Related terms: Artificial Respiration; Tidal Volume; High-Frequency Ventilation; Continuous Positive Airway Pressure; Respiratory Minute Volume; Breathing Rate; Perfusion Anatomical dead space is that portion of the airways (such as the mouth and trachea to the bronchioles) which conducts gas to the alveoli. In healthy lungs where the alveolar dead space is small, Fowler's method accurately measures the anatomic dead space by a nitrogen washout technique. •Anatomical dead space –Volume of conducting airways –Upper airways, larynx, trachea, bronchi and bronchioles –Does not include respiratory bronchioles and alveoli •Physiologic dead space (VDphys) –Total volume of the lungs that does not participate in gas exchange –Includes anatomic dead space plus a functional dead space in the alveoli What are the different types of dead space? Dead space is classified as ‘anatomical’, ‘alveolar’ or ‘physiological’: Anatomical dead space VDAnat is the volume of the upper airways and first 16 generations of the tracheobronchial tree, which form the conducting airways (see Chapters 6 and 7). 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. 2018-07-17 2015-06-01 Anatomical dead space occurs naturally in areas of the lungs that don’t come in contact with alveoli (like the trachea).

In normal subjects the volumes are very nearly the same. In some disease of the lungs the physiological dead space may amount to 1 to 2 litres producing great respiratory insufficiency.

Alveolar dead space describes ventilated lung normally contributing to gas exchange, but not doing so because of impaired perfusion. The ratio (Vd/Vt) of dead space volume (Vd) and the volume of ventilation to perfused alveoli (Vt) is normally 0.3. In general, is anatomical dead space or physiological dead space a larger volume? Physiological dead space will be larger since it is the sum of both the volume occupied by structures that cannot conduct gas exchange plus the volume of air that does not undergo gas exchange due to normal or pathological states of the lung. of the anatomical dead space, if all alveoli work approximately ideally (young healthy lungs).
