The APACHE II Score Calculator is a valuable tool used in the medical field to assess the severity of illness in critically ill patients. This calculator provides a numerical score based on various physiological parameters, aiding healthcare professionals in predicting patient outcomes and making informed decisions about their care.
Formula of APACHE II Score Calculator
The APACHE II Score is calculated using the following formula:code
APACHE II Score = (0.168 * Age) + (0.233 * GCS) + (0.96 * MAP) + (1.387 * Heart rate) + (1.305 * Respiratory rate) + (0.322 * Temperature) + (1.711 * FiO2) + (0.675 * pH) + (2.703 * Sodium) + (1.849 * Potassium) + (0.656 * Creatinine) + (0.117 * Hematocrit) + (0.618 * White blood cell count)
Where:
- Age: Age of the patient.
- GCS: Glasgow Coma Scale score (ranges from 3 to 15).
- MAP: Mean Arterial Pressure.
- Heart rate: Heart rate in beats per minute.
- Respiratory rate: Respiratory rate in breaths per minute.
- Temperature: Body temperature in Celsius.
- FiO2: Fraction of inspired oxygen as a decimal (e.g., 0.5 for 50%).
- pH: Arterial pH.
- Sodium: Serum sodium concentration in mmol/L.
- Potassium: Serum potassium concentration in mmol/L.
- Creatinine: Serum creatinine concentration in mg/dL.
- Hematocrit: Hematocrit percentage.
- White blood cell count: White blood cell count in cells/mm³.
General Terms Table
| Term | Description |
|---|---|
| MAP | Mean Arterial Pressure |

Example of APACHE II Score Calculator
Let’s consider a hypothetical scenario. A patient with an age of 45, a GCS score of 10, a MAP of 85 mmHg, a heart rate of 80 bpm, a respiratory rate of 18 breaths/min, a temperature of 38°C, FiO2 of 0.4, pH of 7.35, sodium level of 140 mmol/L, potassium level of 4 mmol/L, creatinine level of 1.2 mg/dL, hematocrit of 35%, and a white blood cell count of 10,000 cells/mm³.
By plugging these values into the APACHE II Score formula, we can calculate the patient’s APACHE II Score.
Most Common FAQs
A: The APACHE II Score is crucial in predicting the severity of illness in critically ill patients, aiding healthcare professionals in making informed decisions about patient care and resource allocation.
A: Generally, a higher APACHE II Score indicates a more severe illness and a potentially higher risk of mortality.
A: The frequency of calculation depends on the clinical scenario. In intensive care settings, it may be assessed regularly to monitor the patient’s progress.
