Asthma is a chronic inflammatory disease of the airways characterized by variable and recurring symptoms of wheezing, coughing, chest tightness, and shortness of breath. It affects over 26 million people worldwide each year and causes over 4000-6000 deaths annually in India alone. The disease is managed through medications like bronchodilators and anti-inflammatory drugs administered via inhalers or nebulizers. Nursing care involves monitoring vitals, managing symptoms, preventing exposure to triggers, teaching patients about treatment and providing breathing exercises.
