Management of acute severe asthma

Critical Care Nursing Clinics of North America
Adam C Winters

Abstract

Asthma is a chronic inflammatory disorder that results in recurrent episodes of reversible airflow obstruction. Lung hyperinflation results from obstruction or dynamic airway collapse during exhalation. Obstruction and dynamic hyperinflation both play a deleterious role in asthma. Patients who present with asthma have increased inspiratory work of breathing due to lung hyperinflation and auto-positive end-expiratory pressure (auto-PEEP). The goal of acute care treatment is to reverse bronchoconstriction and inflammation, thus reducing dynamic hyperinflation, so that breathing is restored to baseline, unlabored, quiet breathing.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here
