Study Notes

Assessment of Lungs and Thorax

Pattern: Important to ensure coverage of all lung fields and to listen to the lateral portion of the lungs (side of body)

Expected Lung Sounds

Clear lung sounds: Expected normal sound
No adventitious lung sounds: No crackles or wheezing
Bronchovesicular sound: Louder than vesicular, heard closest to bronchi, even on inspiration and expiration
Vesicular sound: Whisper-like sound, louder on inspiration, smaller airway

Adventitious Sounds

Fine crackles: High-pitched crackling
Coarse crackles: Fluid in the lungs, sounds like drinking a drink and reaching the bottom
Pleural friction fremitus: Friction in pleural tissue due to inflammation
Wheeze-sibilant: Obstruction, air escaping through small airway, narrowed
Wheeze-sonorous rhonchi: Obstruction, air escaping through small airway, narrowed on exhale
Stridor: Upper airway obstruction, something lodged in throat, common in children

Respiratory Rate, Rhythm, and Pulse Oximetry

Respiratory rate and rhythm: Regular, even, effortless, symmetric, consistent, 12-20 breaths per minute
Pulse oximetry: Noninvasive method to assess arterial oxygen saturation (SPO2), normal values: 97%-99%

Inspection

Respiratory rate and rhythm: 12-20, consistent, even, regular
Chest rise and fall: Symmetrical, no accessory muscle use or retractions
Comfortable positioning: No tripod position, no cyanosis
Chest wall configuration: Normal: AP:T is 1:2, abnormal: AP:T 1:1, barrel chest, irreversible
Nails: Abnormal: clubbing caused by chronic hypoxia
Posterior thorax: Abnormal: asymmetry and dorsal curvature, scoliosis, kyphosis, gibbus

Palpation

What to feel for: Abnormal findings: crepitus, friction, masses, temperature, normal findings: warm, no masses or tenderness
Technique: Hands move with breathing starting at T9 vertebrae, go from left to right to down and then right to left motions
Tactile Fremitus: palpable vibration, sounds generated from larynx, symmetric

Percussion

Client position: Slightly bent forward
Compare bilaterally: Note any symmetry, avoid body prominences
Specific technique: Start at apices and go side-to-side, working way down
Findings: Normal: resonance (low-pitch, clear, and hollow sound), abnormal: dull, can indicate fluid in lungs, pneumonia, or tumor

Auscultation

Position: Sit upright, relaxed, hands on knees
How to breathe: In and out of mouth every time stethoscope makes contact with skin
How far down to listen: To lateral part of back
Place on foot (for babies), finger, or toe: Inaccurate readings can be caused by carbon monoxide binding to Hgb instead of oxygen or anemia
