Dead space anatomy and physiology2/13/2024 Before the VQ Mismatch, There Was a VQ Matchįor normal gas exchange to occur, oxygen within the lungs has to move into the bloodstream and carbon dioxide within the bloodstream has to move into the lungs. The difference in pathophysiology between a shunt and dead space is essentially why oxygen therapy works wonders in some patients but has a minimal effect on others. But how hypoxemia reacts to oxygen therapy is different based on whether the patient has a shunt or dead space the two problems associated with a VQ mismatch. The management for hypoxemia seems easy enough provide oxygen therapy as quick band-aid therapy to counteract the problem. Ventilation may exceed perfusion in parts of the lung resulting in increased physiological dead air space.Hypoxemia is an abnormally low concentration of oxygen in the blood which can lead to dire consequences when left untreated. Air may reach the periphery of the lungs but fail to make contact with the capillary blood.
