Changes in intrapulmonary shunt (Qs/Qt), arterial blood pressure (MABP), and heart rate (HR) in surfactant (SF)‐deficient newborn piglets treated with SF administered by the INSURE method or LISA using a nasogastric tube (NT) or LISAcath®. Mean Qs/Qt (A), MABP (B), and HR (C) values in the INSURE (black square), LISA‐NT (white square) and LISAcath® (white circle) groups. (*)P < 0.05 versus INSURE group (one‐way ANOVA). Values are mean ± SD. BAL, bronchoalveolar lavage; ST, stabilization
