Must know Notes Flashcards
- Fluid dye
- Distension of superficial vessels
- Blood drainage
- Leakage from intravenous punctures
- Clearing of intravascular blood discolorations
Signs of Distribution
- Dye in tissues
- Firming of tissues
- Loss of elasticity (begin firming)
- Drying of tissues
- Tissue distension- rounding of fingertips, lips and toes
- Mottling of tissues (bleaching)
- Fluorescent dye observed using black light
Signs of Diffusion
Potential of Hydrogen
pH
pH of 7.0
Neutral
pH of 6.9
As the number increases, the level of this decreases.
Acidic
pH of 7.1- 14
As the number increases the level of this increases.
Base (Alkaline)
Upon death, the pH starts to decrease. Eventually going to 7.0 (neutral). This stage is known as ______. The body is very limber.
1st Stage of Flaccidity (Primary Flaccidity)
Once at 7.0, the pH continues to move towards acidity stopping somewhere around 6.5-5.5. Eventually the pH will start to rise returning to 7.0 (netural). This stage is known as ________, the body will be at various stages of stiffness.
Stage of Rigor
Once at 7.0, the pH will continue to rise into the Base/Alkalinity range, increasing as time goes on. This is the stage of _______, when the body becomes limber again.
Secondary Flaccidity
Upon the pH raising to ____, the bacterial begins to thrive. Thus, the stage of decomposition begins to hasten.
8.0
The time frame that pH changes from 7.4 to acidic levels varies immensely for example, the stage of primary flaccidity am be as brief as a few seconds. This will be known as ______________.
- Occurs when death occurs suddenly and in situations such as stress.
Instantaneous Rigor Mortis
Reliving the rigor mortis of instantaneous rigor mortis is difficult to say the least. However it must be done at this time. Otherwise, it is almost impossible to properly position the hands.
Prior to Embalming
- Rotate
- Flex
- Extend
- Massaging
4 Ways to Relieve Rigor Mortis
States that rigor will first appear in the face, neck, thoaracic and abdominal cavities and will dissipate in the same order.
Nysten’s Law
People with _____ muscle will go into rigor faster, stay in the stage of rigor for a shorter time, be significantly less prominent during the stage of rigor, and enter the 2nd stage of flaccidity quicker.
Less
