( physiology ) The sum of the parallel and the serial dead spaces.Alveolar dead space Physiologic dead space. ( physiology ) The sum of the anatomic plus the alveolar dead spaces. Anatomical dead space is the volume of air in the conducting airways that does not participate in gas exchange.Because this is a functional measurement, the volume is called the physiologic dead space. Dead Space: Liberation is a graphic novel in the Dead Space series, written by Ian Edgington and Christopher Shy. Lippincott Williams & Wilkins Ninth edition.īohr's method measures the volume of the lung which does not eliminate CO 2. Functional dead space: aka, alveolar dead space comprises alveoli where gas exchange does not occur (i.e., non-perfused alveoli). Learn and reinforce your understanding of Anatomic and physiologic dead space. West, Respiratory Physiology: The Essentials. Anatomic and physiologic dead space Videos, Flashcards, High Yield Notes, & Practice Questions. ( physiology ) That volume of air in the lung that does not eliminate carbon dioxide, as defined functionally by the Bohr equation.( physiology ) That volume of air in the lung which does not partake in gas exchange.Throughout this paper, the term physiological dead space will be used to refer to the volume of the conducting airway down to the location at which a large change in gas composition occurs. This definition became inadequate once the alveolar dead space was described. ( obsolete ) The volume of the conducting airways of the lung.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.Physiologic dead space ( countable and uncountable, plural physiologic dead spaces) An elevated physiological dead space, calculated from measurements of arterial CO 2 and mixed expired CO 2, has proven to be a useful clinical marker of prognosis both for patients with acute respiratory distress syndrome and for patients with severe heart failure. 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
