Vocal resonance: Bronchophony, whispered pectoriloquy, egophony

Notes:

AP Diameter: Ratio of chest width front-to-back compared to side-to-side; normal is 2:1
Barrel Chest: 1:1 ratio, seen in COPD due to air trapping
Pectus Excavatum: Scooping out of chest wall, "bowl on chest wall"

Examination for Tactile Fremitus

Patient folds arms across chest.
Ask patient to repeat "ninety-nine" or "one, two, three."
Palpate chest wall bilaterally with ulnar border of hand or palmar base.
Compare vibrations on both sides, moving hands from apex to base.

Pneumothorax

Inspection: Diminished chest movement on affected side.
Palpation: Decreased chest movement, decreased vocal fremitus on affected side.
Percussion: Tympanic note on affected side.
Auscultation: Diminished breath sounds and vocal resonance on affected side.

Lung Sounds and Palpation

Lung parenchyma density affects sound transmission:
- Decreased density: Pleural effusion and pneumothorax cause decreased transmission of lower frequency sound vibrations.
- Increased density: Inflammation and consolidation create a denser medium, leading to increased vocal fremitus and transmission of lower frequency sounds.
Vocal fremitus: Palpable vibrations felt on the chest wall when the patient speaks.
- Increased vocal fremitus: Suggests consolidation (e.g., pneumonia, lung abscess).
- Decreased vocal fremitus: Suggests conditions like pleural effusion, pneumothorax, emphysema/COPD, bronchial obstruction, bronchial asthma.
Vocal resonance: Auscultatory counterpart of vocal fremitus.
- Bronchophony: Louder sound over an area of consolidation.
- Whispering pectoriloquy: Whispered words are heard clearly over an area of consolidation.
- Egophony: Sound frequencies passing through consolidation distort vowel sounds, making "E" sound like "A" or "AAAH."
Rhonchial fremitus: Palpable rhonchi (coarse, rattling sounds).
Pleural fremitus: Palpable pleural rub (scratchy, grating sound).
Examining tactile fremitus:
- Patient folds arms across the chest wall to displace scapulae.
- Patient repeats "ninety-nine" or "one, two, three" in a constant tone.
- Practitioner palpates the chest wall on both sides using the ulnar border of hand or palmar base.
- Begin at the lung apex and move to the same location on the opposite side of the chest wall.

Heart Murmurs in Children

Common, occurring in up to 80% of children.
Most are innocent, but some indicate underlying heart disease.
In infants, 37% of murmurs are associated with congenital heart disease.
Beyond infancy, only about 1% of murmurs are associated with structural heart disease.
All infants should be screened for critical congenital heart disease using pulse oximetry, ideally 24 hours after birth.
Referral to pediatric cardiology is indicated for:
- New murmur in a child >3 years old
- Murmur lasting longer than 6 months without clear explanation
- Presence of heart disease symptoms
- Abnormal heart rhythm
- Concerns about genetic or familial history of heart disease
- Abnormal physical findings
Echocardiography is not routinely needed for evaluation of innocent-sounding murmurs without other concerns. Routine use of ECG, chest x-ray, etc. is not cost-effective for evaluating murmurs without other signs of heart disease.
Emerging technologies like phonocardiography and AI algorithms may aid in murmur evaluation in the future.
