How many lobes does the R lung have?
3
How many lobes does the R lung have?
2
How high does the lung apex rise on the anterior chest?
2-4cm above the inner 1/3 of the clavicle
How low does the inferior border of the lung extend?
6th rib at mid-clavicular line & 9th rib at mid-axillary line
What are the borders of the lungs on the posterior?
Lower lungs mostly -T3 to T10 or 12
Where is the right middle lung lobe?
Anterior, between 4th and 6th rib. Lies between the horizontal fissure and the oblique fissure.
What is the angle of Louis?
Junction of manubrium and sternum. Attaches the 2nd ribs. Palpable landmark.
What is a VESICULAR breath sound and where is it heard?
Soft, low pitched, breezy. Over healthy lung tissue.
What is a BRONCIAL breath sound and where is it heard?
High-pitched, harsh, loudest. Heard over the trachea and bronchi. Abnormal if heard over peripheral lung tissue.
What is a BRONCHOVESICULAR breath sound and where is it heard?
Medium-pitched & intensity. Heard over major bronchi. Abnormal if heard over peripheral lung tissue.
What is a TRACHEAL breath sound and where is it heard?
High-pitched, harsh. Over trachea and neck. Think Darth Vadar.
Discontinuous breath sounds
Fine or course crackles. High (fine) or low (course) pitched discrete crackling sounds during inspiration. Not cleared by cough.
Continuous breath sounds
1) Ronchi: loud, low, course like a snore, inspiration or expiration, coughing may clear (d/t mucus)
2) Wheeze: musical or squeaking, continuous during inspiration or expiration
Pleural friction rub
Dry, rubbing, grating during inspiration or expiration. Inflammation of pleural survacles
Chest percussion: where should you hear resonance?
All areas of healthy lung tissue
Chest percussion: why would you hear hyperresonance?
Hyperinflation -emphysema, pneumothoras, asthma
Chest percussion: why would you hear dullness or flatness?
Abnormal findings: Pneumonia, atelecstasis, pleural effusion, pneumothorax, asthma
Normal findings: over heart, diaphragm, or bones of scapula or bigger muscles
Percussion: where would you here tympany?
Abdomen
Define bronchophony
Greater clarity and increased loudness of spoken sounds with auscultation
Define whispered pectoriloquy
Extreme bronchophony where a whisper is amplified.
Define egophony
Nasally distortion of spoken words heard through auscultation.
What do bronchophony, whispered pectriloquy and egophony indicate?
Consolidation in the lungs
What would diminished vocal resonance indicate?
Loss of tissue within respiratory tree
What is a normal diaphragmatic excursion?
3-6cm. **diaphragm normally higher on right d/t liver
What would cause a diminished diaphragmatic excursion?
Pulmonary problems: emphysema
Abdominal problems: ascites, turmor
Superficial: fractured rib
Normal A/P diameter
A/P should be about .7-7.5 of lateral diameter
Increased A/P diameter
Increases with age. Equal to lateral diameter indicates chronic condition.
Where do the bronchi bifurcate?
2nd intercostal space
What would decreased tactile fremitis indicate?
Excess air in lungs, emphysema, pleural thickening, effusion, massive pulmonary edema, bronchial obstruction.
What would increased tactile fremitis indicate?
Fluids or solid mass in lungs d/t consolidation, heavy bronchial secretions, compressed lung, tumor.
Barrel chest
D/t compromised respiration (chronic asthma, emphysema, CF). Ribs become horizontal, spine become kyphotic, prominent sternal angle.
Flail chest
A flapping, unfixed chest wall caused by loss of stability of the thoracic cage after fracture of the sternum and/or ribs. A symptom is paradoxical movement of a portion of the chest wall—that is, the affected area draws in when the patient breathes in and the rest of the chest expands, and the affected area moves outwards as the patient exhales and the rest of the chest contracts.
Scoliosis
Lateral curvature of the spine
Kyphosis
Increased convex curvature of thoracic spine
Gibbus
Similar to kyphosis but with an extreme sharp angular deformity in the mid-thoracic region
Lordosis
Accentuation in lumbar curvature of spine
Pectus carinatum/excavatum
Carinatum: forward protrusion of sternum (pigeon chest)
Excavatum: Depression of sternum (funnel chest), may cause fatigue SOB, pain, tachycardia
Cough
Forceful expiration that clears irritants/secretions. Note: dry or moist, rapid or slow onset, frequency, regularity, pitch, postural influences, quality.
Sputum production
Mucus material from lungs brought up by coughing. Any more than a small amount of sputum suggests disease. Acute onset: infection. Chronic problem: indicates anatomic change.
Hemoptysis
Coughing up blood
Dyspnea
Difficulty breathing
