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 [2] [3] 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.

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.
