THE ADAPTATION OF THE LUNG CIRCULATION TO THE VENTILATION
In normal circumstances 55 per cent. of the total blood supply to the lungs of the rabbit is directed to the right and 45 per cent. to the left lung. On lowering the alveolar oxygen tension in one lung its blood circulation may be gradually reduced to less than half of the original value. while the...

Summary: | In normal circumstances 55 per cent. of the total blood supply to the lungs of the rabbit is directed to the right and 45
per cent. to the left lung. On lowering the alveolar oxygen tension in one lung its blood circulation may be gradually reduced
to less than half of the original value. while the circulation of the other lung shows a corresponding increase.
A drop in the alveolar oxygen percentage of 2 to 2·5 per cent. in one lung may reduce the blood-flow by 15 per cent. of the
original value.
The significance of these results with reference to an adaptation of the circulation to the unequal ventilation of the lungs
is discussed. |
