Flashcards in Med Surg I Respiratory Terms Deck (10):
1

Pharynx

the chamber that joins nasal and oral cavities to the esophagus and larynx: part of respiration and digestion

2

Alveoli

one of the furthest structures in the lungs where oxygen and carbon monoxide exchange; elastic balloon-like structures that help with exhalation

3

Bronchial breath sounds

heard over large airways (trachea and larynx) and should be relatively easy to hear (sounds like blowing through a paper towel core)

4

Vesicular breath sounds

May be heard over the smaller airways (bronchioles and alveoli) and are not typically as loud as those heard in the bronchial areas; air filling the smaller, more distal parts of the lungs as compared to the large airways of bronchial breath sounds

5

adventitious lung sounds

abnormal: crackle, wheeze, rhonchus, pleural friction rub
vary in: pitch, intensity, duration, phase of the respiratory cycle

6

atelectasis

when a lung collapses either completely or partially causing reduced or no air exchange in that lung

7

Dyspnea

Shortness of breath

8

Peak expiratory flow

The maximum rate a person can exhale

9

Hypoxemia

Low blood oxygen: can cause SOB

10

Pleura

Serous membrane that wraps the lungs and lines the chest cavity (serous membranes are smooth with cells that secrete serous fluid for lubrication)
