Methods Extracorporeal circulation was carried out in nine adult mongrel dogs using a
Crafoord-Senning pump-oxygenator. Through a right thoracotomy a single cannula was …

Methods Thc Crafoord-Senning pump-oxygenator, described in detail elsewhere," was used
in these experiments. The blood is oxygen-ated on a series of perforated cylindrical rollers …

WITH the increased use of pump-oxygenators, attention has been focused upon the
physiologic and biochemical changes during extracorporeal circulation. Certain …

kilograms, were anes thetized with intravenous Nembutol, intubated intratracheally, and …

Methods Forty-nine mongrel dogs were perfused for 30 minutes utilizing the operative
technics and pump-oxygenator developed by Lillehei and associates.** Dogs were …

In anesthetized dogs a fraction of the venous blood flow was diverted into a heart-lung
machine (gas exchange bag) and from there infused by gravity into the arterial circulation …
