Evaluation of the Peak Expiratory Flow Rate

Scandinavian Journal of Clinical and Laboratory Investigation, 1973
48 children, 37 with bronchial asthma, exhaled into Wright's Peak Flow Meter 10 consecutive times. A mathematical model was constructed in an attempt to make comparisons between the characteristics of five different methods for evaluating the PEF.

How to use peak expiratory flow rate

Archives of disease in childhood - Education & practice edition, 2017
Asthma is the most common chronic disease of children worldwide.1 The most recent National Institute for Health and Care Excellence asthma guidelines explicitly state that asthma should not be diagnosed on symptom history alone. It calls for spirometry and peak expiratory flow rate (PEFR) assessment to assist in making the diagnosis.

Peak Expiratory Flow Rates in Possible Occupational Asthma

Chest, 1991
Objective criteria for interpretation of peak expiratory flow rate readings were assessed in 50 patients evaluated for suspected occupational asthma who had at least two weeks of PEFR readings and an objective diagnosis based on other investigations. The prevalence of OA was 36 percent.

PEAK EXPIRATORY FLOW RATE IN AN ELDERLY POPULATION

American Journal of Epidemiology, 1989
A population survey was conducted in 1982-1983 among 3,812 persons aged 65 years and older residing in East Boston, Massachusetts, a geographically defined urban community. Three measurements of peak expiratory flow rate were obtained by using calibrated mini-Wright meters.

Peak Expiratory Flow Rate In Cigarette Smokers

Highland Medical Research Journal, 2005
Objective: To compare lung function between smokers and non-smokers using Peak Expiratory Flow Rate (PEFR). Methods: This study examines the peak expiratory flow rate (PEFR) of three hundred and forty cigarette smokers, age and sex-matched with PEFR of equal number of non-smokers. Results: The mean PEFR of all smokers (males and females) was 225.0 + 62.

Use of Peak Expiratory Flow Rates in Treating Patients

Archives of Pediatrics & Adolescent Medicine, 1986
Sir .—We found the article by Sly et al 1 to be very important. In a similar study that was carried out a few months ago in Greece, we checked the reliability of diary cards compared with peak expiratory flow rates (PEFR) measured at home by 33 asthmatic children aged 6 to 11 years (mean, 8.2 years).

Factors affecting the peak expiratory flow rate in children

British Journal of Diseases of the Chest, 1984
Standing height and peak expiratory flow rate (PEFR) were measured in 339 British schoolchildren aged 7-16 years. Enquiry was made into a past history of wheeze or atopy, a family history of asthma or atopy, or a cold within the preceding 2 weeks. A strong correlation was found between PEFR and height, expressed by the equation PEFR = 5.640 Ht - 472.5 (

Definition of Respiratory Sarcopenia With Peak Expiratory Flow Rate

Journal of the American Medical Directors Association, 2019
Respiratory muscle strength decreases with advancing age, and respiratory muscle dysfunction may indicate respiratory sarcopenia. However, there is no consensus regarding the definition of respiratory sarcopenia. We aimed to create a definition of respiratory sarcopenia based on the peak expiratory flow rate (PEFR).Cross-sectional study.Community-based

Peak expiratory flow rate and rate of change of pleural pressure

Respiration Physiology, 1973
Abstract It has been suggested that the sudden collapse of the large intrathoracic airways occurring at the onset of a forced expiratory manoeuvre produces an airflow contributing appreciably to the peak expiratory flow rate (PE/.VR). If so, one expects that PE/.VR will depend, not only on alveolar pressure, but also on the rate of change of pleural ...

How to measure peak expiratory flow rate

Nursing Standard
Peak expiratory flow rate (PEFR) is an important test in the diagnosis and monitoring of respiratory conditions, especially asthma. PEFR measures the speed at which air is forcefully exhaled from full inspiration, expressed in litres per minute (L/min).
