Respiratory insufficiency as the inclusion criterion (Murray score [21] and European American Consensus Conference 1994 values)
| Murray Score (mean values of 40 patients) | ||
| Measured value | Points | |
| PaO2/FiO2 | 160 ± 15 | 3 |
| PEEP (mbar) | 10 ± 2 | 2 |
| Compliance (ml/cmH2O) |
36 ± 3 | 3 |
| X-ray quadrants | 2 ± 1 | 2 |
| Sum total | 10 | |
| Score (Sum total/4) | 2.5 | |
| European American Consensus Conference 1994 | ||
| ARDS: | ||
| acute onset | ||
| PaO2/FiO < 200 mmHg (peep independent) | ||
| Bilateral infiltration on ap chest X-ray | ||
| PCWP < 18 mmHg or absence of left atrial hypertension | ||
| ALI: | ||
| acute onset | ||
| PaO2/FiO2 < 300 mmHg (peep independent) | ||

PaO2, partial pressure of oxygen; FiO2, fractional inspiratory oxygen Concentration; PEEP, positive end-expiratory pressure; ARDS, acute respiratory distress syndrome; ALI, acute lung insufficiancy; ap, anterior-posterior; PCWP, pulmonary capillary wedge pressure.
