Embalming 2 Final Exam Flashcards
action of a force against an opposing force (a force applied or acting against resistance).
PRESSURE
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
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
– that which will ensure uniform distribution without causing (promoting) over distention (swelling).
Ideal rate of flow
PSI stands for
pounds per square inch
METHODS OF CREATING PRESSURE
- Gravity Injector Method 2. HAND PUMP 3. Bulb Syringe 4. Motorized Force Pump
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
Pressure is increased _____________for every foot of elevation above the point of injection.
.43 pounds, (approximately ½)
how many inches (feet) above injection creates 1 pound of pressure
28 inches (2.33 feet)
how many inches (feet) above injection creates 2 pound of pressure
56 inches (4.66 feet)
how many inches (feet) above injection creates 3 pound of pressure
84 inches (7.00 feet)
The percolator is elevated 5 feet above point of injection, how much injection pressure is created? lbs.
5 x .43 = 2.15
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.
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
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
a method of creating pressure; (centrifugal) – most commonly used method of creating injection pressure.
Motorized Force Pump
Types of Motorized Force Pump
PULSATING and NON-PULSATING
type of motorized force pump; fluid is injected in spurts
pulsating
type of motorized force pump; fluid is injected on a continuous basis
non-pulsating
pressure indicated by the injector gauge needle when the injector motor is running and the arterial tubing is clamped off
Potential Pressure
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
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
