Physiology of One-Lung Ventilation
2021Abstract Ventilation and perfusion are matched under physiologic conditions for optimal gas exchange and oxygenation. Ventilation involves the entry and exit of air from the lungs, while perfusion involves the flow of blood through alveolar pulmonary capillaries.

[Intraoperative Ventilation Approaches to One-lung Ventilation].
Anasthesiologie, Intensivmedizin, Notfallmedizin, Schmerztherapie : AINS, 2021The management of thoracic surgery patients is challenging to the anesthetist, since one-lung ventilation (OLV) includes at least two major conditions: sufficient oxygenation and lung protection. The first is mainly because the ventilation of one lung is stopped while perfusion to that lung continues; the latter is related to the fact that the whole ...

Physiology of One-Lung Ventilation
Seminars in Cardiothoracic and Vascular Anesthesia, 1997The understanding of the physiology and management of one-lung ventilation (OLV) has advanced over the last two decades. OLV induces an obligatory shunt through the nonventilated lung that causes varying degrees of arterial hypoxemia. Shunt may also occur in the venti lated lung.

Paediatric one lung ventilation in the prone position
Pediatric Anesthesia, 1997Pulmonary lobectomy in the presence of infected secretions requires isolation of the affected lung to prevent soiling of the healthy lung. In young children this is usually accomplished using a Fogarty embolectomy catheter. We report the successful combination of a Fogarty catheter, a tracheal tube and the prone position, which provided adequate ...

Ventilatory management of one-lung ventilation.
Minerva anestesiologica, 2011Hypoxemia is considered to be the most important challenge during one-lung ventilation (OLV). Recent studies, however, have shown that one-lung ventilation can involve some lung damage and can therefore be per se a cause of hypoxemia. OLV can be associated to an injury: but the techniques used to improve oxygenation may also damage the lung.

Troubleshooting One-Lung Ventilation
2019Despite more reliable methods to ensure lung isolation, hypoxia during one-lung ventilation (OLV) can still be a challenge for the anesthesiologist. While a true lower acceptable limit of saturation has not been defined, and is likely different for different patients, cerebral oxygenation does fall significantly during thoracic anesthesia cases, and ...

Physiology of One-Lung Ventilation
2011Published estimates of the incidence of hypoxemia during one-lung ventilation (OLV) have decreased from 25% in the 1970s to currently less than 10% (1 2). Technical improvements (fiberoptic bronchoscopy, DLT design, etc.) account for some of this progress (Chapter 8). Improved understanding of the physiology of OLV has also contributed importantly and
