Neonatal Pulmonary Vasculture: Recovery from Positive End—expiratory Pressure (peep) in Impact and Isolated Lungs

Abstract

Unilateral PEEP (UPEEP) reduces ipsilateral pulmonary blood flow (PBF) in the intact (INT) newborn lamb. On cessation of UPEEP, ipsilateral PBF returns slowly to baseline. Intact and isolated lungs of 9 infant lambs were studied to examine the mechanism of this vascular hysteresis.Flow probes were placed on R and L pumonary arteries (PA) of 4 infant lambs… (More)
