RESUMEN
El síndrome de insuficiencia respiratoria aguda (SIRA) es una afección grave que presenta el enfermo en estado crítico, esto es condicionado a la respuesta inflamatoria del agente etiológico en la barrera endotelio-epitelial pulmonar inducida por inflamación, cuyo resultado condiciona aumento de la permeabilidad vascular y disfunción del agente tensoactivo con lo que se producen grados variables de colapso y consolidación alveolar. Con la finalidad de disminuir el daño inducido por ventilación mecánica, se han elaborado diferentes estrategias. La estrategia más aceptada y avalada por evidencia científica es la ventilación de protección pulmón. En los últimos años, la presencia de removedores de CO
2 extracorpóreos sin el uso de bombas arteriovenosas se han desarrollado y probado para su uso clínico, su uso permite la remoción de CO
2 con una mejoría moderada de la oxigenación. Una estrategia con ventilación mecánica con volumen corriente ultrabajo (3 mL/kg de peso predicho) en combinación con los dispositivos de extracción de CO
2 podrían reducir la lesión pulmonar asociada con la ventilación en comparación con el manejo protector actual. Aún se debe determinar si esta estrategia mejorara la sobrevida de los enfermos con SIRA.
