Open AccessTidal volume significantly affects oxygenation in healthy pigs during high-frequency oscillatory ventilation compared to conventional ventilation
The role of high-frequency oscillatory ventilation (HFOV) has long been debated. Numerous studies documented its benefits, whereas several more recent studies did not prove superiority of HFOV over protective ...

Breathing Experiments into the Simulated Avalanche Snow: Medical and Technical Issues of the Outdoor Breathing Trials
Avalanche burials represent one of the most dangerous risks associated with winter activities in the mountains. Asphyxiation occurs as a consequence of blocked airways; or, due to a severe hypoxia and hypercap...

Design and Demonstration of a Complex Neonatal Physiological Model for Testing of Novel Closed-Loop Inspired Oxygen Fraction Controllers
Recently published clinical trials document that manual control of oxygen fraction in the inspiratory gas in neonates is not prompt enough to react to the rapidly changing physiological status of a neonate. As...

Center of Ventilation—Methods of Calculation Using Electrical Impedance Tomography and the Influence of Image Segmentation
Electrical impedance tomography (EIT) is a promising non-invasive, radiation-free imaging modality. Using EIT-derived index Center of ventilation (CoV), ventral-to-dorsal shifts in distribution of lung ventila...

Design and Evaluation of a System Assuring Spontaneous Breathing in Patients Connected to a High-Frequency Oscillatory Ventilator
Patients connected to a high-frequency oscillatory ventilator should be paralysed or highly sedated so that the ventilator is able to work. The aim of the study is to design a special “Demand Flow System” allo...
