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

Diurnal Variation in Peak Expiratory Flow and Forced Expiratory Volume [PDF]
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

Raised-Volume Forced Expiratory Flow-Volume Curve in Healthy Taiwanese Infants [PDF]
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.

Prediction equations for spirometry in four‐ to six‐year‐old children
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]
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]
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.

Forced expiratory flow‐volume relationships [PDF]
Forced expiratory flow-volume relationships have been used to investigate changes in lung mechanics caused by upper abdominal operations. The slope of the 'effort independent' portion of the flow-volume curve increases after operation, suggesting that restriction of respiratory movement is associated with an increase in lung recoil.

Introduction Acute respiratory infections (ARIs) in infancy may have a long-term impact on the developing respiratory system. We planned a prospective cohort study to determine the impact of ARI during infancy on the pulmonary function test indices at 3 ...

UTILITY OF SPIROMETRY IN ASSESSMENT OF UPPER AIRWAY OBSTRUCTIONS: THE NEGLECTED PARAMETERS
Upper airway obstructions represent a huge burden to the health care system due to its high morbidity and cost to the economic systems. Therefore, it is important to understand the physiological parameters used in diagnosis and prognosis of these ...
