Webb8 juni 2024 · However, at times, there is a mismatch between the amount of air (ventilation, V) and the amount of blood (perfusion, Q) in the lungs. This is referred to as ventilation/perfusion (V/Q) mismatch. There are two types of V/Q mismatch that produce dead space. Dead space is characterized by regions of broken down or blocked lung … Webb29 aug. 2024 · The detection of right-to-left anatomical shunting is not always clinically straightforward.
