Objetiva, aceptable, repetible y útil, la espirometría continúa siendo un elemento diagnóstico fundamental en la atención del enfermo respiratorio. Muy a pesar de los avances en la informática que han facilitado su uso e interpretación, continúa siendo poco utilizada en consultorios y hospitales. Este artículo pretende introducir al lector con los elementos teóricos fundamentales para su interpretación, al mismo tiempo comprender sus limitaciones e indicaciones con el objeto de facilitar y estimular su empleo. Finalmente se enfoca el momento de indicar otras pruebas diagnósticas complementarias más sofisticadas, con el afán de contribuir a ofrecer un diagnóstico precoz y al tratamiento efectivo del enfermo respiratorio
PALABRAS CLAVE
Espirometría, enfermedad respiratoria.
