In a random sample of 2,415 adults aged 18-70 yrs we measured reactivity to methacholine as the dose provoking a 20% fall (PD20) in one-second forced expiratory volume (FEV1), atopy as the mean skin wheal response to three ... J Britton,I Pavord,K Richards,... - 《European Respira...

How does the respiratory and urinary system work together to maintain acid-base balance in the body? What is(are) the function(s) of the respiratory system? How is the FVC and FEV1/FVC ratio impacted by respiratory disease? Why do people with chronic bronchitis have a high...
Since changes in RR mirror the changes in FEV1 we believe the ADP could be useful diagnostic tool to measure changes in airway caliber. The APD device using passive breathing will be especially helpful in young children or in any persons where spirometry is difficult or impossible to perform....
Spirometry measures two key factors: expiratory forced vital capacity (FVC)andforced expiratory volume in one second (FEV1). Your doctor also looks at these as a combined number known as theFEV1/FVC ratio. If you have obstructed airways, the amount of air you’re able to quickly blow out ...
