suggested list of supportive device to fight against the coronavirus infection, wherein the NIVs were asked to be used with incorporation of proper filtration for reducing the chance of disease transmission (USFDA 2020 ) which also increases the use of NIVs.…”
