Question: Answer:
What complications can arise from Atelectasis is common, which can lead to
thoracic or abdominal surgery? hypoxemia.


Question: Answer:
What is the purpose of lung To increase lung pressure by either decreasing
expansion therapy? external pressure (spontaneous deep breaths)
or increasing internal pressure (positive pressure
techniques like CPAP), enhancing the
transalveolar pressure gradient for alveolar
expansion.


Question: Answer:
What causes gas absorption It occurs when ventilation is blocked in part of
atelectasis? the lung or there is a major imbalance between
ventilation and blood flow, often due to

Question: Answer:

transalveolar pressure, often due to shallow
breathing which prevents alveoli from staying
open.


Question: Answer:
What is the difference between High V/Q ratios indicate areas of the lung with
high and low V/Q ratios? good ventilation but poor perfusion, while low
V/Q ratios indicate areas with poor ventilation
and good perfusion, leading to impaired oxygen
exchange.
