What does APACHE mean in PHYSIOLOGY
APACHE stands for Acute Physiology Age and Chronic Health Evaluation. It is a scoring system used to assess the severity of illness in critically ill patients. It was developed in 1981 by William Knaus and colleagues at the George Washington University Medical Center in Washington, D.C. It is used to predict mortality and length of stay in the intensive care unit (ICU).
APACHE meaning in Physiology in Medical
APACHE mostly used in an acronym Physiology in Category Medical that means Acute Physiology Age and Chronic Health Evaluation
Shorthand: APACHE,
Full Form: Acute Physiology Age and Chronic Health Evaluation

Components
The APACHE score is based on a number of factors, including:
- Physiological variables: These include vital signs, laboratory values, and other measures of organ function.
- Age: Patients who are older are at higher risk of death.
- Chronic health conditions: Patients with chronic health conditions are also at higher risk of death.
Calculation
The APACHE score is calculated by summing the points for each of the following factors:
- Temperature: 0-4 points
- Heart rate: 0-4 points
- Respiratory rate: 0-4 points
- Blood pressure: 0-4 points
- Glasgow Coma Scale: 0-4 points
- Serum sodium: 0-4 points
- Serum potassium: 0-4 points
- Serum creatinine: 0-4 points
- White blood cell count: 0-4 points
- Arterial pH: 0-4 points
- Age: 0-4 points
- Chronic health conditions: 0-4 points
Interpretation
The APACHE score ranges from 0 to 40. A higher score indicates a higher risk of death. The following table shows the risk of death associated with different APACHE scores:
| APACHE Score | Risk of Death |
|---|---|
| 0-10 | <1% |
| 11-20 | 1-5% |
| 21-30 | 5-10% |
| 31-40 | >10% |
Essential Questions and Answers on Acute Physiology Age and Chronic Health Evaluation in "MEDICAL»PHYSIOLOGY"
What is APACHE?
APACHE (Acute Physiology Age and Chronic Health Evaluation) is a scoring system used to assess the severity of illness in critically ill patients. It is based on the patient's physiological parameters, age, and chronic health conditions.
How is APACHE calculated?
APACHE is calculated using a formula that includes 34 variables, including vital signs, laboratory values, and chronic health conditions. Each variable is assigned a score based on its severity. The total score is used to classify the patient's illness severity.
What are the different APACHE scores?
There are several different APACHE scores, including APACHE II, APACHE III, and APACHE IV. Each score is designed for a specific population of critically ill patients. APACHE II is the most commonly used version.
What is the purpose of APACHE?
APACHE is used to predict the risk of death in critically ill patients. It can also be used to compare the severity of illness between different patients and to track changes in illness severity over time.
How accurate is APACHE?
APACHE is a reasonably accurate predictor of mortality in critically ill patients. However, it is important to note that it is only a prediction and should not be used as the sole basis for making treatment decisions.
What are the limitations of APACHE?
APACHE is limited by the accuracy of the data that is used to calculate the score. It is also important to note that APACHE does not take into account all of the factors that can affect a patient's prognosis.
Final Words: The APACHE score is a valuable tool for assessing the severity of illness in critically ill patients. It can be used to predict mortality and length of stay in the ICU. However, it is important to note that the APACHE score is not a perfect predictor of outcome. Other factors, such as the patient's overall health status and the quality of care they receive, can also affect their outcome.
