Q

What is dyspnea? What causes it (broadly)?

A

Def: subjective experience of breathing discomfort; the sensation is holistic

  • Results from interaction (mismatch) of various efferent and afferent signals
  • May be respiratory, cardiovascular, or non-cardiac non-respiratory

Q

What are some specific causes of dyspnea?

A

(Recall: interaction/mismatch of various efferent and afferent signals)

  • Mechanical interference with ventilation
  • Weakness of respiratory pump
  • Increased respiratory drive
  • Wasted ventilation
  • Physiologic

Q

What qualifies as “massive” hemoptysis? What is the problem?

A

Massive = 500 mL in 24 hours (or 250 in 6 hrs)

  • 1 foam cup = 125 mL

Problem is not the blood loss, but rather the volume in the lung

24
Q

How does substernal thyroid goiter present?

Study These Flashcards
A

Wheezing that is worse when supine

25
**T/F:** lung tissue has extensive pain fibers
**False**; lung tissue has no pain fibers! (Pleura, however, has many)
26
In what conditions is chest pain typically felt?
- Pneumothorax - Pleuritic chest pain (worse with inspiration!) - Cardiac chest pain - Muscle strain
27
Important respiratory things to cover in the history?
- Family History - Occupational History (Important!) - Smoking history - Exposures
28
What parts of the physical exam inspection should be noted in regard to the respiratory system?
- **Color** (pallor, cherry-red, cyanosis) - **Smell of breath** - **Nails** (clubbing) - **Neck** - **Shape of chest** (barrel, thoracic kyphoscoliosis, pectus excavatum) - **Signs of respiratory distress**
29
What are some distinctive breath smells tied to medical conditions? - Foul - Ketone - Bitter almond
- Foul smelling sputum: anaerobic infection - Ketone/"rotten apple": diabetic ketoacidosis - Bitter almond: cyanide poisoning
30
What are signs up respiratory distress to be aware of upon inspection?
- Tachypnea - Intercostal retractions - Respiratory alternans (alternating pulse pressure with breathing) - Pursed lip breathing - Use of accessory muscles
31
How can tracheal position be abnormal? How does it respond to certain medical conditions (pneumothorax, effusion, collapse, mass)?
_Deviates:_ - Away from pneumothorax and effusion - Towards collapse May also be deviated by a mass (e.g. enlarged lymph nodes)
32
How can vocal fremitus clue you in to a certain disorder?
- Increased over areas of consolidation - Decreased/absent over areas of effusion or collapse
33
What may cause symmetrical reduction in chest expansion?
- Overinflated lungs (e.g. emphysema) - Stiff lungs (e.g. pulmonary fibrosis) - Ankylosing spondylitis
34
What may cause asymmetrical reduction in chest wall expansion?
_Reduced expansion:_ - Pulmonary consolidation - Collapse _Absent expansion:_ - Empyema - Pleural effusion

Vesicular breath sounds: - Duration: **insp \> exp** - Intensity of Expiration: **soft** - Pitch of Expiration: **low** - Normal location: **majority of both lungs** - Sounds like: **wind blowing through trees**
43
**Broncho-vesicular** breath sounds: - Duration - Intensity of Expiration - Pitch of Expiration - Normal location - Sounds like
Broncho-vesicular breath sounds: - Duration: **insp = exp** - Intensity of Expiration: **intermediate** - Pitch of Expiration: **intermediate** - Normal location: **ant 1-2 interspaces, between the scapula** - Sounds like: ---
44
**Bronchial** breath sounds: - Duration - Intensity of Expiration - Pitch of Expiration - Normal location - Sounds like
Bronchial breath sounds: - Duration: **exp \> insp** - Intensity of Expiration: **loud** - Pitch of Expiration: **high** - Normal location: **possibly over manubrium** - Sounds like: **air blowing through cardboard tube**
45
Characteristics of crackles? When are fine/coarse crackles heard?
Aka **rales** **- Discontinuous** **- Non-musical/brief** **Fine crackles:** soft, high pitched, very brief (fibrosis) **Coarse crackles**: louder, lower in pitch, brief (pneumonia, CHF)
46
Characteristics of wheezes and ronchi? When is each heard?
- Continuous - Musical prolonged **Wheezes**: higher pitch with hissing, shrill quality (narrowed airways like asthma, COPD, bronchitis) **Rhonchi**: lower pitch with snoring quality (secretions in large airways)
47
Characteristics of stridor?
Predominantly inspiratory; suggests partial obstruction of larynx or trachea
48
Characteristics of pleural rub?
Sound like crackles but more continuous in both phases and in small area
