Medistim transit time flowmetry
WebCurrently transit-time flowmetry is used to assess graft patency on the basis of mean graft flow and derived values, such as the pulsatility index. ... (SPY) and TTFM (BF 2004; … WebTransit Time Flow Measurement. The TTFM principle is based on transmitting two ultrasound beams covering the blood vessel in both the upstream and downstream direction. The blood volume flow is then derived from the difference in propagation time of the upstream and downstream beams.

Web1 aug. 2024 · Transit time flowmetry is the most commonly applied technique of quality control in CABG surgery [6]. Whereas the value of the TTFM technique and graft patency at follow-up has been evaluated [6], the accuracy of the TTFM blood flow measurement has not been fully addressed in the clinical setting. WebThe Transonic flowmeter displayed a lower PI than the MediStim, due to a lower filter setting. In the Transonic,flow signals are filtered at a lower level, rendering a 'smoother' pattern of flow curves. Because different filter settings determine different PIs, caution must be taken when flow values …
