title: [Lung volume and airway resistance in healthy schoolchildren in Zurich--normal values].
abstract: Total- and vital capacity (TC, VC), FIV1, FEV1 and airway resistance were determined in 45 boys and 44 girls aged 8 to 12 years with the aid of body-plethysmography. 2. VC correlates best with body height. Boys have a 200 ml greater VC than girls. Beginning with 12 to 13 years, age is an additional factor modifying VC. 3. The ratio VC/TC averages 0.835 in boys and 0.824 in girls, the ratio is independent of the VC. 4. Airway resistance is appreciably higher than in adults and decreases with rising VC and body growth. 5. FIV1 is 87%, FEV1 is 80% of VC. These values are independent of sex and VC.
