V/Q mismatch — Flashcards

_____ is ventilation of lung regions that are not perfused (V/Q = ∞)

The V/Q mismatch seen in pulmonary embolism can result in _____, which causes hyper-ventilation with consequent respiratory alkalosis

What is the major factor determining autoregulation of blood flow to the lungs? _____

In certain pathologic situations, the physiologic dead space may become greater than the anatomic dead space, suggesting a(n) _____ defect

When a person is standing, pulmonary blood flow is highest at the _____ of the lungs

In zone 1 (apex) of the lung, alveolar ventilation (V) is _____

In response to exercise, the V/Q ratio from apex to base becomes more _____ (even or uneven)

If there is a(n) _____ obstruction, the V/Q ratio = 0 (shunt)

What is the ideal V/Q ratio for adequate gas exchange? _____

What type of V/Q mismatch occurs due to pulmonary embolus? _____
