Intravenous dihydropyridine calcium channel blockers can quietly worsen oxygenation by blunting hypoxic pulmonary vasoconstriction. In this episode, we break down the bedside mechanism, which agents are implicated, who’s at highest risk (post-op atelectasis, obesity, pneumonia, focal ARDS, COPD), how soon it happens, and exactly what to do.
