This phenomenon has clinical significance because, both in healthy and … Total dead space (also known as physiological dead space) is the sum of the anatomical dead space and the alveolar dead space. Benefits do accrue to a seemingly wasteful design for ventilation that includes dead space. 1. Carbon dioxide is retained, making a bicarbonate-buffered blood and interstitium possible. 2. Inspired air is brought to body temperature, increasing the affinity of hemoglobin for oxygen, impr…
Webb21 dec. 2016 · Anatomical dead space volume represents an amount of air that does not participate in gaseous exchange because it is retained in the respiratory tract, and can not reach vascularised alveoli. Generally an young adult breathes in 500ml of air, which is called tidal volume . 150ml of tidal volume occupies anatomical dead space. Answer link WebbThe physiological dead space is the anatomical dead space plus alveolar dead space. The anatomical dead space is the total volume of the conducting airways from the nose or mouth to the terminal bronchioles, and in ventilated infants includes the apparatus dead space (endotracheal tube and flow sensor).
