- 17What is tactile fremitus? What differences are you looking for?- Palpable vibrations transmitted from the bronchopulmonary tree to the chest wall
- Look for asymmetrical difference in the intensity of the vibratory sensation - 18What does increased fremitus suggest?- Increased fremitus suggests fluid, mass, or pneumonia

Compare bilaterally moving side to side - 24Percussion note findings over lung fields: What would resonant sounds indicate?Resonant – healthy lung tissue
- 25Percussion note findings over lung fields: What would flat/dull sounds indicate?Flat/Dull – effusion or consolidation (fluid or solid has replaced air containing lung or occupies pleural space)
- 26Percussion note findings over lung fields: What would hyper resonant lung sounds indicate?Hyperresonant – Emphysema, pneumothorax, asthma
- 27Percussion note findings over lung fields: What would tympanic lung indicate?Tympanic – large pneumothorax

- 30PERCUSSION anterior: (ladder technique)PERCUSSION
posterior:
(ladder technique)
- 31What is the purpose of the ascultation?- Assess air flow thru tracheobronchial tree
- Listening to breathing sounds
- Listening to adventitious (added) sounds - 32What should you then listen to if you hear abnormal breathing sounds?- If you hear abnormal breath sounds, you should then listen to spoken/whispered voice sounds as they are transmitted through the chest wall
- 33What are tracheal breath sounds?Sounds heard directly over trachea & neck
Very loud/high pitched
Expiratory/inspiratory component equal - 34What are bronchial breath sounds?Heard directly over a major bronchus
Loud/high pitched
Short silence between insp & exp with exp lasting longer - 35Where are Bronchovesicular breath sounds best heard?Best heard in 1st and 2nd ICS anteriorly and between scapula posteriorly
Medium pitch
Equal insp/exp - 36Where are vesicular breath sounds best heard?best Heard over lung fields
Soft low pitch
Inspiration last longer than expiration - 37What are types of adventitious sounds?- Rales
- wheezes/rhonchi
- stridor
- pleural friction rub
- mediastinal crunch - 38Adventitious Sounds: What are rales?Intermittent, nonmusical dots in time
Can be fine or coarse, dry or wet
Crackling noises caused by deflated, fluid filled small airways popping open with air
Can be heard with pneumonia, fibrosis, bronchitis - 39Adventitious Sounds: What do wheezes/rhonchi sound like? What do wheezes indicate? What do rhonchi indicate?- Musical continuous sounds
- Wheezes indicate narrowed bronchi (high-pitched)
- Rhonchi indicate secretions (low pitched, snot-like) - 40Adventitious Sounds: What does stridor sound like? What does it indicate?high pitched wheeze during inspiration that is louder at the neck; indicates upper airway obstruction
Note: if you listen to someones trachea it will sound louder than other areas, DANGEROUS! Impending respiratory failure, might be foreign body in trachea - 41Adventitious Sounds: What does Pleural Friction Rub sound like?“floor creaking noise” in one area;
2 pleural surfaces rubbing against each other (rubbing fingers against ear) - 42Adventitious Sounds: What does Mediastinal Crunch (Hamman’s sign) sound like?- precordial crackles caused by air between pleurae

3- whispered pectoriloquy - 44How do you test for Bronchophony? During bronchophony: What does a normal lung sound like? What does a bronchophony sound like?Ask patient to say “99” and listen with stethoscope
Normal: MUFFLED
Bronchophony: LOUD & CLEAR (indicated air-filled lung has become AIRLESS - 45How do you test for egophony? What is indicated if you hear EE instead of AY?Ask patient to say “EE” while listening with stethoscope
If you hear EE instead of AY & quality is nasal, indicates pneumonia or other consolidation - 46How do you test for Whispered Pectoriloquy? What does a normal whisper sound like and what does consolidation sound like?Ask patient to whisper “99” while listening with stethoscope
Normal: Barely audible
Consolidation: LOUD & CLEAR - 47What is respiratory excursion?purcussing diaphragm and estimating distance that diaphragm expands (assymetry)
- 48What is peak flow?- used to access obstruction
- pt. breathes as hard & fast as they can into meter, dial shows if pt has increased respiratory flow (i.e. seen in asthma) and then give them breathing treatment to see if peak flow number improves - 49Chronic Obstructive Pulmonary Disease (COPD)chronic bronchitis & emphysema
- 50What is chronic bronchitis? What is emphysema?Chronic bronchitis – excessive mucus production in bronchi

- 54What are the physical findings during percussion for COPD?hyperresonant
- 55What are the physical findings during auscultation for COPD? What are the physical findings during adventitious sounds?Auscultation: decreased breath sounds
Adventitious sounds – none; or crackles, wheezes and rhonchi - 56What is asthma?Hyper-reactivity of bronchial tree resulting in inflammation, hypersecretions and bronchoconstriction
No structural or permanent damage - 57Asthma can be asymptomatic with exacerbations or:Mild intermittent
Mild persistent
Moderate persistent
Severe persistent - 58What are some physical findings during an asthma attack? Are there any physical findings during a normal exam?Accessory muscles used to breathe
Resonant percussion note
Wheezes
Decreased peak flow
- not during attack: normal exam - 59What is a pneumothorax?Air leakage into the pleural space cause pressure gradient between space and lung
- 60What is a spontaneous pneumothorax?spontaneous rupture of bleb (bulla)

- 62What are the physical findings during a pneumothorax?Chest rise is asymmetrical
Hyperresonant percussion note over affected lung
decreased or absent:
Tactile fremitus
Breath sounds (over infected lung) - 63What is Pneumonia?- Inflammation of lung tissue caused by bacterial, viral or mechanical causes
- Alveoli fill with fluid or pus
- pneumonia can be lobar or diffuse - 64What are the physical findings during inspection for pneumonia?- Inspection: normal unless respiratory distress
- 65What are the physical findings during percussion for pneumonia?- Percussion: dull percussion note
- 66What are the physical findings during auscultation for pneumonia?- Auscultation: bronchial breath sounds, inspiratory rales
