Ventilator strategies addressing V/Q — Flashcards

Flashcard 1: What type of V/Q mismatch occurs due to airway obstruction? _____

Answer: Shunt (perfusion but no ventilation)

Flashcard 2: Rank the following variables for zone 3 of the lung: PA, Pa, and Pv _____

Answer: Pa > Pv > PA

Answer: Shunt

Flashcard 6: Rank the following variables for zone 2 of the lung: PA, Pa, and Pv _____

Answer: Pa > PA > Pv

Flashcard 7: The _____ ratio is the ratio of alveolar ventilation to pulmonary blood flow

Answer: ventilation/perfusion (V/Q)
