Finally, we discuss the importance of ventilation-perfusion matching in the acute respiratory distress syndrome (ARDS) as well as the impact of prone positioning, positive airway pressure, and mechanical ventilation. In this chapter, we introduce the theoretical basis of gas exchange in the lung, including quantification of ventilation-perfusion \( \left( \) relationships in important ways. 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.The effective and efficient transfer of oxygen and carbon dioxide between the lung and bloodstream depends on close matching of ventilation and perfusion. 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. Functional Anatomy and Control of Blood Flow
