They have secured support from the National Heart, Lung, and Blood institute to randomize a new cohort and measure newborn forced expiratory flows as the primary outcome, she said.
1]), forced expiratory flow at 50 and 75 per cent of the vital capacity (FEF 50 and 75%), forced expiratory flow between 25 and 75 per cent of the vital capacity ([FEF.
25-75], forced expiratory flow rate at 25-75% of vital capacity.
Pulmonary function was also assessed by measuring the forced expiratory flow during the middle half of the FVC (FE[F.
Results: The investigators found that the vitamin supplements protected the study group from the decreases in forced expiratory flow, the amount of air dispelled from the lungs during a certain time period and peak expiratory volume, a measure of airway resistance, that were seen among those who received placebo pills.
