Emergency Care 13th Edition Chapter 7 Flashcards

10163299386	Aerobic metabolism	The cellular process in which oxygen is used to metabolize glucose. Energy is produced in an efficient manner with minimal waste	0
10163299387	Anaerobic metabolism	the cellular process in which glucose is metabolized into energy without oxygen. Energy is produced in an inefficient manner with many waste products.	1
10163299388	Cardiac output	the amount of blood ejected from the heart in one minute (heart rate x stroke volume)	2
10163299389	Chemoreceptors	chemical sensors in the brain and blood vessels that identify changing levels of oxygen and carbon dioxide	3
10163299390	Dead air space	air that occupies the space between the mouth and alveoli	4
10163299391	Dehydration	an abnormally low amount of water in the body	5
10163299392	Diaphoresis	cool, pale, and moist/sweaty skin; sweating	6
10163299393	Edema	swelling associated with the movement of water into the interstitial space	7
10163299394	Electrolyte	A substance that, when dissolved in water, separates into charge particles	8
10163299395	FiO2	fraction of inspired oxygen; the concentration of oxygen in the air we breathe	9
10163299396	Hydrostatic pressure	the pressure within a blood vessel that tends to push water out of the vessel	10
10163299397	Hypersensitivity	an exaggerated response by the immune system to a particular substance	11
10163299398	Hypoperfusion	inability of the body to adequately circulate blood to the body's cells to supply them with oxygen and nutrients. A life-threatening condition. Also called shock.	12
10163299399	Metabolism	The cellular function of converting nutrients into energy	13
10163299400	Minute volume	The amount of air breathed in during each respiration multiplied by the numbers of breaths per minute	14
10163299401	Patent	open and clear; free from obstruction.	15
10163299402	Pathophysiology	The study how disease processes affect the function of the body.	16
10163299403	Perfusion	The supply of oxygen to and removal of wastes from the cell and tissues of the body as a result of the flow of blood through the capillaries.	17
10163299404	Plasma oncotic pressure	the pull exerted by large proteins in the plasma proteins in the plasma portion of the blood that tend to pull water from the body into the bloodstream.	18
10163299405	Shock	see hypoperfusion	19
10163299406	stretcher receptors	sensors in the blood vessels that identify internal pressure	20
10163299407	stroke volume	the amount of blood ejected from the heart in one contraction	21
10163299408	systemic vascular resistance	the pressure in the peripheral blood vessels that the heart must overcome to pump blood into the system	22
10163299409	tidal volume	the volume of air moved in one cycle of breathing.	23
10163299410	V/Q match	ventilation/perfusion match. This implies that the alveoli are supplied with enough air and that the air in the alveoli is matched with sufficient blood in the pulmonary capillaries to permit optimum exchange of oxygen and carbon dioxide	24
10163299411	Nucleus	Cellular structure that contains DNA	25
10163299412	Cell Membrane	Part of the cell that allows substance in and out of the cell	26
10163299413	Endoplasmic Reticulum	Plays a key role in synthesizing proteins	27
10163467398	Cardiopulmonary System	Respiratory & Cardiovascular System	28
10163682055	Plasma	liquid potion of blood -blood transports O2 & CO2 by dissolving it into the plasma	29
10163722644	edema	swelling resulting from a buildup of fluid in the body tissues	30
10164336827	Sepsis	high altitude	31
10164394001	bradycardia	too slow heart rate	32
10164394858	tachycardias	too fast heart rate	33
