Effect of positive and negative expiratory pressure on renal function

Abstract

The effects of positive and negative and expiratory pressure on renal function have been studied in adult greyhounds with a normal blood volume and without evidence of cardiorespiratory disease. Positive expiratory pressure (+10 cm H2O) resulted in a decrease of urine volume, glomerular filtration rate and renal blood flow which returned towards normal following removal of the positive pressure. Negative expiratory pressure ( - 6 cm H2O) resulted in opposite changes in renal function. © 1977 Copyright: Macmillan Journals Ltd.
