Hemodynamic parameters by mode of ventilation
| Hemodynamic variable | VC | PC | PCV-VG |
|---|---|---|---|
| Heart rate (beats/minute) | 77 ± 10 | 73 ± 11 | 71 ± 11 |
| Systolic blood pressure (mmHg) | 99 ± 10 | 98 ± 11 | 96 ± 16 |
| Diastolic blood pressure (mmHg) | 62 ± 8 | 60 ± 11 | 59 ± 11 |
| Mean arterial pressure (mmHg) | 74 ± 8 | 72 ± 10 | 70 ± 11 |
VC = volume-controlled; PC = pressure-controlled; PCV-VG = pressure-controlled ventilation, volume guaranteed. The data are listed as the mean ± SD. For the hemodynamic variables, the value at each 5 minute interval was averaged to provide a single data point for each patient. P = NS for all variables and each mode of ventilation.
