FRAGMENTO

La capacidad residual funcional es el volumen de gas que queda en el pulmón luego de una espiración normal. Corresponde a la suma del volumen residual (VR) más el volumen de reserva espiratoria (VRE). Es una medida del volumen pulmonar en reposo. Equivale aproximadamente al 4% o a 40 mL/kg del peso corporal ideal, es decir, alrededor de 2,800 mL en el adulto de 70 kg. La CRF es funcionalmente muy importante puesto que se relaciona directamente con el volumen de intercambio de gases y por lo tanto con la oxigenación; pero asimismo está involucrado con las propiedades elásticas del pulmón, es decir, la complacencia del sistema respiratorio y con la alteración de la resistencia vascular pulmonar.
