1
Q

Pathophysiology

A

the study of how disease processes affect the function of the body

2
Q

metabolic

A

the cellular function of converting nutrients into energy.

3
Q

electrolyte

A

a substance that, when dissolved in water, separates into charged particles

4
Q

aerobic metabolism

A

the cellular process in which oxygen is used to metabolized glucose. Energy is produced in an efficient manner with minimal waste products

5
Q

anaerobic metabolism

A

the cellular process in which glucose is metabolized into energy without oxygen

6
Q

FiO2

A

fraction of inspired oxygen in the air we breath

7
Q

patent

A

open and clear

8
Q

tidal volume

A

the volume of air moved in one cycle of breathing

9
Q

minute volume

A

the amount of air breathed in during each desperation multiplied by the number of breaths per minute

10
Q

dead air space

A

air that occupies the space between the mouth and alveoli but that does not actually reach the area of gas exchange

11
Q

chemoreceptors

A

chemical sensors in the brain and blood vessels that identify changing levels of oxygen and carbon dioxide

12
Q

plasma oncotic pressure

A

the pull exerted by large proteins in the plasma portion of blood that tends to pull water from the body into the bloodstream

13
Q

hydrostatic pressure

A

the pressure within a blood vessel that tends to push water out of the vessel

14
Q

stretch receptors

A

sensors in blood vessels that identify internal pressure

15
Q

systemic vascular resistance SRV

A

the pressure in the peripheral blood vessels that heart must overcome in order to pump blood into the system

16
Q

stroke volume

A

the amount of blood ejected from the heart in one contaction

17
Q

cardiac output

A

the amount of blood ejected from the heart in 1 minute

18
Q

V/Q match

A

ventilation/perfusion match

19
Q

perfusion

A

the supply of oxygen to, and removal of wastes from, the cells and tissue of the body as a result of the flow of blood through the capilairies

20
Q

hypoperfusion

A

inability of the body to adequately circulate blood to the body s cells to supply them with oxygen and nutrients. SHOCK

21
Q

dehydration

A

an abnormally low amount of water in the body

22
Q

edema

A

swelling associated with the movement of water into the interstitial space

23
Q

hypersensivity

A

an exaggerated response by the immune system to a particular substance
