摘要: A non-invasive aortic blood flow sensor is disclosed. The determines the in aorta of a patient based on pressure difference between right and left subclavian arteries. arteries non-invasively measured by determining pressures patient's arms means tonometric sensors. signals from sensors are first equalized to account for any waveform distortion due propagation pulse locations. Next, correction made DC offset. modified then compared, determined. determined known pressure/flow relationships.
