Breath sound 複習

在兒急聽了一周還是沒什麼心得……

• Vesicular breath sounds

• 正常肺的周圍
  
• 吸氣比呼氣長且大聲

• Bronchial breath sounds
  

• 正常肺靠中線的聲音
• Consolidation
• 呼氣比吸氣大聲且長(tubular quality)
• 由於consolidation的部份聲波傳導較好，使中線的bronchial sound傳到peripheral
  

• Crackles

• 間斷性的聲音
• Fine crackles = moist rales
• Coarse crackles
• Interstitial lung disease
• microatelectasis
• liquid filling of alveoli: pneumonia; pulmonary edema

• Wheezes

• Bronchospasm
• Airway edema or collapse
• Endobronchial obstruction by neoplasm or secretion
• localized monotonic wheeze較有可能是tumor所造成
  

• Rhonchi

• airway裡有free liquid
• 低頻的震動音
