Asthma is a chronic inflammatory disease that affects the airways in the lungs and makes it difficult to breathe. It is one of the most common and costly diseases in the U.S., with an estimated 23 million adults and an estimated 5 million children suffering from asthma. Globally, asthma affected an estimated 262 million people in 2019 and caused 455,000 deaths. Asthma is associated with severe exacerbations that are difficult to treat and often require hospitalization. Approximately one million asthma patients visit emergency departments annually, of which approximately 11% are hospitalized with an average length-of-stay of two to three days. Approximately 50% of asthma patients who visit emergency departments meet treatment failure criteria within four weeks of an exacerbation. Approximately 20% of such patients require a re-visit to the emergency department and an additional approximately 30% require medical care from another source, such as urgent care or medical clinics. Current standard of care treatment for these patients includes fast-acting inhaled bronchodilators and oral or intravenous (“IV”) corticosteroids. Severe cases may require IV magnesium sulfate, heliox therapy, and noninvasive ventilation.
