Pressure indicated by the injector gauge needle when the arterial tube is open and the arterial fluid is flowing into the body
Actual pressure
Pressure exerted by the blood vessel walls measured in millimeters of mercury
Blood pressure
Difference between potential and actual pressures
Differential pressure
Pressure indicated by the injector gauge needles when the injector motor is running and the arterial tubing is clamped off
Potential pressure
Amount of pressure produced by an injection device to overcome initial resistance within or on the vascular system
Injection pressure
The force required to distribute an embalming fluid solution throughout the body
Pressure
Passage of embalming solution through the capillary wall to diffuse with the interstitial fluids by application of positive intravascular pressure
Pressure filtration
Hot water embalming
Should only be used in desperation, cold water embalming should be the norm
Pressure which will overcome vascular resistance and cause a moderate, uniform movement of arterial solution from the injector into the vascular system and ultimately into the tissue cells
Ideal injection pressure
Feature swelling and distortion is also known as
Water logging
Type of chemical that reduces surface tension
Surfactant
Less surface tension = better distribution and diffuse
Fluid dye
Distension of superficial blood vessels
Blood drainage
Clearing of intravascular blood discolorations
Signs of arterial solution distribution
Dye in the tissues
Firming of the tissues
Loss of skin elasticity (begin firming)
Drying of the tissues
Rounding of the fingertips, lips, and toes
Mottling of the tissues (bleaching)
Florescent dye observed using “black light”
Signs of arterial solution diffusion
Fastest we can embalm 1 gallon of fluid into a body
15 minutes
Flow meter measures the rate of flow in
Ounces per minute
Capacity of blood vessels
Arteries 5%
Veins 10%
Capillaries 85%
The highest pressure is always at
The point of injection
Small solutes
Crystalloids
Large solutes
Colloids
Active due for cosmetic purposes must be injected from the
Femoral artery
It is not so much the volume of solution injected into the body that counts, but the amount that actually remains there.
Arterial fluid retention
Hot water
High index 30+
Waterless (used in head freeze)
Often used in combination with each other
Instant tissue fixation
Multipoint injection on an Unautopsied body
Both carotids
Both axillaries
Both femorals
With corresponding veins
Multipoint injection on an autopsied body
Both subclavians
Both external illiacs
Both carotids
