Each person may have a personal best that is higher or lower than the average. hand bailer

Forced Expiratory Volume (FEV1) - Verywell Health

WebPulmonary function tests, or PFTs, measure how well the lungs work. For some of the test measurements, the client can breathe normally and quietly. Other tests require forced inhalation or exhalation after a deep breath. Sometimes, they will be asked to inhale a different gas or a medicine to see how it changes test results. WebSome authors have shown that PEFR monitoring is a reasonably precise measurement tool for measuring airflow obstruction in COPD patients. 5 In addition, the compliance rate of daily PEFR use in COPD patients has been >90% in recent studies, making it a potentially useful monitoring modality. 6 A good correlation between forced expiratory volume in 1 … WebCheck that the patient has a baseline peak expiratory flow rate (PEFR). Obtain this either from their records - a personal best recorded within the last two years - or, if they have not measured their PEFR within the last two years, calculate it from a predicted PEFR chart.
