RESUMEN

La difusión pulmonar de monóxido de carbono (DL,CO, por sus siglas en inglés), también referida como factor de transferencia de monóxido de carbono (TL,CO), se usa para evaluar la transferencia de oxígeno desde el espacio alveolar hasta la hemoglobina de los eritrocitos contenidos en los capilares pulmonares. En este manuscrito abordamos los principios fisiológicos de la prueba de DL,CO con la técnica de una sola respiración (DL,COsb) y emitimos recomendaciones, tanto para su ejecución como para su interpretación. El procedimiento se apega al estándar vigente publicado en 2005 por la Sociedad Americana del Tórax y la Sociedad Respiratoria Europea.

PALABRAS CLAVE

Difusión pulmonar de monóxido de carbono, COsb, pruebas de función pulmonar.
