Bronchoaspiration results in local deterioration of lung function through direct damage and/or indirect systemic effects related to neurohumoral pathways. We distinguished these effects by selectively intubating the two main bronchi in pigs while a PEEP of 4 or 10cm H2O was maintained. Gastric juice was instilled only into the right lung. Lung mechanical(More)
—We consider the problem of joint power control, signal-to-noise-and-interference-ratio (SINR) target setting, mode selection and resource allocation for cellular network assisted device-to-device (D2D) communications. This problem is important for fourth generation systems, such as the release under study of the Long Term Evolution Advanced (LTE-A) system(More)
At the Technical University of Budapest within the scope of a project supported by the Hungarian Research Fund (OTKA, grant No. T029072) an experimental robot control system has been developed. Last year a new component, a six-axis force/torque sensor and the related control unit were added to the system, allowing to implement the hybrid position and force(More)
BACKGROUND Fluid replacement with blood products, colloids and crystalloids is associated with morbidity and mortality. Despite this, the consequences of fluid administration on airway and respiratory tissue properties are not fully understood. OBJECTIVE Comparison of respiratory effects of fluid replacement with autologous blood (Group B), colloid (HES(More)
BACKGROUND Several epidemiological and laboratory studies have evidenced the fact that atmospheric particulate matter (PM) increases the risk of respiratory morbidity. It is well known that the smallest fraction of PM (PM1 - particulate matter having a diameter below 1 μm) penetrates the deepest into the airways. The ratio of the different size fractions in(More)
The contribution of the hematocrit (Hct) of the blood in the pulmonary vasculature to the overall lung mechanics has not been characterized. We therefore set out to establish how changes of the Hct level in the pulmonary circulation affect the airway and lung tissue viscoelastic properties. The Hct level of the blood in an isolated perfused rat lung model(More)
BACKGROUND Capnography may provide useful non-invasive bedside information concerning heterogeneity in lung ventilation, ventilation-perfusion mismatching and metabolic status. Although the capnogram may be recorded by mainstream and sidestream techniques, the capnogram indices furnished by these approaches have not previously been compared systematically.(More)
BACKGROUND Although the mechanical status of the lungs affects the shape of the capnogram, the relations between the capnographic parameters and those reflecting the airway and lung tissue mechanics have not been established in mechanically ventilated patients. We, therefore, set out to characterize how the mechanical properties of the airways and lung(More)
