chronic condition
49
pain is caused by pulmonary disorders that originates in the
pleurae, airways, or chest wall
50
what are the causes of pain

- infection and inflammation of the trachea or bronchi
- excessive coughing
51

54
Hypoxemia

56
causes of hypoxemia
- poor oxygen delivery to alveoli
- poor movement of oxygen from alveoli to blood
- perfusion of pulmonary capillaries
57
poor movement of oxygen from the alveoli to the blood is called
V/Q mismatch
58
V/Q mismatch happens when
part of your lung:
- receives oxygen without blood flow
or
- have blood flow without oxygen
59
V/Q mismatch refers to
abnormal distribution of ventilation and perfusion
60
Shunting
blood is moving through the lung but no ventilation
61
shunting example
when the alveoli fills with fluid, causing part of the lung to be unventilated although they are perfused
62
dead space
air is moving into the alveoli; no blood is moving by the lungs
63
dead space example
pulmonary embolism
64
alveolocapillary membrane is impaired
oxygen is there, circulation is there, but gas cannot be exchanged due to membrane impairment
65
alveolocapillary membrane is impaired example
pulmonary edema or fibrosis
66
signs and symptoms of VQ mismatch
aerobic metabolsim stops (increase in serum lactic acid, increased acid production leads to metabolic acidosis)
67
VQ mismatch can lead to
metabolic acidosis
68
acute respiratory failure
inadequate gas exchange
PaO2 <60 or high PCO2 >50
Ph <7.25
69

75
pukmonary contusion
bleeding into the pleural cavity, can cause poor inflation of lungs hypoventilation with atelectasis
