ALGOR MORTIS PDF
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.

Determination of algor mortis changes alone is not sufficient in determining postmortem interval. Some of these formulas become less accurate at higher temperatures and significantly overestimate, and cold temperatures significantly underestimate the postmortem interval.
This variable is based on the assumption that body temperature was normal at the time of death and includes both temperatures above and below normal living body temperature, Eden 1 ; Brooke Thomas.

Development of faster formulas based on the level of decomposition, humidity, and temperature algor mortis would have a significant impact on investigations. Generally, temperature change is considered an inaccurate means of determining time of death, as the rate of change is affected by several key factors, including: Clear Turn Off Turn On.

Epub Aug PubMed Links to PubMed. Clinical Significance Determination of algor mortis changes alone is not sufficient in determining postmortem interval. 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.
