This comprehensive guide details severe asthma diagnosis and management strategies, including critical assessments, emergency treatments, and lifestyle modifications. It aims to educate patients and caregivers on managing this complex respiratory condition effectively for better health outcomes.

Understanding and Addressing Severe Asthma

Severe asthma impacts around 24 million people nationwide and lacks a universal definition. It is a complex lung disorder that often requires high-dose inhaled corticosteroids and systemic drugs. The World Health Organization categorizes severe asthma into three levels: WHO Class I includes uncontrolled, untreated cases; Class II covers uncontrolled asthma due to adherence issues or ongoing triggers; and Class III involves cases manageable only with maximum therapy.

Treating severe asthma can be difficult because it often shows resistance to common medications, known as therapy-resistant asthma. This form responds poorly to corticosteroids and standard treatments.

Diagnosing Severe Asthma
Diagnosis in individuals over five years old involves lung function tests. Poor results hint at inadequate control. Important assessments include:

Spirometry
Evaluates lung capacity by measuring air expelled forcefully after deep inhalation.

Pulse oximetry
Measures blood oxygen saturation, especially during severe attacks.

Nitric oxide testing
Detects nitric oxide levels in breath, indicating bronchial inflammation.

Peak expiratory flow
Measures the speed of exhalation, useful during emergencies.

Handling Severe Asthma Attacks
After diagnosis, treatment depends on symptoms and emergency action plans. Initial response often includes inhalers with quick-relief medications like albuterol. Children may need nebulization support. If symptoms continue beyond 20 minutes, emergency measures are necessary, such as:

Oral corticosteroids
Lower lung inflammation; given orally or intravenously in critical cases.

Intubation
Inserting a breathing tube to assist respiration during life-threatening episodes, alongside medication.

Ipratropium (Atrovent)
A bronchodilator used if albuterol alone isn't enough.

Preventive inhalers
Contain corticosteroids to lower inflammation and prevent future attacks.

Additional therapies
Medications combined with preventers and relievers to enhance lung function and control symptoms.

Patients are closely monitored in emergencies to prevent relapse. Cases unresponsive to initial treatment may require hospitalization with continuous medication. Lifestyle changes such as avoiding triggers, quitting smoking, and minimizing environmental irritants are crucial for effective management.
