Abstract
Hemodynamic parameters play a very important role in supporting physicians to diagnose and treat cardiovascular diseases. This paper presents the results of the study on designing of noninvasive hemodynamic monitoring equipment using impedance cardiography (ICG). This is a measurement method that shows many advantages and is interested in the present. The equipment has ability of measurement and monitoring hemodynamic parameters include: heart rate HR; thoracic fluid content TFC; left ventricular ejection time LVET; stroke volume SV; cardiac output CO and ICG waveform. Results of measurement between the research equipment BK-NICO and the standard equipment of NICCOMO for 104 patients show that the hemodynamic parameters measured by the two equipments are quite small difference. Specifically, the average deviation of the parameters obtained, HR is 0.16 bpm, TFC is 0.73 1/kΩ, LVET is 5.95 ms, SV is 0.17 ml, CO is 0.01 lpm. With the results of the research, the device is fully capable of deploying the application into practice in the hospitals to replace the current invasive measurement method.
