The volume of trapped gas in healthy children aged 7–16

Abstract

Lung 156, 71 -77 (1979) In the article by E. Svenonius and R. Kautto, "The volume of trapped gas in healthy children aged 7-16" (LUNG 156 [1], 71 -77, 1979), there is an omission in Table 1, on p. 72. In column 2, "Range", the weight range for girls is 22.5-64. We regret this error. Ed.

Lung Function in Cystic Fibrosis

“…The children with CF were abnormal as regards VTG, VTG/TLQVo, VTG/VCVo, the applied tests in healthy children [15]. Table IV shows the number of abnormal subjects found with some lung function tests.…”

“…Table II presents the mean values and standard deviations (SD) of the lung func tion variables of the CF children in percent of predicted normal values [15] before sal butamol inhalation, and the change after salbutamol inhalation also in percent of pre dicted values.…”

“…The clinical data of the patients are presented in table I. [15] were calculated from the nitrogen washout. Thereafter, vital capacity (VC) and forced ex piratory volume in 1 s (FEV,) were measured with a high-fidelity spirometer (AB Kifa, Sweden).…”

“…The seated subject was connected to an equipment for measuring the functional residual capacity (FRC) with a multiple breath nitrogen washout technique [15] and the VTG which is the volume of nitrogen that can be mobilized by max imal breaths at the end of the N2 washout down to 2%, but expressed as air volume [9].…”
