Post CPB Pump failure

Physiologically speaking, is it possible to be in Bi-ventr failure with a widened pulse pressure? Btw, this is in context of weaning from cpb

Common school of thought is Low stroke volume > high svr-> low pp

However, with a high svr, you lose your vascular distensibility and diastolic augmentation from the reflected wave.

Are both possible?


Thanks in advance.

sure, its possible. id wager your SVR isnt as high as you think it is while weaning CPB

I guess you saw it in the OR and hence your question.

Were you monitoring peripheral or central bp, radial vs aortic?
