For several years it has been shown the feasibility and clinical interest of non invasive aortic blood flow measurement in adult using an intraesophageal ultrasonic probe. In order to improve accuracy of this method a new flowmeter combining M-mode imaging system and pulsed Doppler was developped. The choice of such ultrasound techniques makes possible to measure simultaneously and continuously flow blood velocity and aortic diameter and allows more accurate aortic blood flow measurements as well in adult as in child patients (using a miniaturized oesophageal probe). In vivo experimental results show a 0.94 correlation coefficient between blood flow in descending aorta measured by this method and by means of electromagnetic flowmeter. |
