FFRmyo = Pd Pa (at maximum hyperemia) 1)
1. Advance sensor element distal to the stenosis of interest. 2. Wait for stable baseline pressure values. 3. Use cathlab standard routines to induce maximum hyperemia. 4. Press REC to start recording. 5. When maximum hyperemia is reached, press STOP/VIEW to stop recording. (The instrument then calculates FFR automatically.)
Move cursor with LEFT and RIGHT buttons. Press ENTER so save new position and leave menu. Press ESC to leave without saving position.
AFTER PROCEDURE – VERIFY EQUAL AO AND PRESSUREWIRE® PRESSURES 1. Withdraw PressureWire® so that the pressure element is just outside the guiding catheter opening. 2. Verify that AO (Pa) and PressureWire® (Pd) pressures are equal (difference < 5 mmHg) at that position.
