Why the study?
Does primary change in mean arterial pressure influence calculated aortic impedance in a canine model?
Does primary change in mean arterial pressure influence calculated aortic impedance in a canine model?
Changes in mean arterial pressure primarily affect wave reflection parameters rather than windkessel parameters in the systemic arterial system.
No takes yet. Share an insight, caveat, or question.
MAP effects on canine aortic impedance are reflection-driven; leaves open translation to human hemodynamics and clinical impedance assessment.
Alexander et al. (1989) studied this question.
