Purpose Of Review:
The use of noninvasive positive pressure ventilation (NPPV) is often employed for the management of acute respiratory failure as an alternative to endotracheal intubation and mechanical ventilation. However, evidence to support the application of NPPV use in patients with acute severe asthma is less known.
Recent Findings:
A paucity of evidence is available to support the use of NPPV as part of clinical care in patients with acute severe asthma. A number of small studies in adult and paediatric populations suggest that NPPV may have a beneficial role through improving respiratory rate and reducing the need for more invasive alternatives. Overall NPPV use appeared to be well tolerated with few reports of adverse events.
Summary:
Available evidence is limited by a small number of published trials and lack of methodological rigour in existing study design. There is a need for well conducted clinical studies to establish accurate treatment efficacy, safety and cost-effectiveness, in both the adult and paediatric setting.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Ventilatory Modes
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...
