PEF varies throughout the day. In a person who does not have asthma, it may vary between 10% and 15%. In a person who has poorly controlled asthma, it may vary more than 20%. Peak expiratory flow rates are compared with charts that list normal values for sex, race, and height. Personal best However, FEV1 as a measure of asthma severity has advantages compared to PEF. These include greater accuracy, less effort dependence, better repeatability, and for some spirometers the availability of real-time graphics and quality assurance checks to confirm reliability of the re-sults.
