THE USE OF THE ROLLING MANOMETER SYSTEM FOR MEASURING CORONARY BLOOD FLOW

[摘要] References(5)Cited-By(2)Previously a new type of flowmeter has been presented in this journal (1). The principle of this method is based on Poiseuille's formula indicating that the volume of blood flow is a function of the pressure difference between the two points of flowing tube. A rolling manometer system was devised to measure the above pressure difference. This method was tested, modified and confirmed that it is inexpensive, durable, sensitive and versatile (2).In the present study the blood flow through the coronary artery of the isolated perfused heart was measured continuously by using the rolling manometer. For perfusing the isolated heart a modified Heymans and Kochmann's method (3) was employed in which a donor animal supplied its own blood for perfusion.
