Wheezing is caused by obstruction located …. and is usually only heard during …. ?
within the thoracic cavity … expiration
polyphonic wheeze is usually heard with?
asthma
monophonic wheeze is usually heard with?
focal obstruction rather than asthma
Describe rhonci
Coarse, low-pitched rattling sounds heard best in expiration.; Thought to be due to secretions and narrowing of airways.
Râles are a.k.a. and occur during … ?
crackles, usually heard during inspiration (vs. rhonci heard at end expiration)
Imaging studies for suspected foreign body aspiration?
Bilateral lateral decubitus or inspiratory/expiratory chest films
What is the rational behind the inspiratory/expiratory chest film for suspect FBA?
airway containing an obstruction does not allow the distal lung to deflate fully and results in asymmetric deflation with expiration
What is the rational behind the decubitus chest film for suspect FBA?
child lying on her side. The concept of the lateral decubitus film is that the dependent lung should deflate slightly compared to the non-dependent lung due to the effect of gravity. If each lung deflates slightly when dependent as expected, there is less likelihood of an obstruction in a large airway. If one side does not deflate as expected, this suggests an obstruction in a large airway.
In well controlled asthma, SABA should not be required more than … times per week.
