Datos presentados como media ± desviación estándar y mediana [percentil 25-75%]. PP = posición prona. PS = posición supina. IMC = índice de masa corporal. APACHE II = acute physiology and chronic health evaluation. SOFA = sequential organ failure assessment. Ppico = presión máxima. Ppl = presión plateau. DP = driving pressure. Cst = compliance estática. Iox = índice de oxigenación. * Indica diferencias estadísticamente significativas. |
