A. True.
B. True.
C. False. Hypoxic pulmonary vasoconstriction is a normal physiological response to match ventilation and perfusion in different parts of the lung. Abolition of this response leads to ventilation-perfusion (V/Q) mismatching and resulting hypoxia. Unfortunately, volatile agents do impair this response to a certain extent. This is one reason why the fraction of inspired oxygen is usually increased above 21 % during anaesthesia when volatile agents are used.
D. True.
E. True.
