Clinicians should interpret post-CPB radial pressures with caution; leaves open the contribution of hand vascular resistance to gradients and need for validation.
Does wrist compression alter the radial artery-to-aorta pressure gradient after cardiopulmonary bypass?
Wrist compression restores the higher radial artery systolic pressure after cardiopulmonary bypass, suggesting the post-CPB radial-to-aorta pressure gradient is related to reduced hand vascular resistance.
Pauca et al. (1989) studied this question.
