WebThe flow of the network is defined as the flow from the source, or into the sink. For the situation above, the network flow is 19. Cuts A cut is a partition of vertices (V s, V t) such that the s V s and t V t. An edge that goes from u to v is a forward edge if u V s and v V t. If the opposite is true, then it is a backward edge. WebApr 12, 2024 · The optimal cut-off values for corrected flow time and ΔPPV6–8 were 356.5 ms and >1%, respectively. Conclusion: The change in PPV after tidal volume challenge and corrected flow time reliably predicted fluid responsiveness in patients undergoing robot-assisted laparoscopic gynecological surgery in the modified head-down lithotomy position.
