Diurnal Variation in Peak Expiratory Flow and Forced Expiratory Volume [PDF]
Journal of Clinical and Diagnostic Research, 2015 Introduction: Diurnal variability in airways has most commonly been reported using peak expiratory flow (PEF) and forced expiratory volume in one second (FEV1). Characteristics of variability in small, mid and large airways caliber are expected to be

Monaldi Archives for Chest DiseaseAccording to the Global Initiative for Chronic Obstructive Lung Disease criteria, the ratio of forced expiratory volume in the 1st second (FEV1) and forced vital capacity (FVC) is required to diagnose chronic obstructive pulmonary disease.

Raised-Volume Forced Expiratory Flow-Volume Curve in Healthy Taiwanese Infants
Scientific Reports, 2017 The raised-volume rapid thoracoabdominal compression (RVRTC) manoeuvre has been applied to obtain full forced expiratory flow-volume curves in infants. No reference data are available for Asian populations.

Proteomic associations with forced expiratory volume: a Mendelian randomisation study
Respiratory Research, 2023 Background A decline in forced expiratory volume (FEV1) is a hallmark of respiratory diseases that are an important cause of morbidity among the elderly.

Thoracic gas compression during forced expiration is greater in men than women
Physiological Reports, 2020 Intrapleural pressure during a forced vital capacity (VC) maneuver is often in excess of that required to generate maximal expiratory airflow.

Prediction equations for spirometry in four‐ to six‐year‐old children
Jornal de Pediatria (Versão em Português), 2016 Objective: To generate prediction equations for spirometry in 4‐ to 6‐year‐old children. Methods: Forced vital capacity, forced expiratory volume in 0.5 s, forced expiratory volume in one second, peak expiratory flow, and forced expiratory flow at 25–75%

Precipitous fall of the forced expiratory volume [PDF]
Thorax, 1969 Two patients are described who showed a precipitous loss of forced expiratory volume from normal to low levels within a few years. They did not have bronchial asthma and we suggest that this pattern of deterioration may occur occasionally in patients before they attend hospital with the symptoms of chronic bronchitis.

Variability of relaxed expiratory volume and forced inspiratory volume [PDF]
Thorax, 1970 Measurements of relaxed expiratory volume in one second (REV1·0) and forced inspiratory volume in one second (FIV1·0) were made on 50 subjects on two occasions to know the variability of these procedures in the individual subject. The mean coefficients of variation for REV1·0 and FIV1·0 were 6·74% and 8·92%, respectively.
