WebJun 8, 2024 · 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 tissue. Dead spaces can severely impact breathing due to the reduction in surface area available for gas diffusion.
