Spearman's r for distending pressure and VT.Results Distending pressure and VT correlated in cadaver piglets (r=0.83, p<0.001), manikin (r=0.98, p<0.001) and combined data (r=0.49, p<0.001). VT was delivered during chest recoil during CC in both models. In cadaver piglets, a distending pressure ∼25 cm H2O was needed to achieve an adequate VT.Conclusions Chest recoil generates VT depending on an adequate distending pressure. This has previously been demonstrated in adult animals. A pressure of ∼25 cm H2O is needed to achieve an adequate VT delivery.
