Doppler Sonographic Measurement of the Blood-Flow Rate in the Extracorporeal Tubing System During Arteriovenous Hemofiltration

Since Doppler ultrasound flow measurement was introduced to medicine [9] and was found to be practical for measuring flow rate [3], different modifications were quickly developed so that this method of transcutaneous arterial and venous measurement of blood flow could, in practice, be increasingly used in patients [11,12].
