Vital capacity and height

It is the sum of tidal volume, inspiratory reserve volume. A number of physiological factors like age, gender, height and ethnicity effect lung volumes. The reference values of lung volume and capacities were calculated previously and . Relationships between vital capacity , height and nasal airway resistance in asymptomatic volunteers.

It is equal to the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume. In combination with other physiological . He was the first person to use the word “ spirometer” to describe his instrument and the first to use the term “ vital capacity ” to designate the maximum amount of air an individual can exhale . These data were used to predict normal values for vital capacity in patients with spinal de- formity. The mean values for subjects younger than years showed the relationship to be as . Calculates estimated vital capacity from your age and height. It is intended for people over the age of 18.

Measurements of vital capacity and total lung capacity were made on healthy men of heights up to 2cm. In the range between 1and 2cm. From the age of to 3 the vital capacity of both sexes remains at the same level, while later it decreases considerably. The vital capacity correlates with longitudinal dimensions, particularly with the height , . Vital capacity is affected by age and body size.

Most of the regression equations of predicted vital capacity are based on age and body height. But the vital capacity divided by height correlates remark. The lung volumes correlated well with the cube of height.

NORMAL STANDARDS FOR LUNG VOLUMES. We follow the prac- tice in previous papers on this subject of giving total rather than partial correlation coefficients. This means, for example, that the correlation of vital capacity with height is that directly calculated from the pairs of values for . A negative correlation is obtained in relation to all circumference dimensions of females and the waist circumference of males.

OBJECTIVES: The objectives of this study were to determine the degrees of association between the Forced Vital Capacity (FVC) with four anthropometric variables: height , sitting height , surface, and body volume, and two somatometrics indexes: Body Mass Index (BMI) and Cormic index, and to confront the values of FVC . Determination of the residual volume is more difficult as it is impossible to completely breathe out.
