Table 1 Carotid and coronary blood flow average peak velocities during different ECMO regimens.

From: Coronary versus carotid blood flow and coronary perfusion pressure in a pig model of prolonged cardiac arrest treated by different modes of venoarterial ECMO and intraaortic balloon counterpulsation

N = 11 Baseline Cardiac arrest FS FS+IABP FF FF+IABP
Flow Velocity (cm/s)       
Carotid 36.7 (33.3, 46.8) 12.0 (7.0, 12.0) 32.0 (25.5, 43.5) 32.3 (27.3, 39.0) 35.0 (25.7, 48.0) 27.3 (24.7, 37.3)
Coronary 21.7 (19.3, 24.4) 8.0 (7.0, 9.8) 14.0 (10.3, 25.0) 17.0 (15.9, 23.0) 18.7 (16.4, 21.8) 15.7 (11.5, 18.8)
Flow Velocity
(% of baseline)
      
Carotid --- 23.8 (20.5, 34.6) 101.5 (65.6, 108.6) 98.0 (76.4, 120.9) 90.3 (79.4, 129.1) 81.8 (64.7, 124.3)
Coronary --- 32.6 (29.6, 42.3) 70.0 (49.1, 113.2) 76.7 (71.9, 111.2) 90.0 (66.1, 98.6) 60.7 (55.1, 86.2)
  1. Assessment performed by Doppler flow wire measurements in cm/s (upper part) and as a percentage of baseline (bottom part). FS, femoro-subclavian; FF, femoro-femoral; IABP, intraaortic balloon counterpulsation; The median of baseline percentage is not percent expression of absolute value median. It is a median of baseline percentage from each experiment.
