This can occur due to:Īlveoli are tiny air sacs in the lungs where gas exchange occurs. Alveolar Dead SpaceĪlveolar dead space is the volume of air that reaches the alveoli but does not participate in gas exchange due to a lack of perfusion. Note: Anatomical dead space is estimated to be approximately 1 mL/lb of ideal body weight.įor example, if a patient has an ideal body weight of 162 lbs, their anatomical dead space would be approximately 162 mL. The air that remains in this area that does not participate in gas exchange is the anatomical dead space. When you take a breath in, air first enters through the nose and then travels down the trachea into the bronchi. The conducting airways are made up of the nose, trachea, and bronchi. 2011 56(2):140–52.There are three primary types of dead space:Īnatomical dead space is the volume of air in the conducting airways that does not participate in gas exchange.
