The cardiac output as well as minute volume of both ventricles during bilateral open chest under various positive pressures were determined by cardiometer in 12 rabbits. The output increased, in general, just after the change of pressure from 8cm. to 12cm and 16cm. of water positive pressures, but decreased 15 minutes later. When positive pressure changed from 4cm. to 8cm. of water the output decreased immediately after the pressure was changed, and still more 15 minutes later.
