RESUSCITATION of the heart in patients with cardiac arrest or ventricular fibrillation is usually accomplished with cardiac massage. This restores circulation in both the pulmonary and the systemic circuits, but tit times it seems to be inadequate because the blood pressure and the pulse cannot be adequately maintained. A further disadvantage is that a surgical procedure cannot be performed on ...

The present study was undertaken to determine whether a biventricular bypass system operated in an independent variable rate (VR) mode can maintain the entire circulation. Two pusher-plate pumps which incorporated the Hall effect position sensors were used to bypass the right and left ventricles in 10 sheep under fibrillation. The flow distributions of the pump output to the carotid and renal a...

The degradation in efficiency of auxiliary components in heating/cooling systems when operating at part load is frequently reported. Through the use of variable speed components, the supplied capacity can be reduced to match the required load and hence reduce unnecessary energy consumption. However, for fan coil units, difficulties can arise when optimizing fan and pump speeds at part load. Pra...

conclusions intraperitoneal migration of a subfascially placed baclofen pump is a rare, yet serious complication, which has been reported only once in the literature. we advise neurosurgeons to have a low level of threshold in confirming the location of a baclofen pump with imaging and surgical exploration if necessary in order to avoid detrimental outcomes such as bowel perforation. case prese...
