Temperature < 35°C or 40°C or more+15
Pulse 125 beats per minute or more+10
Laboratory findingspH < 7.35+30
BUN > 10.7 mmol/L+20
Sodium less than 130 /L+20
Glucose > 13.9 mmol/L+10

Pleural effusion+10

*A risk score (total point score) for a given patient is obtained by summing the patient age in years (age minus 10 for females) and the points for each applicable patient characteristic.

⊃1;Oxygen saturation < 90 percent was considered abnormal in the Pneumonia PORT cohort study. The application of the PSI to the initial site of treatment decision (translational research) combines the PSI risk score and in addition considers the status of arterial oxygenation when used to guide the initial site of treatment.
