The aim of the Task Force was to derive continuous prediction equations and their lower limits
of normal for spirometric indices, which are applicable globally. Over 160,000 data points …

Field walking tests are commonly employed to evaluate exercise capacity, assess prognosis
and evaluate treatment response in chronic respiratory diseases. In recent years, there has …

This systematic review examined the measurement properties of the 6-min walk test (6MWT),
incremental shuttle walk test (ISWT) and endurance shuttle walk test (ESWT) in adults with …

… Correspondence and requests for reprints should be addressed to Bruce H. Culver, MD,
Division of Pulmonary, Critical Care and Sleep Medicine, University of Washington School of …

This international task force report updates general considerations for bronchial challenge
testing and the performance of the methacholine challenge test. There are notable changes …

We quantified the mechanical work of breathing in six normal subjects during assisted
mechanical ventilation. Using two volume-cycled ventilators of different design, we investigated …

To investigate the contribution of local mechanical factors to the alteration in ventricular
function that occurs during ventilation with positive end-expiratory pressure (PEEP), the …

Recently, this international task force reported the general considerations for bronchial
challenge testing and the performance of the methacholine challenge test, a “direct” airway …

Lung function parameters vary considerably with age and body size, so that, unlike many
laboratory tests, the normal range of expected values must be individualized. For spirometry, …

The muscles of respiration comprise three groups: the diaphragm, the intercostal and accessory
muscles, and the muscles of the abdomen (Fig 1). All three groups have inspiratory and …
