Decreasing cardiac output has many physiologic effects (hypotension, reflex tachycardia, decreased UOP, etc). But why does low CO worsen hypoxemia?

Recall that low CO drops the mixed venous O2 sat due to stagnant blood flow. If your SvO2 drops low enough it will worsen hypoxemia. This is the SIXTH cause of hypoxemia (which is often overlooked).

See my ICU OnePager on hypoxemia for more on this.
