Simplified APACHE Score vs Heart Rate

Simplified APACHE II Score

The full APACHE II uses 12 physiologic variables, age, and chronic health status. This simplified version uses the most accessible variables.

Age Points

AgePoints <450 45-542 55-643 65-745 75+6

Score Interpretation

Higher scores indicate greater severity. The full APACHE II (0-71) correlates with ICU mortality risk. This simplified version provides a directional estimate.

Example Calculation

A 60-year-old ICU patient: temp 101F, HR 100, GCS 14.

  1. 01Age points = 3 (55-64)
  2. 02Temp = 38.3C, deviation = 1.3, points = 1
  3. 03HR deviation from 80 = 20, points = 0
  4. 04GCS points = 15 - 14 = 1
  5. 05Total = 3 + 1 + 0 + 1 = 5
