Understanding Asthma – pathophysiology and treatment

Asthma explained: understand causes, triggers, symptoms, diagnosis, and practical treatment steps to manage acute and chronic attacks. This concise video breaks down asthma’s inflammatory mechanisms, common triggers (allergens, smoke, cold air, medications, exercise), and why bronchial hyper-responsiveness leads to wheeze, cough, and breathlessness.

You’ll learn how asthma develops—from airway inflammation, mucus hypersecretion, and smooth-muscle contraction to possible long-term airway remodeling—and how genetics and environmental exposures interact. The video outlines clear diagnostic approaches for children and adults, including history, response to bronchodilators, and pulmonary function testing. Follow a stepwise treatment framework covering relievers (salbutamol and antimuscarinic inhalers), preventers (inhaled corticosteroids and combination inhalers), and advanced options such as montelukast and monoclonal antibodies targeting eosinophils.

Practical value: recognize avoidable versus unavoidable triggers, master inhaler technique, and implement an asthma action plan to prevent escalation. The guide describes how to assess acute exacerbation severity—from mild (able to speak in full sentences, SpO2 >94%) to life-threatening (cyanosis, reduced consciousness, SpO2 <90%)—and the appropriate escalation: bronchodilators, systemic corticosteroids, and rescue therapies like magnesium sulfate, adrenaline, non-invasive ventilation, or intubation when needed.

Packed with clinical insights and actionable steps, this video equips caregivers and patients to spot warning signs, improve control, and reduce the risk of chronic airway remodeling.
