Study Notes

Asthma Definition and Risk Factors

Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to difficulty breathing, coughing, and wheezing.
Risk factors for asthma include family history, exposure to tobacco smoke, exposure to occupational triggers, and exposure to air pollution.

Types of Asthma

There are several types of asthma, including allergic asthma, non-allergic asthma, exercise-induced asthma, occupational asthma, and childhood-onset asthma.
Each type has unique triggers and characteristics.
Exercise-induced asthma is triggered by physical exertion, cold, dry air, and exposure to airborne allergens during exercise.
Allergic asthma is triggered by allergens and can cause symptoms such as wheezing, coughing, and shortness of breath.
Non-allergic asthma may be triggered by factors like stress or anxiety.

Asthma Pathophysiology

The obstruction in asthma is often due to the tightening of the muscles around the airways, inflammation, and the production of excess mucus.
This obstruction contributes to the characteristic symptoms of asthma, such as wheezing, coughing, and shortness of breath.

Early and Late Stage Asthma Response

In the early-stage asthma response, exposure to triggers leads to the release of inflammatory substances, causing airway constriction and symptoms such as coughing, wheezing, and shortness of breath.
In the late-stage response, further inflammation and mucus production can worsen airway obstruction, leading to prolonged or severe symptoms.

Clinical Manifestations of Asthma

Clinical manifestations of asthma include coughing, wheezing, shortness of breath, chest tightness, and increased mucus production.
These symptoms can vary in severity and frequency among individuals with asthma.

Pathological Changes in the Airway

The clinical manifestations of asthma, such as coughing, wheezing, and shortness of breath, are directly related to the pathological changes in the airways, including inflammation, airway hyperresponsiveness, and obstruction.
These changes contribute to the characteristic symptoms experienced by individuals with asthma.

Features of Asthmatic Airways

The three major features of asthmatic airways are airway inflammation, airway hyperresponsiveness, and airway obstruction.
Airway inflammation is often treated with inhaled corticosteroids, which reduce swelling and mucus production in the airways.
Airway hyperresponsiveness refers to the increased sensitivity of the airways to various triggers, leading to exaggerated narrowing of the air passages.
Airway obstruction refers to the narrowing of the air passages, making it difficult for air to move in and out of the lungs.
