Due to a large inter-subject variation of PIMAX, predicted values, however, maximal inspiratory mouth pressures are not suitable to define the individual expected normal PIMAX. What is the lower limit of the normal range? Methods: PIMAX has been prospectively measured in a representative sample of...
Prevalence and risk factors of airflow obstruction in an elderly Chinese population As the FEV(1)/FVC ratio falls with age, the lower limit of normal range (LLN), defined as the bottom 5% in a health reference population, of FEV... FWS Ko,J Woo,W Tam,... - 《European Respiratory Jo...
The recent European guidelines recommend using values below 80% predicted as indicating abnormal LF rather than the lower limit of normal (LLN). Objectives: To assess how the choice of a cut-off point (80% predicted vs. LLN at -1.645 SD) affects the incidence of functional disorders and ...

the lower limit of normal (LLN) of FEV1/FVC to define airflow obstruction. Determining the impact of these different cut-off levels in people living at high altitudes has not been studied. We assessed the prevalence of airflow obstruction and its clinical characteristics in residents living ...
For years, 120 mmHg has been considered the normal upper limit for systolic blood pressure in adults. Persistent elevations above this limit amount to hypertension–which is well known as the key risk factor for common cardiovascular diseases, such as heart attack,heart failure, and stroke. ...
