Peak expiratory flow is not a quality indicator for spirometry: peak expiratory flow variability and FEV1 are poorly correlated in an elderly population.
BACKGROUND Peak forced expiratory flow (PEF) and FEV(1) are spirometry measures used in diagnosing and monitoring lung diseases. We tested the premise that within-test variability in PEF is associated with corresponding variability in FEV(1) during a single test session. METHODS A total of 2,464 healthy adults from the Health, Aging, and Body Composition Study whose spirometry results met Ame...
متن کاملPeak expiratory flow rate in elderly Malaysians.
An epidemiological survey was conducted among 1,414 healthy ambulatory elderly persons aged 55 years and above in the Kuala Langat district, Selangor. The relationship between peak expiratory flow rate (PEFR), demographic variables, socioeconomic status, smoking, alcohol use and respiratory symptoms were examined. The peak expiratory flow declined with age and were lower in women of all ages. S...
متن کاملPeak expiratory flow rates in elderly Indians.
Peak expiratory flow rates were measured in 124 normal elderly men (55-85 yr) using the Wright's peak flow meter. In the less than 60 yrs age group (n = 32; mean age 57.7 yr) the PEFR was 431 +/- 13 lpm, while for the group greater than 60 yr (mean age 69.0 +/- 6.0; n = 92), the PEFR value was 373 +/- 11 1pm. These values are similar to those reported in other Indian studies, suggesting that th...
متن کاملCorrelates of peak expiratory flow lability in elderly persons.
OBJECTIVE To determine the correlates of the lability of peak expiratory flow (PEF) in the elderly. METHODS A community sample of 4,581 persons > or = 65 years old from the Cardiovascular Health Study completed an asthma questionnaire and underwent spirometry. During a follow-up examination of the cohort, 1,836 persons agreed to measure PEF at home twice daily for 2 weeks, and 90% successfull...
متن کاملPeak Expiratory Flow Rate in Healthy Children from Tehran
Background: Measuring peak expiratory flow rate has been suggested as an important tool in asthma management by all international guidelines. Objective: Studies on various populations have shown considerable variations in normal values of peak expiratory flow rate. Since reference standards for Iranian children are not available, the present study was performed to establish these standards. Me...
