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
