The Histogram of Local Oxygen Pressure (PO2) in the Dog Myocardium and the PO2 Behavior during Transitory Changes of Oxygen Administration
The purpose of this study was to get information concerning the supply of oxygen to the canine heart under steady-state conditions and concerning the dynamic behavior of the myocardial Po2 with sudden temporary changes of oxygen supply. Microelectrodes of trie size generally used for Po2 measurements in other organs proved to be too fragile for insertion into the beating heart. Therefore we had to employ electrodes with a tip diameter above 40/u.
