Does perfluorocarbon deoxygenate during partial liquid ventilation?
Perfluorocarbons accumulate in the dependent regions of the lungs, which may result in regional hypoxia if ventilation with oxygen is insufficient to oxygenate the dependent perfluorocarbon-filled alveoli. In this issue of Critical Care, Max et al present data that demonstrate a decrease in arterial oxygen tension (PaO2) at 30 min compared to that observed at 5 min after administration of FC 32...
متن کاملModeling Alveolar Gas Transport during Liquid Ventilation
Introduction During gas ventilation, gas transport within the alveolar sac is dominated by diffusion. In liquid ventilation, perfluorocarbon (PFC) introduced into the alveolar space acts as a diffusion barrier to gas transport since the diffusivities of oxygen and carbon dioxide in this medium are four orders of magnitude lower than in air. Therefore convection in the PFC layer resulting from t...

متن کاملTotal and Partial Liquid Ventilation Using Perfluorocarbons
Introduction The possibilities of using liquid instead of air in the exchange of gases have always fascinated researchers. The first studied liquid was saline solution which appeared to be unsuitable for transporting gases in normobaria. Its capacity to dissolve oxygen is low, and its viscosity and density are high as compared with air. Moreover, the introduction of saline into the lung can rem...
متن کاملSurfactant replacement increases compliance in premature lamb lungs during partial liquid ventilation in situ.
Treatments available to improve compliance in surfactant-deficient states include exogenous surfactant (ES) and either partial (PLV) or total liquid ventilation (TLV) with perfluorochemical (PFC). Because of the additional air-lung and air-PFC interfaces introduced during PLV compared with TLV, we hypothesized that compliance would be worse during PLV than during TLV. Because surfactant is able...
