Table 2 Comparison of the number of cases with blood flow velocity waveform changes in peripheral arteries in each group.
| Group | CA–WF+/WF− | BA–WF+/WF− | FA–WF+/WF− |
|---|---|---|---|
| FR+ Group | 18/12 | 9/21 | 8/22 |
| FR− Group | 4/26 | 2/28 | 5/25 |
| χ | 13.833 | 5.364 | 0.869 |
| p | >0.05 | ||
| FR+ Group indicates fluid responsive group. FR− Group indicates fluid non-responsive group. WF+ indicates patients with significant periodic inspiratory waveforms and expiratory waveform changes. WF− indicates patients with no periodic waveform changes or no significant changes. CA indicates carotid artery. BA indicates brachial artery. FA indicates femoral artery. | |||
