1

causes of increased airway resistance

-contraction of bronchial smooth muscle- asthma
-thick bronchial secretions- chronic bronchitis
-obstruction of airway-tumor, foreign object
-loss of lung elasticity-emphysema

2

ventilation

movement of air in and out of the airways

3

perfusion

the actual blood flow through the vasculature

4

pulmonary diffusion

the process of oxygen and co2 are exchanged

5

what is lung compliance

the elasticity and expandability of the lungs and thoracic structures

6

what is shunting

shunting is when blood is being drained into the left side of the heart with out aveolar gas exchange

7

dyspnea

SOB difficulty breathing

8

what indicated a sudden onset of dyspnea

pneumothroax, acute respiratory obstruction, allergic reaction, MI,
in immobilized PTs may indicate PE

9

what may indiacted ARDS

dyspnea, tachypnea, with hypoxemoia in patients with lung trauma, shock, cardiopulmonary bypass, or mutiple blood transfusions

10

a cough w/ sputum in the AM may indicate what?

bronchitis

11

a cough @ night may indicate what?

onset of left sided heart failure or bronchial asthma

12

a change in sputum color may be a sign of

infection

13

pink tinged may indiacate

lung tumor

14

profuse frothy pink material may indiacte

pulmonary edema

15

risk factors of respiratory disease

smoking, second hand smoke
vit D deficiency
gentic makeup
fam history of lung disease
expose to allergens, or occupational hazards

16

difference betwn pulmonary central cyanosis and periperheal cyanosis

pulmonary is observed by color or tongue and mouth
peripheral is observed by fingers toes earlobes

17

what is health lung tissue called

resonance

18

abnormal breath sounds( adventitous)

crackles( course, fine)
wheezing
friction rub

19

risk factors of hypoventilation

neurologic disorders such as spinal cord trauma CV accident, tumors, pollio, drug overdose
depressed respiratory centers from sedation, opioids, anestheia
limited thoracic movement, plueral effusion, pneumothroax, pulm edema, COPD

20

what is hypoexemia

decrease in the arterial oxygen tension in the blood, manifested by changes in mental status, dyspnea, increse BP, change in HR, dysrhythmias, sweating, cool extermities,

21

hypoxia

decreased oxygen supply to tissues

22

indicators of inadequate oxygen

confusion, restlessness, tachycarida, tachypnea, diaphoresis, lesthargy, HTN, pallor

23

what is oxygen toxicty

when too high a concentration of oxygen given for extended period of time( > 48hrs)

24

S&S of toxicity

substernal discomfort,paresthesia, dyspnea, fatigue, restlessness, malasia, resp difficulty.

25

ways to reduce atecelactasis infection

humidifiers postural drainage, chest percussion, and bronchodilators

26

risk factors to surgery related atecelactasis preop

age, obesity, poor nutrition, smoking hx, preexisting lung disease, abnorm pulmoary fxn test, ER situation

27

risk factors to surgery related atecelactasis intraop

throacic incision, prolonged anesthesia

28

risk factors to surgery related atecelactasis postop

immobilized, supine positon, decreased LOC, inadequate pain management, NG tube, inadequate dee breathing
