The guidelines for diagnosing and managing asthma are based on current science. Precise measurement of lung function to determine the severity of asthma and to monitor the course of therapy. Avoidance or elimination of factors that prompt asthma symptoms or exacerbations. Medications for reversal and long-term prevention of airway inflammation, plus medications to manage asthma exacerbations. A knowledgeable patient and family, working in partnership with health professionals.
Airflow obstruction is at least partially reversible.
Alternative diagnoses are excluded particularly COPD and vocal cord obstruction in adults, and aspiration and cystic fibrosis in children. Conduct spirometry before and after inhaled bronchodilator. When spirometry is normal but patients still have symptoms, follow up with peak flow monitoring for 1-2 weeks upon arising and in the afternoon before and after inhaled bronchodilator. Establish patient s personal best value and evaluate the response to changes in therapy. Patients with moderate persistent and severe persistent asthma may benefit from having a peak flow meter at home and measuring their level upon arising each morning.
