Abstract: The Pulse Transit Time (PTT) is the time it takes for a pulse wave to travel from proximal to distal measurement points. The electrocardiogram/pulse plethysmogram is often used as a proximal/distal pulse wave. The PTT is an indicator of blood vessel stiffness. The blood vessel wall tension increases with increasing blood pressure. As a result, the pulse wave moves faster and the PTT decreases. The aim of this thesis is to investigate to what extent the circulatory function of a patient can be monitored during dialysis using the PTT with regard to problematic blood pressure drops.
