WEEK 12 PTA152 Normal Breath Sounds

NORMAL SOUNDS

*Loud "Tubular Sounds"

*High Pitched

-Inspiration & Expiration

-Pause between the two

• Tracheal & Bronchial

• Vesicular Sounds

​ (a)  

-Auscultate Lung Segments

-Patient says "​ (b)   "

-Distal segments sound like "​ (c)   "

• Egophony
• e
• a
• Bronchophony
• Crackles
• Wheezes

​ (a)  

-Ausculature Lung Segments

-Patient say "​ (b)   "

-Clearly Audible -->​ (c)  

-Less Audible/Softer/Weaker --> ​ (d)  

• Bronchophony
• 99
• Lung Consolidation
• Hyperinflation
• Egophony

-Ausculate Lung Segements

-Patient whispers words/phrases

-Clearly Audible --> Lung Consolidation

-Less Audible/Softer/Weaker --> Hyperinflation

• Whispering Pectoriloquy

• Bronchophony

• Egophony

Geriatric Considerations

-​ (a)   elasticity of the lungs

-Decrease strength of ​ (b)  

-Increased wall stiffness

*rib and vertebrae ​ (c)  

*stiff intercostals cartilage

Pulmonary Function Testing

-Decreased​ (d)  

-Decreased inspiratory reserve

-Decreased expiratory reserve

• Decreased
• diaphragm
• arthritis
• vital capacity

HIGHER RISK OF RESPIRATORY ILLNESS

• Pediatric

• Geriatric

Pediatric Structure

• Decreased airway size

• Mechanical disadvantage

• Higher risk of respiratory illness (compared to adults)

• Decrease elasticity of the lungs

NGSS.HS-LS1-3

Pediatric Smaller Structure

-Increased metabolic rate --> ​ (a)  

-Increased Heat Loss & Water Loss

**Age-Appropriate Activities

• Decrease elasticity of the lungs

• Needs more O2
• Needs less O2

Structural Changes for Geriatric Considerations

• Decrease elasticity of the lungs

• Decrease strength of diaphragm

• Increased wall stiffness

  *rib and vertebrae arthritis

  *stiff intercostal cartilage

• Decrease airway size

Pulmonary Function Testing

-​ (a)  

-Decreased inspiratory reserve

-​ (b)   expiratory reserve

• Decreased vital capacity
