Lung Exam Flashcards
Trachea bifurcates ?
at the carina at levels of sternal angle anteriorly and T4 spinous process posteriorly
Apex of the lung location?
2-4 cm above the inner 1/3 of clavicle
Anterior-lower border location?
Crosses the 6th rib at midclavicular line & the 8th rib at mid axillary line
Posterior-lower border location?
Lies about level of T10 spinous process
oblique fissure
Divides both lungs roughly in half
T3 spinous process obliquely down & around chest to 6th rib at midclavicular line
horizonatal fissure
R. lung only
Runs close to 4th rib & meets oblique fissure in midaxillary line near 5th rib
Signs in the right upper lung field?
Most certainly originate in RUL
Signs in right middle lung field laterally
Could come from any of three different lobes
Increased Tactile Fremitus
vibration from larynx to chest in enhanced as when consolidation is present (ie. pneumonia)
Tactile Fremetus decreased or absent
vibration from larynx to chest surface impeded (ie. COPD, obstruction, pleural effusion or pneumothorax)
Percussion: Flatness
Theigh
Percussion: Dullness
Liver
Replaces resonance in a consolidated or fluid lung
Heart produces area dullness to left of sternum from 3rd-5th ICS
Dullness of RML pneumonia typically occurs behind right breast
Percussion: Resonance
Normal Lung
Percussion: Hyperresonance
None normally
Percussion: Tympany
Gastric Bubble or puffed out cheeks
Diaphragmatic Excursion
Normal 5-6cm
if level is high, suggests pleural effusion or high diaphragm
Wheeze/Rhonchi
Sibilant rhonchi
Wheeze-relatively high pitched (>400 Hz) with hissing or shrill quality
Sonorous rhonchi
Rhonchi- relatively low pitched (
Stridor
Wheeze that is predominately or entirely in inspiration
Louder in neck than chest wall
Indicates partial obstruction of larynx or trachea
Crackles/Rales
Discontinuous
Intermittent, nonmusical, & brief
Fine crackles-soft, high pitched, very brief (5-10msec)
Coarse crackles-somewhat louder, lower pitched, brief (20-30 msec)
Inspiration—early vs. late
Pleural Rub
Resemble crackles by sound
Often discrete but if numerous can seem continuous
Typically confined to small area of chest wall
Heard in both phases of respiration
