Normal Standards for Single Breath Tests of Ventilatory Capacity in Children

Normal standards for single breath tests of ventilatory capacity in children.

Tests of ventilatory capacity based on the recording of a maximum forced expiration after a full inspiration are becoming increasingly widely used. They are quicker to perform and require less cooperation and effort on the part of the subject than the conventional maximum breathing capacity estimation, and the results are more informative because three indices of ventilatory capacity, each of d...

The ventilatory capacity of normal children.

The study of pulmonary diseases in children is handicapped by the few relevant objective measurements which can be made. Radiological findings may remain unchanged for years and usually the only available indications of improvement or deterioration are the child's general appearance, weight, loss of schooling, and other non-specific information. Few functional measurements of the lungs have bee...

Normal Predicted Values of Single-Breath Diffusing Capacity of the Lung in Healthy Nonsmoking Adults

Single breath diffusing capacity for carbon monoxide in stable asthma.

BACKGROUND Single breath diffusing capacity for carbon monoxide (Dco) is commonly used as a simple method of assessing overall pulmonary gas exchange properties. Studies of Dco in bronchial asthma have yielded conflicting results. OBJECTIVE To study Dco and to determine the factors influencing Dco in patients with asthma. METHODS Dco was prospectively measured in 80 consecutive never-smoker...
