Daily monitoring of peak expiratory flow (PEF) or forced expiratory volume in 1 second (FEV1) should not be performed routinely to monitor recovery from an exacerbation because the magnitude of changes is small compared with the variability of the measurement.

Men can have peak flow values as low as 100 liters/minute less than the average value shown and still fall within the normal range. Women can have peak flow values as low as 80 liters/minute less than the average value shown and still 5) What is a normal peak flow? A chart called a ‘nomogram’ can be used to estimate your predicted peak flow if you are male or female, your age and height. It is important to remember that everyone is different and you should be guided by what is normal for you. Measuring your peak flow when you feel well will establish your normal or best peak PEF L/min: 60: 84: 108: 133: 157: 181: 205: 230: 254: 278: 302: Height (cm) Units 145 150 155 160 165 170 175 180 185 190 195; VC L: 2.39: 2.62: 2.87: 3.14: 3.42: 3.71: 4.03: 4.35: 4.70: 5.06: 5.44: FVC L: 2.39: 2.62: 2.87: 3.14: 3.42: 3.71: 4.03: 4.35: 4.70: 5.06: 5.44: FEV1 L: 2.37: 2.60: 2.85: 3.12: 3.40: 3.69: 4.01: 4.33: 4.68: 5.04: 5.42: FEV1/VC: 0.99: 0.99: 0.99: 0.99: 0.99: 0.99: 1.00: 1.00: 1.00: 1.00: 1.00: FEF 25 … 2008-11-01 Peak expiratory flow (PEF) is the maximum flow achieved during a forced expiration starting from the level of maximal lung inflation.37 Primarily a measure of large airway caliber, PEF can be used to identify and assess airflow limitation in clinical practice and epidemiologic studies and can aid in the monitoring of disease progress and the effects of treatment. Values ranging from 50-60% and up to 130% of the average are considered normal.

Peak flow measurement is mostly done by people who have asthma. Peak flow measurement can show the amount and rate of air that can be forcefully breathed out of the Predictive Normal Values (Nomogram, EU scale) The change in scale for peak flow meters will result in PEF readings that are different, depending on whether the individual has used a Wright scale meter, or the new EU scale meter. Men can have peak flow values as low as 100 liters/minute less than the average value shown and still fall within the normal range. Women can have peak flow values as low as 80 liters/minute less than the average value shown and still fall within the normal range. The Estimated/Expected Peak Expiratory Flow (Peak Flow) quantifies asthma exacerbation severity. This is an unprecedented time. It is the dedication of healthcare workers that will lead us through this crisis.
