Table 2 Baseline mean cardiac output and median carotid ultrasound parameters (corrected flow time and blood flow) pre- and post-passive leg raise
Parameter | Pre-passive leg raise median (interquartile range) | Post-passive leg raise median (interquartile range) | p value |
|---|---|---|---|
Mean cardiac output ± standard deviation (SD) (L/min) | 5.15 ± 1.58 | 5.19 ± 1.58 | 0.69 |
Corrected flow time (single waveform in milliseconds) | 331.7 (308.6–357.8) | 344.2 (321.6–360.6) | 0.06 |
Corrected flow time (average of three waveforms in milliseconds) | 335.2 (311.0–359.3) | 339.6 (322.1–368.9) | 0.13 |
Blood flow (single waveform in mL/min) | 576.3 (389.5–806.9) | 551.77 (441.5–763.5) | 0.45 |
Blood flow (average of three waveforms in mL/min) | 555.4 (422.1–766.6) | 558.3 (452.7–741.6) | 0.45 |
