Effect of halothane on cardiac output and regional flow in the fetal lamb in utero.

abstract：BACKGROUND:Currently, the monitoring of cardiac output (CO) and stroke volume (SV) is mainly performed using invasive techniques. Therefore, performing CO monitoring noninvasively by means of electrical impedance tomography (EIT) would be advantageous for intensive care. Our hypothesis was that, by means of EIT, it is ...
