Comparison between the three methods restricted to the very stable period
| Maximum | Minimum | Mean | SD | |
| CO values | ||||
| PAC-CCO | 8.7 | 2.5 | 4.8 | 1.4 |
| NICOM™ | 10.2 | 2.1 | 4.8 | 1.4 |
| FloTrac-Vigileo™ | 11.2 | 1.0 | 5.0* | 1.2 |
| Differences in CO | ||||
| Vigileo™ – PAC-CCO | 4.8 | -3.0 | 0.1 | 0.9 |
| NICOM™ – PAC-CCO | 5.3 | -2.7 | 0.0† | 1.0 |
| NICOM™ – Vigileo™ | 4.1 | -5.1 | -0.1 | 1.2 |
| Relative errors | ||||
| Vigileo™ | 0.97 | 0.0 | 0.16 | 0.12 |
| NICOM™ | 1.15 | 0.0 | 0.17† | 0.12 |
Relative error = (tested CO – PAC-CCO)/PAC-CCO.
* P < 0.05 vs. PAC-CCO, † P < 0.05 for NICOM™ vs. Vigileo™
CO = cardiac output; SD = standard deviation.
