METHOD FOR DETERMINING PERFUSION PRESSURE IN AN EYE

摘要

medicine. SUBSTANCE: method involves determining cardiac index and specific peripheral blood vessel resistance using thoracic tetrapolar rheography method. Hematocrit values are determined and K coefficient value is calculated as ratio of cardiac index and product of specific peripheral blood vessel resistance and hematocrit value multiplied by one hundred. Perfusion pressure in an eye is determined from formula. Pperf = (Pophth mean - P0) x K, where Pperf is the perfusion pressure value, Pophth mean is the ophthalmic mean arterial blood pressure, P0 is the real intraocular pressure, K is the correction coefficient. EFFECT: high quality and accuracy of perfusion pressure measurement. 2 tbl
