Exhaling as quickly and forcibly as possible through the mouthpiece of the device evaluates the degree of airway narrowing by measuring the volume of air that can be exhaled in one breath. Use of the device permits self-management and provides information to guide and evaluate treatment. (Option B) The client moves the indicator on the numbered scale to 0 or to the lowest number on the scale before using the device. (Option C) The personal best reading is the highest peak flow reading the client can attain, usually over a 2-week period, when asthma is in good control. (Option D) The peak flow meter is used after a short-acting bronchodilator rescue MDI to evaluate response, not after a corticosteroid MDI. Educational objective: The peak flow meter is used to measure PEFR and is most helpful for clients with moderate to severe asthma. A reading is obtained by exhaling as quickly and forcibly as possible through the mouthpiece of the device.
