METHOD FOR DETERMINING CEREBRAL BLOOD SUPPLY DISORDERS

摘要

medicine. SUBSTANCE: method involves recording differential rheograms taken from neck, chest, arm areas. Blood volume delivered to the head is calculated as difference between blood circulation volumes on the chest-neck area and chest-arm area. Enveloping rheogram is recorded on the chest-neck area. Its venous systolic and basic wave amplitudes are measured. Left atrioventricular heart orifice blood flow Doppler ultrasonogram is recorded. Mean blood flow rates are measured during the early right heart ventricle filling time period and right atrium systola filling time period. Their ratio is calculated. Head blood supply is determined from the calculated values. EFFECT: enhanced accuracy of the method.
