Abstract
Lung function in 30 children born prematurely have been followed for two years. Group I (BW 1232±83 g, GA 27.8±0.5 wks) had been treated for severe respiratory distress syndrome (RDS) in the neonatal period with mechanical ventilation for 28±4.6 d (mean±SEM). Group II (BW 2181±333 g, GA 33.0±1.2 wks) had mild or no RDS. Infants were studied at 50 and 120 wks corrected age. Total respiratory system compliance (CRS) and static resistance (RSt) were measured by occlusion technique (PEDSR). PPO was measured as VMax FRC (ml/sec)/cm body height by partial FEF with jacket compression (squeeze) technique (PUFFSR). Data given as mean±SEM.
No significant group differences in CRS and RSt could be found. FEF revealed significant PPO in Group I. FEF is a better method for demonstration of pulmonary obstruction in small children than measurements of static resistance.
