![]() There are three types of dead spaces: anatomic, alveolar, and physiologic. Physiological dead space can be calculated using Bohrs equation: Vd/Vt (PaCO2PeCO2)/PaCO2. 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. This portion of gas is referred to as deadspace ventilation. ![]() 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. ![]() VDBEBohrEnghoff dead-space calculated by.

Anatomic dead space is the volume of gas within the conducting zone (as opposed to the transitional and respiratory zones) and includes the trachea, bronchus, bronchioles, and terminal bronchioles it is approximately 2 mL/kg in the upright position. The meaning of ANATOMICAL DEAD SPACE is the dead space in that portion of the respiratory system which is external to the alveoli and includes the air-conveying ducts from the nostrils to the terminal bronchioles.
