From: Correlation of carotid corrected flow time and respirophasic variation in blood flow peak velocity with stroke volume variation in elderly patients under general anaesthesia

  Responders Nonresponders
T1 T2 T1 T2
SVV (%) 14.7(13–21) 9.1(4–13) a 10.5(6–14) b 6.5(2–11) ab
FTc (ms) 332.6 ± 9.9 356.4 ± 8.8a 344.2 ± 10.4b 363.6 ± 8.2ab
ΔVpeak (%) 13.1 ± 2.2 8.9 ± 1.5a 10.8 ± 2.2b 7.2 ± 1.8ab
  1. Data are presented as the mean (standard deviation) or median (interquartile range)
  2. a P < 0.05 vs. T1
  3. b P < 0.05 vs. responders
  4. T1 5 min after tracheal intubation,T2 5 min after completion of the fluid challenge, SVV stroke volume variation
