Mean values (± S_D_) of the Cardiac Output (CO), Pulse Transit Time (PTT) and Initial Systolic Time Interval (ISTI) at three moments, before and after intravenous administration of a Gelofusine® solution in two steps of 250 ml each_
| moment | CO (L/min) | PTT (ms) | ISTI (ms) |
|---|---|---|---|
| before infusion | 4.7 ± 1.2 | 190 ± 9 | 148 ± 30 |
| after 250 ml | 4.9 ± 1.3 | 184 ± 10 | 151 ± 28 |
| after 500 ml | 4.9 ± 1.3 | 179 ± 9 | 151 ± 26 |
Relationships between the Initial Systolic Time Interval ISTI (ms) and the Cardiac Output CO (L/min) at the three moments before, after the first and after the second intravenous fluid administration of 250 ml (N = 16)_ The coefficients of correlation r and the levels of significance p are also given_ The last row gives the relationship for the pooled data (N = 48)__
| moment | relationship ISTI = | r | p |
|---|---|---|---|
| before infusion | -13.5·CO + 211 | 0.5453 | < 0.025 |
| after 250 ml | -10.1·CO + 201 | 0.4920 | < 0.05 |
| after 500 ml | -9.5·CO + 197 | 0.4609 | < 0.05 |
| pooled data | -10.7·CO + 202 | 0.4917 | < 0.005 |
