Abstract
Most researchers derived the arterial pressure-wave equation by taking the axial blood flow as the major mechanism and assumed the flow motion was governed by the Navier-Stokes equation. However, only realistic hemodynamic theory can help to develop method for future healthcare. Here, we pointed out a different rigorous hemodynamic model that explained many physiological facts. Our previous work started directly from Newton's law by deriving the radial and the axial momentum equations of the elastic arterial wall system and of the enclosed blood system, with the contact forces between the two systems being counted explicitly. Our model has some important applications in future healthcare, such as providing a basis for studying the collective behavior of the cardiovascular system and developing quantitative methods for disease prevention and diagnosis.
