Episodio – Vasoconstricción hipóxica pulmonar y curva resistencia-O₂ | USMLE Step 1

from USMLE DREAMERS · host USMLE DREAMERS

En este episodio analizamos un experimento donde se mide la resistencia vascular en un órgano mientras se modifica el contenido tisular de oxígeno. La curva muestra que a menor O₂ tisular, mayor resistencia vascular, un comportamiento característico y casi exclusivo de la circulación pulmonar, donde la hipoxia provoca vasoconstricción hipóxica para optimizar la relación ventilación-perfusión.#USMLE #Step1 #FisiologíaRespiratoria #VasoconstriccionHipoxica #Pulmones #VentilacionPerfusion #GasExchange #USMLEDreamers
