Respiratory dead-space is often increased in lung disease. This study evaluates the effects of increased alveolar dead-space (VDalv), pulmonary shunt, and

The anatomic dead space is the gas volume contained within the conducting airways. The normal value is in the range of 130 to 180 mL and depends on the size and posture of the subject. The value increases slightly with large inspirations because the radial traction exerted on the bronchi by the surrounding lung parenchyma increases their size. 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).

Anatomical dead space is represented by the volume of air that fills the conducting zone of respiration made up by the nose, trachea, and bronchi. This volume is considered to be 30% of normal tidal volume (500 mL); therefore, the value of anatomic dead space is 150 mL.

The normal value is in the range of 130 to 180 mL and depends on the size and posture of the subject. The value increases slightly with large inspirations because the radial traction exerted on the bronchi by the surrounding lung parenchyma increases their size. Physiologic or total dead space is equal to anatomic plus alveolar dead space which is the volume of air in the respiratory zone that does not take part in gas exchange. The respiratory zone is comprised of respiratory bronchioles, alveolar duct, alveolar sac, and alveoli. In a healthy adult alveolar dead space can be considered negligible. The anatomic dead space is the gas volume contained within the conducting airways. The normal value is in the range of 130 to 180 mL and depends on the size and posture of the subject.

Anatomical dead space is that portion of the airways (such as the mouth and trachea to the bronchioles) which conducts gas to the alveoli.

Anatomical dead space is the volume of gas in the conducting airways, and alveolar dead space is the volume of gas which ventilates poorly perfused alveoli. The contribution of shunt can increase the arterial CO2 and give the appearance of increased dead space.

Objectives. To compare the anatomical (V D‐Ana) and alveolar dead space (V D‐Alv) in term and prematurely born infants and identify the clinical determinants of those indices.. Working Hypothesis. V D‐Ana and V D‐Alv will be higher in prematurely born compared to term born infants.. Study Design. Retrospective analysis of data collected at King's College Hospital NHS Foundation Trust

Anatomical dead space is that portion of the airways (such as the mouth and trachea to the bronchioles) which conducts gas to the alveoli. No gas exchange is possible in these spaces.
