In a healthy individual, so the anatomic dead space is------than the physiological dead space.?1/28/2024 Effectively, 1/3 of a TV of inhaled air is rebreathed due to dead space. Anatomic, and therefore physiological, dead space normally is estimated at 2mL/kg of body weight and comprises 1/3 of the TV in a healthy adult patient it is even higher in pediatric patients. 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. Alveolar dead space typically is negligible in a healthy individual. 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. Physiological Dead Space ( Total Dead Space ) is the portion of a tidal volume that does not participate in gas exchange because it either remains in the conducting airways (Anatomic Dead Space) or does not get in contact with blood flowing through the pulmonary capillaries (Alveolar Dead Space). Functional Anatomy and Control of Blood Flow The official definition of anatomic dead space is that it is that part of the inhaled volume that remains in the airways at the end of inhalation and does not participate in gas exchange.
