Lung damage due to pneumoconiosis cannot be reversed. [22] However, some steps can slow down disease progression and relieve symptoms. These include the prescription of medications and breathing treatments to open airways and reduce inflammation. [22] Pulmonary rehabilitation and supplemental oxygen may also be recommended. [22]
However, asthma is rarely the only symptom, and not all people with food or other allergies have asthma [17] Sulfite sensitivity Asthma can occur in reaction to ingestion or inhalation of sulfites, which are added to foods and wine as preservatives. [18] Salicylate sensitivity Salicylates can trigger asthma in sensitive individuals. Salicylates ...
Asthma is characterised, in part, by recurrent episodes of reversible airway obstruction; however, in some patients, a degree of irreversible airway obstruction develops over time, leading to lung function decline and fibrosis. Existing airway remodelling may also contribute to bronchoconstriction in acute asthma exacerbations. [1] [2]
As caffeine is a bronchodilator in people with asthma, the use of caffeine before a lung function test may interfere with the results. [98] Single-breath diffusing capacity can help differentiate asthma from COPD. [20] It is reasonable to perform spirometry every one or two years to follow how well a person's asthma is controlled. [99]
Obstructive conditions of the lower airway, including severe asthma or COPD episodes, can also lead to respiratory arrest. During these episodes, known as exacerbations, airway resistance is increased due to inflammatory changes in the lungs. This leads to increased work of breathing and decreased oxygen delivery to tissue.
Pulmonary drug delivery is mainly utilized for topical applications in the lungs, such as the use of inhaled beta-agonists, corticosteroids and anticholinergic agents for the treatment of asthma and COPD, the use of inhaled mucolytics and antibiotics for the treatment of cystic fibrosis (CT) and respiratory viral infections, [1] and the use of inhaled prostacyclin analogs for the treatment of ...
