28
inspiratory reserve volume (IRV)
max volume of air that can be inspired after normal tidal volume inspiration

31
Residual volume (RV)
volume of gas remaining in lung after max expiration. 25% of lung volume
32
Tidal volume (TV)
total volume of inspired and expired with each breath during quiet breathing. approx. 10% of total lung volume
33

46
Crackles (rales)
discontinuous high pitched popping sound head usually during inspiration. may be associated with restricted or obstructive disorders. Represents the movement of fluid or secretions during inspiration
47
Pleural Friction Rub
Dry crackling sound heard during both inspiration and expiration. Occurs when inflamed viscera and parietal pleura rub together.
48
Rhonchi
continuous low pitched sound (snoring/gurgling). caused by air passing through an airway which is obstructed by secretions or liquid
49
Stridor
high pitched wheeze with inspiration or expiration. indicates airway obstruction(think Peds)
50
Wheeze
musical or whistling sound. heard during inspiration and expiration. arise from turbulent airflow
