respir sounds

Question 1

Fe Asthma

Answer 1

Expiratory effort = lower airway obst

if fast, hard to tell phase

wheezes on expiration due to narrowed airways

+/- Paradoxical breathing

Question 2

bact pneumonia

Answer 2

Mixed inspiratory and expiratory effort = pulmonary parenchymal dis

Incr BV sounds = wet lungs

crackles if alv full of pus

wheezes if airways narrowed d/t mucus

Question 3

pyothorax

Answer 3

Shallow, inspiratory effort
No noises w/o stethoscope

Muffled heart and lung sounds ventrally

No adventitial lung sounds unless also pneumonia

Paradoxical breathing common

Hyporeasonant on percussion

Question 4

idiopathic pul fibrosis

Answer 4

Shallow breaths inspiratory restricted lung dis

Harsh crackles

Pulmonary hypertension may lead to cor pulmonale with tricuspid regurgitaiton

Question 5

pneumothorax

Answer 5

Shallow, rapid inspiratory effort

+/- Muffled lung and heart sounds

Hyper-reasonant on percussion

Depending on cause, no adventitial sounds

Question 6

cardio pul edema

Answer 6

Heart murmur +/- arrhythmia

Mixed inspiratory and expiratory effort = parenchymal disease

Increased BV sounds = wet lungs

Crackles if alveoli full of water, esp after cough

Often orthopnic

Question 7

laryngeal paralysis

Answer 7

Voice change/weak bark
“Horsey” breathing
Overt stridor
Inspiratory effort
