Emphysema The major mechanism of air flow limitation is loss of ?
|
Elastic recoil.
|
|
|
Loss of Elastic recoil does what? a)Reduces volume of air that can be expired. b) Reduces volume of air that can be inhaled. c) Increased volume of air that can be expired. d)Increased volume of air that can be inhaled.
|
A
|
|
|
why does air become trapped in the lungs?
|
Because loss of elastic recoil.
|

emphysema or CB? obstruction results form changes in lung tissues rather than
|
mucus production and inflammation

normal ventilation, but not perfused. a) dead space b) shunt 3) silent.
|
a) dead space
|

c) silent
|
|
|
Frequent infection complicated by bronchospasms w/ dyspnea and productive cough. Initially affects larger bronchi but eventually all become narrowed. Expiratory airway obstruction traps gas in distal portion of lung which leads to v/q mismatch and hypoxemia occurs. hypoventilation and hypercapnia.

atelectasis, asthma, pulmonary edema, pneumonia have which? a) shunt-low v/q b) dead space-high v/q c) silent- absence of ventilation and perfusion.
|
a)shunt
|
|
|
pulmonary embolism has which? a) shunt-low v/q b) dead space-high v/q c) silent- absence of ventilation and perfusion.
|
b) dead space

nosocomial pneumonia can be caused by all but which: a) staphylococcus b) klebsiella pneumoniae c) escherichia coli d) pneumoycystic jiroveci
|
d
|
|
|
reduced oxygenation of blood (aka reduced (PaO2) is a) hypoxia b) hypoxemia c) hypocapnia d) hypercapnia
|
