Anesthesia Terms and Concepts Flashcards
acute
condition that has a rapid or recent onset
patient that is hypertensive from postoperative pain has acute hypertension
chronic
condition that has been present for a long time
patient that dakes daily antihypertensives to treat blood pressure has chronic hypertension
angina
chest pain
common/serious cause: blocked coronary artery
arrhythmia
abnormal heart rhythm,
atelectasis
collapsed alveoli
commonly caused by hypoventilation
atherosclerosis
buildup of fatty plaques
cause narrowing of artery
cause decreased blood flow through artery
coronary artery: angina, ischemia, heart attack
head: stroke
auscultation
listening (with stethoscope)
bariatric
obese
contraindication
situation in which a drug, procedure, or surgery should not be used because it may be harmful to the person
ex. performing labor epidural is contraindicated in patient with lumbar infarction
cyanosis
“blueness” of skin due to lack of oxygen delivery to the tissues
diaphoresis
sweating
distal
away from center of body
diuresis
urine excretion
endentulous
has no teeth (uses dentures)
Ejection Fraction (EF)
percentage of the volume that is pumped out of the left ventricle with each heart beat
Normal EF
65-75%
Low EF
heart failure
elective surgery
planned, non-emergency
(can wait if needed)
embolism
moving blood clot
epistaxis
nose bleed
erythema
reddening of the skin (in patches) as a result of injury or irritation, causing capillary dilation
etiology
cause of disease or symptoms
exsanguinate
to be drained of blood
febrile
patient has a fever
temp > 38C
FiO2 acronym
Fraction of Inspired Oxygen
FiO2 definition
concentration of oxygen in the air we breath
Room Air FiO2
21%
(the concentration of oxygen we normally breathe is 21%)
Oxygen mask FiO2
60-90%
geriatric
elderly
global
some that occurs throughout the body
regional
only occurs in one area of the body
gtt
infusion of a drug or fluid
hypercarbia
(hypercapnia)
elevated plasma CO2 concentration
hyperkalemia
elevated plasma potassium (K+) concentration
>5.5mEq/L
hypernatremia
elevated plasma sodium (Na+) concentration
>145mEq/L
hypertension
elevated blood pressure (BP)
>140/90 mmHg
hyperthermia
elevated body temp
hypocarbia (hypocapnia)
low partial pressure of CO2 in plasma
<35mmHg
hypokalemia
low plasma potassium
<3.5mEq/L
hypotension
low blood pressure
<90/50mmHg
hypothermia
lower than normal temp
<36 C
hypovolemia
low blood volume
hypoxia
poor oxygen delivery or oxygenation
latrogenic
condition induced inadvertently by medical treatment or diagnostic procedures
IM (intramuscular)
injecting a drug into the muscle
deeper than subcutaneous
ischemia
insufficient oxygen supply to an organ
O2 demand increase
Blood flow lacking
Ventilation insufficient
myocardial infaction
heart attack
lack of blood flow and o2 to the heat causes area of heart muscle to die
NPO
nil per os
nothing by mouth
no solid foods 6-8 hrs
no clear liquids 2 hrs
prior to surgery
peripheral
outer region
away from center
paraoxysmal
sudden increase or return of symptoms
