Table 1 Intra-abdominal pressure findings in prone ventilation studies involving animals
Study | Animals | Intervention | Abdomen unloading? | Mean supine IAP (mmHg) | Mean prone IAP (mmHg) | Comments |
|---|---|---|---|---|---|---|
Mure and colleagues [34] | 8 pigs | Intra-abdominal | No | 7 (no distension) | 8 (no distension) | Gas exchange most improved when abdomen distended |
| Â | Â | Balloon inflation | Â | 24 (distension) | 18 (distension) | Â |
Colmenero-Ruiz and colleagues [35] | 20 pigs | Oleic acid induced | Randomized | 3.7 (no suspension) | 6.5 (no suspension) | No gas exchange benefits from suspension |
| Â | Â | Acute lung injury | Â | 3.4 (suspension) | 7.2 (suspension) | Â |
