Abstract

The reservoir-wave paradigm separates pressure into windkessel-related 'reservoir' and wave-related 'excess' components, however the conceptual validity of this approach has not been sufficiently scrutinized. This paper assesses two logical implications of the reservoir-wave concept. First, parameters defining the reservoir (resistance and compliance) should be independent of wave effects. Second, wave analysis performed using excess pressure should provide a more accurate and physically intuitive representation of wave propagation and reflection in a vascular system, compared with the traditional wave analysis based on unseparated pressure. These issues were investigated with one-dimensiona..
