Electrical impedance tomography (EIT) is a noninvasive imaging modality that allows continuous assessment of changes in regional bioimpedance different organs. One its most common biomedical applications monitoring ventilation distribution critically ill patients treated intensive care units. In this work, we put forward proof-of-principle study demonstrates how one can reconstruct synchronousl...

Typical disposable Ag/AgCl electrodes have potential drawbacks from a long-term measurement perspective. Particularly, they can cause an allergic reaction of the skin and can detach in case of sweating during physical activity or sleep. As they are disposable, the electrodes cannot be removed for cleaning. They must be connected to a device with separate cables, which adds to the wearer’s disco...

BACKGROUND Monitoring of respiratory function is important in the diagnosis and management of respiratory disease. The forced oscillation technique requires minimal patient cooperation and is ideal for the determination of respiratory function in young children. This study aimed to develop reference ranges and to document the repeatability in healthy young children using commercially available ...

INTRODUCTION Respiratory syncytial virus (RSV) lower respiratory tract disease is characterised by narrowing of the airways resulting in increased airway resistance, air-trapping and respiratory acidosis. These problems might be overcome using helium-oxygen gas mixture. However, the effect of mechanical ventilation with heliox in these patients is unclear. The objective of this prospective cros...

We propose a novel approach to optimizing the sensitivity of a single coil sensor based on a theoretical model derived from electromagnetic theory. The thorax is subject to variations in conductivity due to respiratory and cardiac activities and our electromagnetic sensor is designed to measure these changes. We derive a theoretical model for changes in impedance of a current carrying coil caus...
