Blood pressure and blood flow variation during postural change from sitting to standing: model development and validation

Olufsen, M. S., Ottesen, J. T., Tran, H. T., Ellwein, L. M., Lipsitz, L. A., & Novak, V. (2005, April 29). Journal of Applied Physiology, Vol. 99, pp. 1523–1537.

By: M. Olufsen n, J. Ottesen, H. Tran* , L. Ellwein*, L. Lipsitz & V. Novak

author keywords: cardiovascular system; mathematical modeling; cerebral blood flow; gravitational effect; autonomic regulation; cerebral autoregulation
MeSH headings : Autonomic Nervous System / physiology; Blood Circulation / physiology; Blood Pressure / physiology; Cerebrovascular Circulation / physiology; Homeostasis; Humans; Linear Models; Models, Cardiovascular; Posture / physiology
topics (OpenAlex): Traumatic Brain Injury and Neurovascular Disturbances; Optical Imaging and Spectroscopy Techniques; Cardiovascular Health and Disease Prevention
TL;DR: A mathematical model is presented that can predict dynamic changes in beat-to-beat arterial blood pressure and middle cerebral artery blood flow velocity during postural change from sitting to standing and is in agreement with physiological data from a young subject during postures change from Sitting to standing.
