Comparison of acetylene rebreathing and thermodilution methods for determining cardiac output

The usefulness of the acetylene rebreathing method in the noninvasive determination of cardiac output was compared with that of the thermodilution method. Simultaneous measurements of cardiac output by the acetylene rebreathing method and the thermodilution method were performed at rest in 20 patients with cardiac disease or hypertension and additionally during ergometer exercise in the supine position in 9 of 20 cases

Diagnosis of superior vena cava syndrome using pulsed Doppler echocardiography

The purpose of this study is to extract the signs of obstruction of the superior vena cava from the blood flow patterns and to assess the usefulness of pulsed Doppler echocardiography in the diagnosis of the superior vena cava syndrome
