Hemodynamic parameters at baseline and during maximal end-inspiratory apnea
| Baseline | Apnea | |
|---|---|---|
| MAP, mmHg | 86 ± 8 | 97 ± 16† |
| SBP, mmHg | 120 ± 13 | 134 ± 25* |
| DBP, mmHg | 69 ± 8 | 78 ± 15† |
| HR, beats/min | 55 ± 4 | 62 ± 6† |
| SV, ml | 86 ± 12 | 81 ± 11* |
| CO, l/min | 4.7 ± 0.6 | 5.0 ± 0.7 |
| TPR, mmHg·l−1·min−1 | 19 ± 2 | 21 ± 3* |
| PetO2, Torr | 103 ± 3 | 56 ± 3† |
| PetCO2, Torr | 39 ± 3 | 56 ± 4† |
Values are means ± SD. MAP, mean arterial pressure; SBP, systolic blood pressure; DBP, diastolic blood pressure; HR, heart rate; SV, stroke volume; CO, cardiac output; TPR, total peripheral resistance; PetO2, end-tidal partial pressure of O2; PetCO2, end-tidal partial pressure of CO2.
