Algor mortis is one of three stages a body goes through after death that helps medical examiners determine time of death. This lesson. After the death of a person, the body undergoes certain changes in an orderly manner, namely pallor mortis, algor mortis, rigor mortis and livor mortis. Algor mortis cools down at In human, it usually appear in 2 hours after the death . The stiffness will begin from smaller muscles to larger.

Algor mortis – Wikipedia
As decomposition occurs the internal body temperature tends to rise again. This is especially important in medicolegal and forensic death investigations. National Center for Biotechnology InformationU. This is generally a steady decline, although if the ambient temperature is above the body temperature such as in a hot desertthe change in temperature will be positive, as the relatively cooler body acclimates to the warmer environment. The Glaister equation   estimates the hours elapsed since death as a linear function of the rectal temperature:.
There are complex algorithms that take many variables to determine postmortem interval. However, numerous variables affect the rate and direction of algor mortis and complicate alyor use in estimating time of death.
Some of these formulas become less accurate at higher temperatures and significantly overestimate, and cold mrtis significantly underestimate the postmortem interval. Forensic Medicine 2nd ed. Epub Mar 4. StatPearls Publishing; Jan.
The term was first used by Dowler in Signs of death Latin medical phrases Forensic pathology Medical sign stubs Death stubs Latin words and phrases stubs.
Generally, temperature change is aglor an inaccurate means of determining time of death, as the rate of change is affected by several key factors, including: Clinical Significance Determination of algor mortis changes alone is not sufficient in determining postmortem interval.

Rectal temperatures are commonly used as the standard to determine the decedent temperature and algor mortis. This page was last edited on 11 Mayat This book is distributed under the terms of the Creative Commons Attribution 4.
From Wikipedia, the free encyclopedia. Although the heat conduction which leads to body cooling follows an exponential decay curve, it can be approximated as a linear process: External factors can have a significant influence.
