sci.APACHE-II-score-simplified Calculator
Calculates the APACHE II acute physiology score from 12 physiological variables plus age and chronic health points to predict ICU mortality risk. APACHE II score > 25 carries ~55% predicted ICU mortality — the score is calibrated on admission and is not intended for serial monitoring.
Inputs
Age Years
Age in completed years. Many health and fitness formulas adjust for age.
Gcs
Reference formula or conversion factor shown for context.
T C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Map Mmhg
Force per unit area (Pa). Atmospheric pressure at sea level: 101,325 Pa. Check whether gauge or absolute pressure is required.
Ph
Reference formula or conversion factor shown for context.
Creatinine Umol L
Reference formula or conversion factor shown for context.
Results
APACHE II score (partial)
A numerical rating from the scoring model in use.
age points
Sample size or count used in the calculation.
GCS points (15−GCS)
Sample size or count used in the calculation.
physiology points (T+MAP+pH+Cr)
MAP (mean arterial pressure) -- the average blood pressure over a full cardiac cycle. Normal: 70-100 mmHg. Below 65 mmHg in critically ill patients requires urgent intervention.
