Preterm rabbit lung tissue mechanics: Maturational changes and effect of antenatal steroids KU Leuven
AIM:: Describe lung tissue and central airway mechanics using forced oscillation in preterm rabbits at different gestational ages and after maternal administration of betamethasone (BM). METHODS:: One hundred twelve fetuses from 54 does were studied. Ventilation was done using a Flexivent(R) (Scireq, Montreal, Canada). Resistance (Rrs), compliance/bodyweight (Crs/bw), Newtonian resistance (Rn), tissue damping (G(L)), and elastance (H(L)) were ...
