Pressure and oxygen saturation curves during the first 12 h of postoperative care according to the presence (squares) or absence (circles) of respiratory viral genomes in nasopharyngeal (A–D) and tracheal (E–H) aspirates. Results are presented as means with SE. P values correspond to differences between groups analyzed using the general linear model for repeated measures after Box–Cox transformation of the dependent variables. O2 Sat: peripheral oxygen saturation; PAP and SAP: pulmonary arterial pressure and mean systemic arterial pressure, respectively; PAP/SAP: pulmonary/systemic arterial pressure ratio
