CHAPTER 11 EGAN’S FINAL PAPER 2026
COMPLETE QUESTIONS AND ANSWERS
◉ when/where do the lungs and chest wall recoil against each
other? Answer: In the intact thorax
◉ What determines the resting volume of the lungs? Answer: The
point at which the lung and chest wall balance determines the
resting volumes of the lungs or frc.
◉ What is the relationship between chest wall expansion and lung
contraction? Answer: The chest wall expansion and lung contraction
are offset.
◉ what is partially responsible for the subatmospheric pressure in
the intrapleural space? Answer: The opposing forces between the
chest wall and lungs
◉ Lung compliance in healthy adults? Answer: Normal is 0.2 L/cm
H2O
◉ Tissue viscous resistance Answer: frictional forces during
displacement of lungs, ribs, diaphragm, and abdominal organs.
, ◉ Formula for resistance Answer: the change in pressure over the
change in flow.
R = Δ P/ Δ V
◉ Formula for work: Answer: work= force X distance
◉ Average O2 in healthy adults is... Answer: less than 5% of 02
consumption
◉ How many CC's of O2 /min do healthy individuals consume?
Answer: 250 cc O2/minute
◉ VE Answer: minute ventilation
◉ minute ventilation Answer: The total volume moving in and out of
the lungs per minute.
◉ Formula for minute ventilation: Answer: (RR or FB) Respiratory
Rate x (VT) Tidal Volume
◉ Alveolar ventilation (VA) Answer: Volume of fresh gas reaching
the alveoli
