Arteries are naturally elastic and able to respond to different and changing pressure conditions. If these changes could be characterized and quantified, this would be clinically useful. This study investigated arterial property changes with changes in arterial pressure using computer simulations and clinical measurements. Three elastic tube models (ideal elastic model, stretching elastic model and...
The characteristics of the arterial wall play an important role in cardiovascular physiology and pathophysiology. Arteries are normally elastic or compliant, allowing the artery diameter to expand under pressure. However, very little is known about this important property, as it is difficult to assess in vivo. This study examined this property indirectly from measurements of the time the pulse took...
Pressure is one of the most sensitive factors influencing the arterial wall compliance. Pulse transit time (PTT) is one simple way to assess arterial compliance changes. This study investigated the relationship between external cuff pressure and pulse transit time. The study was performed on 10 subjects with different cuff pressures (0, 10, 20 and 30 mmHg) on the lower arm, upper arm and whole arm...
