1

action of a force against an opposing force (a force applied or acting against resistance).

PRESSURE

2

whatever pressure is necessary to overcome initial vascular resistance and distribute embalming solution to all areas of the dead human body (ideal pressure) – adjective to describe pressure

Recommended (ideal) pressure

3

speed at which fluid is injected measure in ounces per minute.Controlled by a valve on the embalming machine which controls the flow of fluid muck like a water faucet.

RATE OF FLOW

4

– that which will ensure uniform distribution without causing (promoting) over distention (swelling).

Ideal rate of flow

5

PSI stands for

pounds per square inch

6

METHODS OF CREATING PRESSURE

1. Gravity Injector Method 2. HAND PUMP 3. Bulb Syringe 4. Motorized Force Pump

7

a method of creating pressure; consist of a glass bottle (PERCOLATOR), rubber tubing and a device to suspend the bottle above the point of injection

Gravity Injector Method

8

Pressure is increased _____________for every foot of elevation above the point of injection.

.43 pounds, (approximately ½)

9

how many inches (feet) above injection creates 1 pound of pressure

28 inches (2.33 feet)

10

how many inches (feet) above injection creates 2 pound of pressure

56 inches (4.66 feet)

11

how many inches (feet) above injection creates 3 pound of pressure

84 inches (7.00 feet)

12

The percolator is elevated 5 feet above point of injection, how much injection pressure is created? lbs.

5 x .43 = 2.15

13

To create 3 pounds of injection pressure how many feet, above the point of injection would the percolator need to be raised?

3 / .43 = 6.97 feet.

14

a method of creating pressure; consist of a hand operated pump, tubing and a goose neck arrangement and glass fluid bottle. This apparatus is used for creating injection pressure can be used for aspiration.Over sized hypodermics syringe attached to bottle and used to create injection pressure or create pressure for aspiration.

HAND PUMP

15

a method of creating pressure; used in combo with hand pump or percolator. Self contained soft rubber, manual pump. Used only to deliver fluid. Simplest form of injection apparatus, consist of a bulb type rubber syringe and rubber tubing.

Bulb Syringe

16

a method of creating pressure; (centrifugal) – most commonly used method of creating injection pressure.

Motorized Force Pump

17

Types of Motorized Force Pump

PULSATING and NON-PULSATING

18

type of motorized force pump; fluid is injected in spurts

pulsating

19

type of motorized force pump; fluid is injected on a continuous basis

non-pulsating

20

pressure indicated by the injector gauge needle when the injector motor is running and the arterial tubing is clamped off

Potential Pressure

21

pressure indicated by the injector gauge needle when the arterial tube is open and the arterial solution is flowing into the body. (Does not mean the actual pounds per pressure)

Actual Pressure

22

difference between potential and actual pressures. P-A=DThis is the actual pressure at which the fluid is flowing into the dead human body

Differential Pressure

23

Considerations for Force Pump

ReliableWide pressure range- same as a high as 200 pounds. Constant pressureLarge unit volume- usually at least three gallons.

24

Precautions for force pumps

Needs frequent servicing Requires constant attention of the operator.

25

FACTORS AFFECTING INJECTION PRESSURE Intravascular Influence

1. Condition of the vessels- normal versus sclerotic. 2. Local congestion of blood in the area- prevents the flow of additional fluid in an area

26

FACTORS AFFECTING INJECTION PRESSUREExtravascular influence

1. Weight on the viscera- pressing mainly on the descending aorta.- *if embalming from the femoral – viscera will be embalmed first causing problems for circulation toward the head. Viscera may begin to harden.2. Gas in the viscera – pressure against the descending aorta.3. Tumors – pressing against the outside wall of the arteries4. Ascites – excess fluid in the peritoneal cavity, not inside the blood vessels. Substance that has clear amber or straw colored fluid released when trocar is inserted into the body5. Contact pressure – bandages, clothing, etc., also – contact with certain areas of the body with the embalming table and positioning devices.6. Edema of the extremities – caused by heart or kidney failure or venous obstruction.7. Swollen ankles or tissue may have complications during embalming.

27

the length of time between death and embalming

POST MORTEM INTERVAL

28

postmortem interval

1. Presence of Rigor Mortis – body is highly acidic, once rigor is relieved body is alkaline again.2. State of decomposition – still attempt vascular embalming, always try to keep decomposition from advancing any further.3. Discoloration – blood pools to the lower region of the position of the body.4. Livor Mortis or Cadaveric Lividity

29

The dilution attained as the embalming solution is mixed in the embalming machine. This is determined by the embalming analysis and prepared by the embalmer.

Primary Dilution

30

To determine the strength of a primary dilution, the following formula may be employed:

C × V = C’ × V’ (c prime × v prime)
