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 ...
Reactive airway disease (RAD) is an informal label that physicians apply to patients with symptoms similar to those of asthma. [1] An exact definition of the condition does not exist. [ 1 ] [ 2 ] Individuals who are typically labeled as having RAD generally have a history of wheezing, coughing, dyspnea , and production of sputum that may or may ...
ACO presents with symptoms of both asthma and COPD. [1] ACO presents in adulthood, usually after the age of 40 (after there has been significant tobacco smoke or other toxic fumes exposure), with symptoms of dyspnea (shortness of breath), exercise intolerance, sputum production, cough and episodes of symptomatic worsening known as exacerbations.
[9] [10] Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. [3] These may occur a few times a day or a few times per week. [4] Depending on the person, asthma symptoms may become worse at night or with exercise. [4] Asthma is thought to be caused by a combination of genetic and environmental factors. [3]
Aspirin-exacerbated respiratory disease (AERD), also called NSAID-exacerbated respiratory disease (N-ERD) or historically aspirin-induced asthma and Samter's Triad, is a long-term disease defined by three simultaneous symptoms: asthma, chronic rhinosinusitis with nasal polyps, and intolerance of aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs).
This is a shortened version of the eighth chapter of the ICD-9: Diseases of the Respiratory System. It covers ICD codes 460 to 519. The full chapter can be found on pages 283 to 300 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
The goal of asthmatic agents is to reduce asthma exacerbation frequencies and related hospital visits. Anti-asthmatic agents as rescue medications for acute asthma attacks include short-acting β 2 -adrenergic receptor agonists (SABA), short-acting muscarinic antagonists (SAMA), systemic glucocorticoids , and magnesium sulfate .
Because of the wide differential diagnosis of exertional respiratory complaints, the diagnosis of exercise-induced bronchoconstriction based on history and self-reported symptoms alone has been shown to be inaccurate [6] [7] and to result in an incorrect diagnosis more than 50% of the time. [8]
