SIMULASI SISTEM MEKANIS KARDIOVASKULER MODEL HSP BERDASARKAN TEKANAN-VOLUME KONDISI ISTIRAHAT

Abstract

Non-invasive measurement is being a popular method in biomedical field at present time. Using this method an observation can be conducted without causing pain trauma of the patient. Using this instrument the data physiological condition of patient associated with cardiovascular disease can be provided. The purpose of this research is to characterize the mechanical characteristics of human’s cardiovascular system. The results will be issued in the form of pressure waves and volume at rest condition. Furthermore, the results of the simulation will be implemented on the physiological conditions of cardiovascular disease, which is coronary heart disease. The simulation was conducted using lumped parameters model HSP (heart-systemic-pulmonary) using Matlab R2008b. The simulation results showed in the resting state the left ventricular pressure is 120 mmHg and the right ventricular pressure is of 35 mmHg. Meanwhile, the left ventricular volume is 150 ml. the implementation for coronary heart disease by applying small amount of variation of resistance arteries coronary (KRlv), can be modeled. Comparing to the available references the patient simulation showed satisfactory results. This shows that the present method is adequate to simulate physiological conditions of human blood circulation. The simulation results show specific by references, either to arresting state as well as the results of the implementation of coronary heart disease. This shows that the simulation equality and already reflect the physiological conditions of human blood circulation. The differences resulting from differences in the results graph parameters and the used assumptions.
