Breath Sounds + Auscultation Flashcards
Vesicular breath sounds Normal/abnormal: Created by: Description: Location: Phase: Ratio:
Normal/Abnormal: Normal
Created by: air moving in/out of bronchioles/small air passages
Description: Gentle rustling
Location: Normal lung tissue, most of chest wall
Phase: Insp + exp
Ratio: Insp > exp
Bronchovesicular breath sounds Normal/abnormal: Created by: Description: Location: Phase: Ratio:
Normal/abnormal: normal
Created by: trachea and large bronchi
Description: louder than vesicular, higher pitch
Location: 1st/2nd intercostal space by sternum, between scapulae
Phase: insp, exp
Ratio: insp = exp with slight pause
Bronchial breath sounds Normal/abnormal: Created by: Description: Location: Phase: Ratio:
Normal/abnormal: abnormal
Created by: vibration of air in traceobronchial system
Description: blowing, hollow character
Location: over-lung pneumonia, consolidation
Phase: insp, exp
Ratio: exp > insp
Abnormal bronchovesicular breath sounds Normal/abnormal: Created by: Description: Location: Phase: Ratio:
Normal/abnormal: abnormal
Created by: mixture of consolidated and aerated lung
Description: loud rustling
Location: heard in area of lung that should have vesicular breath sound
Phase: insp, exp
Ratio: insp = exp
Decreased or absent breath sounds Normal/abnormal: Created by: Description: Location: Phase:
Normal/abnormal: abnormal
Created by: fluid or air in pleural space, fibrosis, emphysema, bronchial obstruction, decreased flow
Description: decrease intensity/loudness but no change in character
Location: any part of the lung
Phase: insp, exp
Crackles Heard during resp cycle? Probable cause? Quality? Pathological cause?
Heard during resp cycle? insp
Probable cause? rest/obst lung disease, movement of secretions
Quality? bubbles bursting
Pathological cause? atelectasis, pul, edema, fibrosis, pleural effusion, pneumonia, CHF
Wheezes Heard during resp cycle? Probable cause? Quality? Pathological cause?
Heard during resp cycle? more often on EX
Probable cause? airway obstrcution
Quality? high or low pitch
Pathological cause? bronchospasm or secretion narrow airway
Pleural rub Heard during resp cycle? Probable cause? Quality? Pathological cause?
Heard during resp cycle? IN or EX
Probable cause? pleural inflammation
Quality? sandpaper or leather rubbing together
Pathological cause?
Apnea
Absence of ventilation
Fish mouth
Apnea with mouth opening and closing
Eupnea

Increase then decrease depth with apnea
somewhat regular rhythm
(Critically ill patients)
