27
Q

What does pleural effusion create?

A

Restrictive lung defect, V/Q mismatch, and increase work of breathing

28
Q

What are signs of pleural effusion?

A

Decreased breath sounds

Decreased chest expansion

Pleural rub (early)

29
Q

What can result in severe cases of pleural effusion?

A

Mediastinal shift

30
Q

What is transudative pleural effusion?

A

Non infectious, results from mechanical factors influenced by rate of formation of pleural fluid

31
Q

What occurs in transudative pleural effusion?

A

Heart failure

Pulmonary embolism

Decrease lymphatic drainage

Decrease osmotic pressure

32
Q

What is exudative pleural effusion?

A

Caused by infection (pneumonia, malignancies, or tuberculosis)

33
Q

What type of cough is in transudative pleural effusion?

A

Non productive

34
Q

What type of cough is in exudative pleural effusion?

A

Productive cough

35
Q

What is the most common bones fractured in the chest due to trauma?

A

Ribs 4-10

36
Q

What is indicated if there is an upper rib fracture (ribs 1-3)?

A

High energy trauma (hardest to break)

37
Q

What is at an increased risk associated with lower rib fractures?

A

Intra abdominal injury

38
Q

What often results in an unstable chest wall?

A

Fractures in two locations on the same rib of 3 or more adjacent ribs

39
Q

What happens in flail chest?

A

Chest wall falls in during inspiration

Chest wall falls out during expiration

40
Q

What is at risk with flail chest?

A

Lacerated organs (kidney, liver, lungs) and possible respiratory failure

41
Q

What is pneumothorax?

A

Air or blood in the pleural space due to a breach in the parietal or visceral pleura

42
Q

What happens in pneumothorax?

A

Ipsilateral lung collapses causing hypoxia

43
Q

What does continued pressure increase in pneumothorax lead to?

A

Mediastinum shift toward contralateral lung and compresses it worsening the hypoxia

44
Q

What are symptoms of early pneumothorax?

A

Dyspnea, sudden sharp pain, tachycardia, decrease breath sounds and chest expansion

45
Q

What are the symptoms of late pneumothorax?

A

Decreased BP and tracheal shift

46
Q

What is primary pneumothorax?

A

Spontaneous occurrence with no underlying lung disease (more common in young tall thin males)

47
Q

What is secondary pneumothorax?

A

Associated with underlying lung disease like COPD

48
Q

What is iatrogenic pneumothorax?

A

Due to diagnostic or medical procedure

49
Q

What is traumatic pneumothorax?

A

Results from penetrating or non penetrating chest trauma

50
Q

What occurs in tension pneumothorax?

A

One way valve forms allowing air into pleural space but not out
(Mediastinal shift away from affected lung) (medical emergency)

51
Q

What is the third most common cause of death in hospitalized patients?

A

Pulmonary embolism

52
Q

Who does pulmonary embolism usually occur in?

A
