Peak Expiratory Flow Rate - University of Glasgow
www.gla.ac.ukPeak expiratory flow is a simple and easy, yet essential diagnostic tool used to assess asthma severity. Peak flow is also an important measure of the effectiveness of treatment with bronchodilator therapy. Peak flow meters (EU/EN ISO standard) are handheld devices used to measure PEFR in the ambulatory setting. ...
