Table 1. APPS: a scoring system for ARDS patients.
Variables | 1 point | 2 points | 3 points | Score |
---|---|---|---|---|
Age, years | <47 | 47–66 | >66 | |
PaO2/FiO2, mmHg | >158 | 105–158 | <105 | |
Plateau pressure, cmH2O | <27 | 27–30 | >30 | |
Total score |
APPS (age, plateau, PaO2/FiO2) score: a 9-point outcome score for patients with the acute respiratory distress syndrome. The score is based on patient’s age, PaO2/FiO2, and plateau pressure at 24 hours after ARDS onset. PaO2/FiO2 is calculated under standardized ventilator settings [see reference (5) for details]. Total score is equal to the sum of the points for each category at 24 hours after ARDS diagnosis. Minimum total score is 3 points; maximum score is 9 points.
