Gas exchange with copd
WebThe preserved overall gas exchange capacity (RBC/Gas) despite the abnormally low Tissue/Gas indicates that a disproportionally higher amount of xenon in the alveolar-interstitial tissues is picked up by the capillary RBCs, likely due to increased pulmonary capillary perfusion (“hyperemic capillaries”). WebBreathing, obstruction, restriction, and gas exchange (BORG) workshop whiteboard minilecture (WML). Panel (A) is the Breathing module, panel (B) is the Obstruction module, panel (C) is the Restriction module, and panel (D) is the Gas exchange module. An interactive WML illustrates the BORG framework.
