Dissipated energy during protective mechanical ventilation

Introduction From literature we know that a cornerstone of the protective lung ventilation in Acute Respiratory Distress Syndrome (ARDS) patients [1] and during general anesthesia [2] is a low tidal volume. On the other hand, driving pressure seems to be the variable that best stratifies mortality risk [3]. Our hypothesis is that the combination of volume and pressure, that is the energy dissip...

Heliox Improves Carbon Dioxide Removal during Lung Protective Mechanical Ventilation

Introduction. Helium is a noble gas with low density and increased carbon dioxide (CO2) diffusion capacity. This allows lower driving pressures in mechanical ventilation and increased CO2 diffusion. We hypothesized that heliox facilitates ventilation in patients during lung-protective mechanical ventilation using low tidal volumes. Methods. This is an observational cohort substudy of a single a...

Heliox during mechanical ventilation.

The indications for heliox during mechanical ventilation are lower-airway obstruction, especially with hypercarbia; need to enhance aerosol delivery to lung periphery; and need to facilitate weaning from mechanical ventilation. Certain ventilators perform relatively well with heliox and are not substantially affected by it. It is preferable to connect the heliox to the air inlet of the ventilat...

Protective mechanical ventilation, why use it?

BACKGROUND AND OBJECTIVES Mechanical ventilation (MV) strategies have been modified over the last decades with a tendency for increasingly lower tidal volumes (VT). However, in patients without acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) the use of high VTs is still very common. Retrospective studies suggest that this practice can be related to mechanical ventilation-a...

Intraoperative protective mechanical ventilation: what is new?

Postoperative pulmonary complications are an important cause of hospital morbidity and mortality and are known to be associated with longer hospital stays and higher long-term mortality rates.(1) Thus, it is imperative to recognize early risk factors for the development of postoperative pulmonary complications (PPC) and to focus on the adoption of measures to prevent them from occurring.(1) Amo...
