Flashcards in Cardiovascular Deck (25):
1

stroke volume

amount of blood ejected with each heartbeat

2

preload

degree of stretch of cardiac muscle fibers at the end of diastole

3

afterload

resistance to ejection of blood from ventricle

4

contractility

ability of cardiac muscle to shorten in response to electrical impulse

5

stable angina

chest pain precipitated by exertion or stress. Myocardial oxygen demands increaed

6

unstable angina

(preinfarction) chest pain occuring at rest

7

inractalb e

severe

8

silent ischemia

diabetics

9

prinzmetal angina

vasospasm

10

angina is

due to insufficient coronary blood flow to the heart leading to less oxygen to the cardiac tissue

11

left side heart failure

results in pulmonary congestion

12

right side heart failure

jugular vein distention, systemic symptoms swelling

13

how do you treat pulmonary edema

oxygen therapy, diuretics, vasodilators, position patient upright, legs over side of bed to decrease venous congestion

14

pre-hypertension

120-139/80-89

15

stage 1 hypertension

140-159/90-99

16

stage 2 hypertension

greater than 160/100

17

Major risk factors for hypertension

smoking, obesity, inactivity, diabetes, family history, older age

18

organ damage for hypertension

retinal changes, renal damage, mi, stroke, heart enlargement

19

cholesterol desirable range

200/mg/dl fasting

20

triglycerides desirable range

150/mg/dl fasting

21

atelectasis

closure or collapse of alveoli

22

acute atelectasis

acchycardia, tachypnea, pleural pain, central cyanosis if large areas of the lung are affected

23

chronic atelectasis

similar to acute, pulmonary infection may be present

24

how do you prevent atelectasis

frequent turnings, early mobilization, incenive spirometer, voluntary deep breathing, secretion management

25

what is our main objective with atelectasis

improve ventilation and remove secretions
