[Gas exchange and gas transport in deeply cooled rats during slow and rapid warming using artificial pulmonary
Abstract:
Artificial lung ventilation (ALV) was shown to restore the gas exchange in rats following their cooling to brain temperature 17.0-17.6 degrees C. However, the ALV proved ineffective if applied in 22.1 +/- 2.1 min after cessation of breathing. Fast warming up of the animals increased oxygen consumption and carbon dioxide production, and caused a less obvious metabolic acidosis in the rats in the course of recovering from hypothermia.
