Noninvasive approach for de novo acute hypoxemic respiratory failure: noninvasive ventilation, high-flow nasal cannula, both or none?
To summarize the recent evidence regarding the use of noninvasive strategies for de novo acute hypoxemic respiratory failure (AHRF). ⋯ In the last two decades, the use of NIV and HFNC in patients with AHRF has considerably expanded, changing the paradigm of management of AHRF. Choice of each technique should be based according to centre experience and patient tolerability. However, when using noninvasive strategies for AHRF, it is crucial to predefine specific criteria for intubation and monitor patients closely for early detection of clinical deterioration to avoid delayed intubation.

In patients with acute respiratory distress syndrome (ARDS), airway pressure release ventilation (APRV) has been purported to have several physiological benefits. This review synthesizes recent research evaluating APRV mode and provides perspectives on the utility of this mode in children with ARDS. ⋯ There have been significant recent advancements in our understanding of the clinical utility of APRV in children with ARDS. The recent trial highlights the urgent need to evolve a consensus on definition of APRV and identify strategies that work. Pending further research, clinicians should avoid the use of a zero-PLOW Personalized-APRV strategy as a primary ventilation modality in children with moderate-severe ARDS.
