Radial pressure may underestimate central aortic pressure post-CPB; small cohort leaves open need for prospective validation before practice change.
Does radial artery pressure accurately reflect central aortic pressure immediately following cardiopulmonary bypass?
Radial artery pressure significantly underestimates central aortic pressure by 12-32 mmHg in the immediate 10-60 minutes following cardiopulmonary bypass.
Stern et al. (1985) studied this question.
