Relative effects of forced vital capacity and ALSFRSâR on survival in ALS
Muscle and Nerve, 2021Amyotrophic lateral sclerosis (ALS) is a degenerative neuromuscular disease with marked clinical heterogeneity. This heterogeneity can be partly captured by clinical measures, such as the forced vital capacity (FVC) and ALS Functional Rating Scale ...

Vital capacity can be measured as forced vital capacity (FVC), slow vital capacity (SVC), and inspiratory vital capacity (IVC). Although it is well known that the latter two are generally greater, a systematic comparison of the three in subjects with different degrees of airways obstruction has not been made.

Effect of posture on vital capacity
Journal of Applied Physiology, 1986The influence of some extreme body postures on vital capacity (VC) was examined in young adult humans. Two postures required full support of body weight by the arms: arms up, hanging from a bar, and arms down with hands gripping parallel bars. Three involved muscles that flex and extend the trunk: a partial sit-up position while supine and nearly ...

The Vital Capacity in Pulmonary Emphysema
Annals of Internal Medicine, 1964Excerpt It is commonly believed that the vital capacity of patients with obstructive or bullous pulmonary emphysema is more or less diminished; mild emphysema is supposed to be accompanied by sligh...

It has been recognized that climates with a low relative humidity give relief to some patients with asthma. Inferentially this is due, at least in part, to the beneficial effect of dry air, which will extract more moisture from the bronchial tree than the air of a locality with a higher humidity.

Fall in vital capacity with posture
British Journal of Diseases of the Chest, 1985In a study of 147 subjects (50 normals, 50 with obstructive, and 47 with restrictive lung function), the mean reduction in forced vital capacity from standing to supine (delta FVC) was 7.5% (SD +/- 5.7), 11.2% (+/- 13.4), and 8.2% (+/- 7.7) respectively, with no significant difference between groups. The respective 95% upper confidence limits were 19%,

Vital Capacity and Timed Vital Capacity in Normal Men Over Forty
Journal of Applied Physiology, 1956The vital capacity and the 1-second timed vital capacity were measured on 428 healthy men between the ages of 40 and 88 who were living in a rural area of Massachusetts and who came voluntarily for...

Determinations of vital capacity, heretofore utilized chiefly by physiologists or restricted to the study of serious cardiac or pulmonary disabilities, are now finding a wider application. The ease with which this accurate information is accumulated has greatly facilitated the dissemination of its practical value.
