Oxygen consumption of the frog's heart

Oxygen Consumption of Adrenalectomized and Renal Damaged Frogs

Oxygen Consumption of the Completely Isolated Dog Heart In Fibrillation

ELECTRIC induction of A'entricular fibrillation during cardiac surgery has been proposed recently, as a means of providing a quiescent organ and of diminishing the danger of air embolism. However before this procedure is adopted for routine clinical use, more should be known about its safety. Since myocardial damage may result when metabolic requirements are not met by the available oxygen, kno...

Quantitative determination of regional oxygen consumption in the dog heart.

A micro-Fick method has been developed to measure the O2 consumption of different regions of an organ. The method was tested in isolated dog gracilis muscle and consisted of microspectrophotometric determination of arterial and venous O2 saturation in quick frozen tissue to determine O2 extraction and flow measured with 85Sr-labeled microspheres, with O2 consumption calculated from the product....

Oxygen consumption in children with congenital diseases of the heart.

1. An open-circuit method for the measurement of oxygen consumption in children which is suitable for use during cardiac catheterization has been described. 2. Since it has been ppeviously shown that there is no systematic error in this method, the accuracy of the method is described by the random error (i.e. reproducibility). The reproducibility of the method has been determined by the repeate...
