![]() ![]() Some apparatus dead space may actually reduce total dead space, as an ETT bypasses the majority of anatomical dead space of the patient (nasopharynx).ĭead space from the patient. Types of Dead Spaceĭead space from equipment, such as tubes ventilator circuitry. Glomerular Filtration and Tubular Functionĭead space is the proportion of minute ventilation which does not participate in gas exchange. Normal respiratory physiology is maintained by a VQ match, meaning a normal relationship between the amount of air entering the alveoli within the lungs (VENTILATION) and the amount of blood passing the alveoli within the pulmonary vasculature (PERFUSION). Anatomic dead space is the total volume of the conducting airways from the nose or mouth down to the level of the terminal bronchioles, and is about 150 ml on the average in humans. There are two different ways to define dead space- anatomic and physiologic. ![]() Alveolar dead space Physiologic dead space. Dead space is the portion of each tidal volume that does not take part in gas exchange. Functional Anatomy and Control of Blood Flow Anatomical dead space is the volume of air in the conducting airways that does not participate in gas exchange. ![]()
