Flashcards in 3rd Quarter Embalming 2 Test 1 Deck (159)
They are injected to disinfect, temporarily preserve and restore the dead human body without causing objectionable change in the tissues.
Vascular (arterial) fluids
Generally classified by index: (the number of grams of formaldehyde gas dissolved in 100 ml of water; usually given in a percentage).
Vascular (arterial) fluids
Arterial fluid classification by index
Having an index of 28 - 36. Causes a rapid tissue coagulation.Causes a definite degree of firmness, used most often on “special cases.” (decomposition, edema, outgoing, drowning, etc.)37% by weight and 40 % by volume
Having an index of 19 - 27.Sometimes referred to as semi-firming or cosmetic fluid. (Oil based / cosmetic fluid).Results in a moderate firming of tissues. Normal Cases
Medium (cosmetic arterial fluid)
Any fluid with an index of 10 - 18. Produces a minimum firmness of tissues.Infant cases or adults 80 lbs or less.An index of 8 is the lowest that it would go.
Chemical which inactivates saprophytic bacteria, renders unsuitable for nutrition the media upon which bacteria thrive, and which will arrest decomposition by altering enzymes of the body as well as converting the decomposable tissue to a form less susceptible to decomposition.
1. Inactivated the chemical group of proteins (muscles)2. Inhibits further decomposition3. Inactivates some enzymes4. Kills some microorganisms – not all5. Destroys odorsThese are actions or methods of __________
General formula (R-CHO) common name Formaldehyde.
HCHO or CH 2 0In its free state it is a gas – soluble in water which forms a formula. Water is the universal solvent. Every solvent has a different saturation rate.
