Heated High Flow Nasal Cannula and Bilevel Positive Airway Pressure in Pediatric Asthma Exacerbations.

Objective: Heated High Flow Nasal Cannula (HHFNC) and Bilevel Positive Airway Pressure (BPAP) are non-invasive respiratory support modalities used in pediatric asthma exacerbations. We aim to examine differences in characteristics and outcomes for patients admitted to the Pediatric Intensive Care Unit (PICU) on standard therapy (ST) alone (continuous albuterol and systemic corticosteroids), ST plus HHFNC, and ST plus BPAP.

Methods: This is a retrospective and prospective observational cohort study.
