Abstract
A study was conducted on 26 healthy adults comparing the stroke volume (SV) and cardiac output (CO) measured with green dye and impedance cardiography in supine and sitting conditions and during 50-W bicycle exercise. The impedance pickup electrodes were modified from the standard band location and placed at the suprasternal notch and 10 cm lower. The percentage change of SV going from supine to sitting was -27.2 ± 7.4% and -16.9 ± 22% for the dye and impedance values respectively. The percentage change of SV going from sitting to exercise was 20.9 ± 11.9% and 36.7 ± 32.9% for the dye and impedance values, respectively. The percentage change in stroke volume determined by impedance shows poor agreement with dye values and considerably more variation.
