pulmonary/ chest assessment Flashcards
Bony ridge that joins the manubrium and sternal body
Angle of Louis
Major oblique fissure divides each lung in half and goes from ____ spinous process obliquely around chest to ____ rib at midclavicular line
T3, 6th
precordial crackles in sync with heartbeat, not respiration
mediastinal crunch (hammans sign)
purpose of auscultation for egophony
assess underlying lung tissue for collapse/ consolidation
purpose of auscultation
determine whether there is normal air-flow, airway obstruction, or abnormal air or fluid w/in chest/lungs
location of broncho-vesicular breath sounds
ant- 1st and 2nd interspaces post- interscapular
subQ crepitus caused by
subQ emphysema (rice krispies under skin)
increased fremitus (vibration) seen with
pneumonia/ consolidation
accessory muscle use
signs of resp distress SCM, scalene, supraclavicular contraction COPD, asthma
subQ emphysema
air from lung/ chest tracks along tissue planes
alveoli filled with fluid blood/ pus increasing the density and opacity of the lung tissue
consolidation/ infiltrate
expiration
diaphragm relaxes, chest wall contracts, intrathoracic pressure normalizes
stridor
high pitched, wheeze obstruction in trachea or larynx foreign body/ airway disease croup (kids)
inspection- chest size/shape/color
lesions, scars, color chest A- P diameter, deformity, body habitus
crackles/ rales heard when
small airways pop open during inspiration or when air bubbles flow through secretions or closed airways
pectus excavatum
concave anterior chest
mediastinal crunch is a sign of
mediastinal emphysema (pneumomediastinum)
egophony positive presence indicates
lung consolidation/ collapse eg PNA, atelectasias, tumors
resonant sounds
over air (lungs)
wheeze is heard with
asthma, COPD, chronic bronchitis, bronchus obstruction
ex of dull
pneumonia pleural effusion
intensity and pitch of broncho-vesicular breath sounds
moderate, moderate
rhonchi sound
low pitched, snoring, “wheeze” large airway secretions (chronic bronchitis)
specialized exams for auscultation
bronchophony and egophony
