Despite all these issues anatomical dead space remains an important concept and is an important factor in the ventilation of the lung. References: [1] Astrom E, Niklason L, Drefeldt B, Bajc M, Jonson B. Partitioning of dead space – a method and reference values in the awake human.

"Anatomical dead space is the portion of dead space which is external to the alveoli, consisting of mainly conducting airways, and represented by Phase I and half of Phase II in the single-breath nitrogen washout test" In some disease of the lungs the physiological dead space may amount to 1 to 2 litres producing great respiratory insufficiency. The normal ratio of dead space to tidal volume is in the range 0.2 to 0.35 during breathing at rest. This ratio increases with age but decreases on exercise. Anatomical dead space occurs naturally in areas of the lungs that don’t come in contact with alveoli (like the trachea). In these spaces, the lungs are ventilated and receiving enough air, but blood is not being oxygenated in that space because the air is not reaching perfused areas. An example of an anatomical shunt is the effect of gravity on the lungs. Anatomical dead space, or anatomical shunt, arises from an anatomical failure, while physiological dead space, or physiological shunt, arises from a functional impairment of the lung or arteries.

7. Drugs / Anes: increase dead space; due to bronchodilation 8. Lung disease (emphysema increase anatomical dead space; exicision of lung reduce dead space) 9. Endotracheal intubation; reduce anatomical dead space by 50% (but there is addition volume of the circuit) 10. Position of Jaw and neck; increase with Jaw protrusion in non -intubated people

a.ANATOMIC DEAD SPACE: Volume of the conducting airways, approximately 150 ml. b.PHYSIOLOGIC DEAD SPACE: The volume of the lung that does not participate in gas exchange.In normal lungs, is equal to the anatomic dead space (150 ml). May increase in several lung diseases.

Cysticfibrosis. Can block the trachea with mucus. Cystic fibrosis (also known as CF, mucovoidosis, The Alveoli have formed blebs (Blebs are abnormal vacuoles in the lungs which may range from about 3 mm to several centimeters in size. The anatomic dead space fills with inspired air at the end of each inspiration, but this air is exhaled unchanged. Additionally, what is the relationship between anatomical and alveolar dead space? Which value is likely to increase during lung pathology? Anatomical dead space is the space in the conducting respiratory passageways.

2019-11-07 · Anatomical dead space is the volume of air that is in the conducting zone of the lung. Physiological dead space is the combination of anatomical dead space plus alveolar dead space. Alveolar dead space is the volume of air that fills the gas exchanging regions of the lung but does not participate in gas exchange. Anatomic dead space is the total volume of the conducting airways from the nose or mouth down to the level of the terminal bronchioles, and is about 150 ml on the average in humans. The anatomic dead space fills with inspired air at the end of each inspiration, but this air is exhaled unchanged. b.PHYSIOLOGIC DEAD SPACE: The volume of the lung that does not participate in gas exchange.In normal lungs, is equal to the anatomic dead space (150 ml). May increase in several lung diseases.

Study Design Physiologic or total dead space is the sum of anatomic dead space and alveolar dead space. 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. Anatomical dead space is increased by increasing lung volume and alveolar dead space is increased because of hypotension produced by IPPV and PEEP (compression of venules in alveolar septae and interstitial tissue because of dilated alveoli by PEEP and IPPV leads to decreased venous return and compression of small arteries lead to decrease in pulmonary blood flow.
