Acute severe asthma, also known as status asthmaticus, is an acute exacerbation of asthma that does not respond to standard treatments of bronchodilators (inhalers) and corticosteroids. [2] Asthma is caused by multiple genes , some having protective effect, with each gene having its own tendency to be influenced by the environment although a ...
Paroxysmal nocturnal dyspnea is a serious medical symptom that can develop into worsening conditions. Many tests can be done in order to evaluate the cause of paroxysmal nocturnal dyspnea. Because it is commonly associated with heart failure, tests that may be run mainly focus on measuring the function and capability of the heart.

The resulting constriction and inflammation causes a narrowing of the airways and an increase in mucus production; this reduces the amount of oxygen that is available to the individual causing breathlessness, coughing and hypoxia. Bronchospasms are a serious potential complication of placing a breathing tube during general anesthesia.
Asthma phenotyping and endotyping has emerged as a novel approach to asthma classification inspired by precision medicine which separates the clinical presentations of asthma, or asthma phenotypes, from their underlying causes, or asthma endotypes. The best-supported endotypic distinction is the type 2-high/type 2-low distinction.
The word paroxysm means 'sudden attack, outburst' [2] and comes from Greek παροξυσμός (paroxusmós) 'irritation, exasperation'. [3] Paroxysmal attacks in various disorders have been reported extensively, and ephaptic coupling of demyelinated nerves has been presumed as one of the underlying mechanisms of this phenomenon. This is ...
It might be expected that people with EIB would present with shortness of breath, and/or an elevated respiratory rate and wheezing, consistent with an asthma attack. However, many will present with decreased stamina, or difficulty in recovering from exertion compared to team members, or paroxysmal coughing from an irritable airway. [ 2 ]
