Abstract

Bu çalışmada, fizyoloji alanında karmaşık bir sistem
olarak kabul edilen insan kardiyovasküler sistemin sahip olduğu mekanizmaların
ve dinamiklerinin anlaşılabilmesine fayda sağlayacak elektriksel bir devre
modeli önerilmektedir. Windkessel model olarak tanımlanan elektriksel devre
modeli, kalpten pompalanan kan basıncının arteriyel sistemdeki karakteristik
etkisinin gözlemlenmesinde önemli rol oynamaktadır. Windkessel modelin girişine
entegre ettiğimiz ayrı bir elektrik devre modeli, ortalama arteriyel kan
basıncı sinyallerinin beklenen değer aralıklarında gözlemlenmesini
sağlamaktadır. Bu çalışmada ele alınan ve geliştirmeye çalıştığımız Windkessel
devre modeli laboratuvar ortamında kurulumu gerçekleştirilmiş ve sonuçları
gözlemlenmiştir. Kalp ve arteriyel sistem ilişkisinde rol alan parametre
sayılarının arttırılarak, Windkessel modelin geliştirilmesine bir alt yapı
olması açısından bu çalışmanın literatüre katkı sağlayacağı düşünülmektedir.

Electrical Analogue of Arterial Blood Pressure Signals

Abstract

In this study, we propose
an electrical circuit model that will be useful for understanding of the
mechanisms and dynamics of the human cardiovascular system, which is considered as a complex system in the field of physiology. The
electrical circuit model, defined as the Windkessel model, plays an important
role in the observation of the characteristic effect of the blood pressure on
the arterial system. An electrical circuit model, which we have connected to
the input terminals of the Windkessel model, ensures that the mean arterial
blood pressure signals are observed within the expected range of values. The
Windkessel circuit model that we have tried to develop in this study was
constructed in a laboratory environment and the results were observed. It is
thought that this study will contribute to the literature in terms of the
development of the Windkessel model by increasing the number of parameters
involved in the models of heart and arterial system.
