摘要：
The present invention provides a system for determining blood flow rate in a vessel which communicates blood between two locations of a patient, the system comprising: a conduit in fluid communication with the vessel; at least one sensor in communication with the vessel for determining differential blood pressure (? P) between two or more locations within the vessel; and a processor operably connected to the at least one sensor for processing the ? P to obtain blood flow rate within the vessel.A method for determining blood flow rate in a vessel which communicates blood between two locations of a patient, the method comprising: diverting blood from the vessel at a diversion point to obtain a flow of diverted blood in a conduit; determining differential blood pressure (? P) of the diverted blood through the conduit; and processing the ? P to obtain blood flow rate within the vessel.
