What is dependent lividity?
dependent lividity — A reddish-blue discoloration of the skin resulting from the gravitational pooling of blood in the blood vessels evident in the lower lying parts of the body in the position of death. Also called livor mortis.
What are four common post mortem indicators considered in an autopsy elaborate?
There are 4 stages: Pallor Mortis, Algor Mortis, Rigor Mortis and Livor Mortis. Death is one of the most fundamental facts of life. After we die, there are 4 stages of changes that occur in the body.

What is death lividity?
Livor mortis, also known as lividity or hypostasis, is the gravitational pooling of blood to lower dependant areas resulting in a red/purple coloration. Although livor mortis is commonly seen between 2 and 4 h postmortem, its onset may begin in the ‘early’ period, as little as 30 min postmortem.
What is cadaveric lividity?

How long does lividity stay fixed after death?
If the area does not blanch, lividity is fixed and the time since death is more than 8 hours. Fixation is due to the diffusion of haemoglobin through capillary walls and staining of the tissues, permanently.
