Emergent phase

Back 6

first stage of the burn process that is characterized by a catecholamine release and pain-mediated reaction

Front 7

Fluid shift phase

Back 7

Stage of burn process in which there is a massive shift of fluid from the intravascular space to extravascular space
up to 24 hours
peak reached at 6-8 hours

Front 8

Hypermetabolic phase

Back 8

stage of the burn process in which there is an increase in metabolism in an attempt by the body to heal the burn

Front 9

Resolution phase

Back 9

final stage of the burn prodcess in which scar tissue is laid down and the healing process is completed

Front 10

Front 13

Voltage

Back 13

difference of electrical potential between two points with different concentration of electrons

Front 14

current

Back 14

The rate of flow of an electrical charge

Front 15

property of a conductor that opposes the passage of electrical energy

Front 17

Ohm

Back 17

basic unit for measuring the strength of electrical resistance

Front 18

Joule's law

Back 18

the physical law stating the rate of heat production is directly proportional to the resistance of the circuit and to the square of the current

Front 19

Coagulation necrosis

Back 19

the process in which an acid, while destroying tissue, forms an insoluble layer that prevents further damage

Front 20

Liquefaction necrosis

Back 20

the process in which an alkali dissolves and liquefies tissue

Front 21

Ionizing radiation

Back 21

electromagnetic radation (x-ray) or particulate radation (alpha, beta particles and neutrons)

Can penetrate body cells and kill them with enough dosage

Front 22

Types of Radiation

Back 22

Alpha: weak, stopped by minor objects, clothing or epidermis

Beta: more powerful than alpha

Gamma: most powerful ionizing radiation
Great penetrating power and requires thick concrete or lead shielding

Back 25

Hypothermia
Hypovolemia
Eschar
Infection
Organ Failure

Front 26

Clean vs. Dirty Radiation Exposure

Back 26

Clean: exposed to radtion but not contaminated by radioactive particles, liquids, gases or smoke

Dirty: contaminated by radioactive particles.

Front 31

Airway Thermal Burn

Back 31

Mostly upper airway due to absorption of heat.

Front 32

Superheated steam
