Dead space in acute respiratory distress syndrome [PDF]
Annals of Translational Medicine, 2018 Dead space is the portion of each tidal volume that does not take part in gas exchange and represents a good global index of the efficiency of the lung function. Dead space is not routinely measured in critical care practice, because the difficulties in in interpreting capnograms and the different methods of calculations.

MEASUREMENT OF LUNG DEAD SPACE VOLUME BY CAPNOVOLUMETRY
Паёми Сино, 2020 The article provides information on the lung dead space – a part of the respiratory volume that does not participate in gas exchange. The anatomical and alveolar dead spaces jointly together form the physiological dead space.

Role of Dead Space in the Development and Diagnosis of Respiratory Failure [PDF]
Общая реаниматология, 2009 The volumes of the dead space (anatomic and alveolar) play an important role in the physiology of external respiration and information on these volumes makes the diagnosis of different respiratory disorders easier.

Critical Care, 2023 Cumulative evidence has demonstrated that the ventilatory ratio closely correlates with mortality in acute respiratory distress syndrome (ARDS), and a primary feature in coronavirus disease 2019 (COVID-19)-ARDS is increased dead space that has been ...

Estimated dead space fraction and the ventilatory ratio are associated with mortality in early ARDS [PDF]
Annals of Intensive Care, 2019 Background Indirect indices for measuring impaired ventilation, such as the estimated dead space fraction and the ventilatory ratio, have been shown to be independently associated with an increased risk of mortality.

Unanesthetized dogs with increased respiratory dead space
Journal of Applied Physiology, 1960 A method is described for maintaining a permanent tracheostomy in dogs. This animal preparation has been used to study the effects of artificially increased respiratory dead space. Trained dogs with tracheostomies have made possible measurements of ventilation without anesthesia.

Relation between respiratory valve dead space and tidal volume
Journal of Applied Physiology, 1980 We measured the "effective" dead space of five commonly used respiratory valves: Hans Rudolph valve, two-way J valve, triple-J valve, and modified Otis-McKerrow valves without and with vane. The dead space was measured using a technique that mimicked the operation of valves during ordinary laboratory procedures.

Tracheostomy and respiratory dead space in emphysema
Journal of Applied Physiology, 1964 Acute experimentation to judge the effects of reduction of dead space with tracheostomy breathing was performed on four subjects with lower airway obstruction (bronchitis and emphysema) and on two subjects with upper airway obstruction (carcinoma of the larynx and tracheal stenosis).

Impact of Training with Additional Respiratory Dead Space on Spirometry and Exercise Respiratory Pattern in Cyclists [PDF]
Central European Journal of Sport Sciences and Medicine, 2015 The aim of our 10-week-long experiment was to investigate the impact of training with additional dead space (DS) on spirometry and exercise respiration. Respiratory muscle training is applied to the development exercise capacity.
