Solution

The false statement is e. "Haemoglobin saturation will significantly decrease with even small decreases in alveolar pO2".

This is not true because the oxygen-hemoglobin dissociation curve is sigmoidal, not linear. This means that, within a certain range of partial pressures of oxygen (pO2), a decrease in alveolar pO2 will not significantly decrease hemoglobin saturation. Hemoglobin remains relatively saturated with oxygen even when the pO2 decreases, until a critical point is reached. This property allows hemoglobin to deliver oxygen to tissues even under conditions of lower oxygen availability.
