This product is known for its ability to work across a broader spectrum, it is less harmful than formaldehyde, and gives the embalmer less chance of tissues turning "putty gray"
H20 & alcohol are added to HCHO so that it will not...
dehydrate, disinfect, reduce chance of tissues turning grey/black
3 functions / reasons alcohol are added to HCHO
refers to only the amount of formaldehyde gas present.
the percent of hcho gas dissolved in an aqueous solution at room temperature.
40% 37%
2 different percentages used to measure index
20 grams
if an emb fluid contains a 20 index product, how many grams of formaldehyde gas per 100 mL of concentrated fluid is there?
37% gaseous HCHO + h20 + Alcohol =
HCHO + H20 + 2 Methyl Alcohols =
Hypotonic solution
What type of embalming fluid is typically used? (hypo/hyper)
hypertonic solution
what type of embalming fluid would be optimal for an edematous dcsd?
facilitates the process of osmosis
why do we use a hypotonic solution?
diffusion occurs
In embalming, preservation of the body (tissues) comes about when ( blank! ) occurs
capillary walls
the body is not considered fully embalmed until fluid passes through ...
delivery, distribution, drainage, diffusion
The 4 D's of embalming
shell embalming , short circuiting
when the embalmer arterially injects the body, the fluid takes the path of least resistance. If there is already fluid in the interstitial space/areas, and the arterial solution just merely "passes through" the vascular system, what is this referred to?
How much gaseous HCHO is in formalin?
This (main) embalming chemical changes a protein from a state in which it is easily decompose to a state where it will endure and not undergo putrefaction.
This chemical in embalming fluid allows for disinfection of the body tissues. It can also be used as surface disinfectant for the nasal cav, oral cav, and surface of body
Quartnery Ammonium Compound
This disinfecting agent cannot be used in arterial fluids, however it can be used in cavity fluids (also used for cold sterilization of instruments)
Modifying Agents
Buffers, humectants, and inorganic salts make up...
These modifying agents control the acid/base (pH) balance of embalming chemicals
These modifying agents increase the capability of embalmed tissue to retain moisture, as well as controlling and delaying the firming / and or drying action of preservatives.
Inorganic Salts
These modifying agents serve a variety of purposes, most notably controlling or determining the osmotic qualities of the embalming soln. They can also help to draw out fluid from the cappillaries, or even draw fluid to capps for drainage purposes.
Chemical found in embalming fluid which is used to keep the blood in a liquid state.
water softeners
Additives, supplemental chemicals used to improving drainage by softening up clotted material. They also work to reduce the hardness of water, which enhances the function of arterial fluid in body
which component of embalming fluid would be imperative in treating remains with illness such as pneumonia or febrile diseases?
which component of embalming fluid functions to control & delay firming and or drying action of preservatives?
Which component of embalming fluid acts as tension breakers, or tension reducers by reducing molecular cohesion of a liquid and enable it to flow through smaller openings?
which component of embalming fluid is used to promote diffusion of preservative substances through cappillary walls to saturate tissues evenly?
Capillary Attraction
The force that attracts & holds liquid in the capillary tube, also known as the result of surface tension
which components of embalming solution diffuse superficial tissue areas from the circulation system, and are available with active, or inactive abilities?
perfuming agents
which component of embalming fluid acts as a masking agent by releasing fumes when they come into contact with tissue?
what component of embalming fluid acts is considered a solvent, or mixture of solvents which keeps the subtances active and in a stable & uniform state during transport through the circulation system to all parts of the body?
vascular fluid
any fluid injected into the vascular system is commonly referred to as
preservative fluid
any fluid injected or containing preservatives are referred to
