Result: PESI 50 - Class I (very low risk; 30-day mortality 0.0-1.6% per Aujesky 2005 Table 4).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- I (<=65)
- 30-day mortality 0.0-1.6% per Aujesky 2005 Table 4 (Class I).
- II (66-85)
- 30-day mortality 1.7-3.5% per Aujesky 2005 Table 4 (Class II).
- III (86-105)
- 30-day mortality 3.2-7.1% per Aujesky 2005 Table 4 (Class III).
- IV (106-125)
- 30-day mortality 4.0-11.4% per Aujesky 2005 Table 4 (Class IV).
- V (>125)
- 30-day mortality 10.0-24.5% per Aujesky 2005 Table 4 (Class V).
