Your character better rush to the phone and call Emergency help. Now! Go! Because Mrs. Katt is still alive!
There are a few key stages after dead for a corpse. Your character may or may not know about these. Not many people have this in their Usage Memory, but you should at least understand the keywords and states.
- Livor mortis
- Hypostatic congestion
- Rigor Mortis
- post-mortem staining
- subcutaneous hypostasis
- cadaveric lividity
- darkening of death
Livor mortis is also called post-mortem staining, subcutaneous hypostasis, livor mortis, cadaveric lividity, suggillations, vibices and darkening of death. The intensity of the color depends upon the amount of reduced hemoglobin in the blood.
In cases of large amount of reduced hemoglobin before death, the blood has deep purplish-red color. It is caused by the stoppage of circulation, the stagnation of blood in blood vessels, and its tendency to sink by force of gravity. The blood tends to accumulate in the small vessels of the dependent parts. Filling of these vessels produces a bluish-purple color to the adjacent skin. The upper portions of the body drained of blood are pale. The color of the hypostasis may vary from area to area in the same body.
Hypostatic congestion resembling post-mortem hypostasis may be seen a few hours before death in case of a person dying slowly with circulatory failure, e.g. cholera, typhus, tuberculosis, uramia, morphine poisoning, congestive cardiac failure, and asphyxia. In such cases, hypostasis will be marked shortly after death. it is intense in asphyxia, where the blood may not readily coagulate, and in death from hemorrhages, anemia and wasting diseases due to reduced amount of blood and pigment. It is also less marked in death from lobar pneumonia, and other conditions in which the blood coagulates quickly.
The hypostatic areas have distinct color in certain cases of poisoning, e.g.
- In carbon monoxide poisoning, the colour is cherry-red.
- In hydrocyanic acid poisoning and sometimes in burns the colour is bright red.
- In poisoning by nitrites, potassium chlorinate, potassium bicarbonate, nitrobenzene and aniline [causing methaemoglobinaemia] the color is red-brown, or brown.
- In poisoning by phosphorus, the color is dark-brown.
In asphyxia, the colour of the stains is deeply bluish-violet or purple. In exposure to cold and refrigerated bodies the colour is pink, as the wet skin allows atmospheric oxygen to pass through, and also at low temperature haemoglobin has a greater affinity for oxygen. In septic abortion caused by Cl. Welchii the colour is often grayish-brown.
