Reliability of oscillometric central blood pressure and wave reflection readings: effects of posture and fasting.

Objective: Oscillometric pulse wave analysis devices have recently emerged, presenting suitable options for investigating central hemodynamic properties in clinical practice. This study sought to examine whether the between-day reliability of central SBP (cSBP) and systemic arterial wave reflection (augmentation index, AIx) readings exceed the criterion for acceptable reliability or are affected by posture (supine and seated) and fasting state.

Methods: Twenty healthy adults (50% female, 27.
