Experimental study on the hemodynamics of the neonatal brain.

The effects of inhalation of different gases were studied in neonatal rabbits with the following results: In neonates with normal heart rate (HR), hyperoxia induced by O2 inhalation did not appreciably affect HR, but it increased cerebral tissue PO2, while decreasing cerebral blood flow (CBF). In many of those which fell into a state of marked bradycardia… CONTINUE READING
