What characterizes obstructive pulmonary flow?
|
Decreased expiratory flow from increased airway resistance, causing pulmonary inflation.
|
|
What are the five obstructive pulmonary diseases?
|
Emphysema
Chronic Bronchitis Asthma Bronchiectasis Cystic fibrosis |
|
What characterizes restrictive lung diseases?
|
Decreased inspiratory flow from decreased lung compliance. Lungs are difficult to fill with air.
|
|
What is the single restrictive lung disease she talked about?
|
Pulmonary fibrosis.
|
|
What characterizes consolidative lung diseases?
|
Replacement of alveolar air with fluid/collapsed alveoli. Decreases air/fluid ratio of lung tissue.

|
Name three common causes for lung consolidation.
|
Alveolar pneumonia with pus and cellular debris.
Left ventricular failure with leaking plasma. Atelectasis. |
|
What characterizes atelectasis?
|
Segment of lung collapses. Water density is increased, air/water ratio decreases.
|
|
During atelectasis, do the visceral and parietal pleura separate from each other?
|
Nope.
|
|
What causes atelectasis?
|
BLockage of air from entering alveoli. Air reabsorbs into vasculature and segments of the lung collapse.
|
|
What characterizes pneumothorax?
|
Air pressure enters pleural space, lung collapses, chest wall springs outwards.
|
|
Do the visceral and parietal layers of the pleura separate during pneumothorax?
|
Yes.
|
|
Describe a tension pneumothorax.
|
Air drawn into the pleural space cannot escape--pressure becomes higher.
Rapidly grows fatal as great vessels, heart, and opposite lung are compressed. Obstructive shock. |
|
Will the trachea move to the same side, or the opposite side, as the lung affected by tension pneumothorax?
|
Opposite side.
|
|
Describe pleural effusion.
|
Accumulation of fluid in pleural space. This fluid moves toward gravity-dependent regions and compresses underlying lungs.
|
|
In pleural effusion, the fluid that accumulates can either be protein poor, or protein rich. What diseases do these characterize, respectively?
|
Protein poor--congestive heart failure.
Protein rich--cancer. |
|
Which side is the trachea pulled to in atelectasis?
|
To the affected side.

|
Which side is the trachea pulled to in pleural effusion?
|
Away from the affected side.

|
Over 600 mls of blood in a 24 hour period.
|
|
What are the most common causes of hemoptysis?
|
Acute bronchitis, or other disorders involving airways, vasculature, or lung parenchyma. WHich is a supremely vague answer. Can also be caused by eroding aortic aneurisms in the arch.
|
|
Describe pleuritic pain. What differentiates it from an MI?
|
It is sharp or dull, and increases in intensoty with deep breathing, coughing, movement (unlike MI). It is localized but may radiate.
|
|
What is the most common cause of chest pain?
|
Costrochondritis.
|
|
Name three non-thoracic findings that may indicate lung disease.
|
Clubbing, Periosteal inflammation in the distal shaft of the long bones, and hypertrophic osteoarthropathy (HOA).
|
|
Most clubbing results from which two types of diseases?
|
Neoplastic/inflammatory lung disease. Ugh, such a vague question.
|
|
Tachyapnea in hospitalized patients is a bad prognostic factor and may indicate:
|
The presence of underlying cardiopulmonary disease--may portend imminent cardiopulmonary arrest.
|
|
Tachyapnea may be the first physical indication of:
|
Pneumonia, heart failure.
|
|
Bradypnea should prompt an evaluation for:
|
Hypothyroidism.
|
|
Chest ratio of anterioposterior diameter to lateral diameter is usually:
|
0.70 to 0.75, increasing to 0.90 in the elderly.
|
|
Name three curvatures of the spine that may inhibit breathing.
|
Kyphoscoliosis, pectus excavatum, pectus carinatum.
|
|
Describe flail chest.
|
One/both sides of chest move paradoxically inward during inspiration. Develops following multiple rib fractures.
|
|
Describe respiratory/abdominal paradox.
|
Retraction of the abdominal wall during inspiration--indicates bilateral diaphragmatic weakness/paralysis.

|
Decrease.
|
|
What expansive chest measurement is considered abnormal? What does it indicate disease-wise?
|
Anything less than 1 inch is abnormal. It is consistant with emphysema and/or restrictive lung disease.
|
|
Describe a vocal tactile fremitus (VTF)
|
Sound transmitted from teh larynx, causes a thrill on the suface of the chest that can be detected on palpation.
|
|
Asymmetric VTF is abnormal--describe the one exception and where it is located.
|
VTF over the right upper lobe is often great in intensity, because the trachea is closer to the apex of the right lung than the left.

|
|
Airway obstruction by mucous does what to VTF?

|
Increases air/water ratio, which decreases VTF.
|
|
When the air/water ratio goes down, VTF intensity...
|
Increases
|
|
Name several causes of lung consolidation.
|
Alveolar edema, alveolar pneumonia, alveolar hemorrhage, alveolar fibrosis.
|
|
Lung consolidation (barring atelectasis) causes VTF intensity to...
