D)none of the above answers are correct

Question

Quizplus · Accepted Answer

A V/Q ratio of 0.64 indicates that blood flow is higher than ventilation in this region of the lung, which can lead to impaired gas exchange. An ideal V/Q ratio for optimal gas exchange is 1.0, where ventilation and blood flow are matched. A V/Q ratio less than 1.0 indicates that ventilation is higher than blood flow in that region, while a V/Q ratio greater than 1.0 indicates that blood flow is higher than ventilation.
