Dielectric barrier discharge (DBD) excimer lamps emit vacuum-UV optical radiation. This work presents novel methods for efficiently operating DBDs with short, high-voltage pulses. Transformer-less systems utilising SiC power semiconductor switches are presented. Pulse frequencies of up to 3.1 MHz and peak inverter efficiencies of 92 % were achieved. The work encloses both mathematical backgrounds of pulsed resonant circuits and practical implementation of low-inductive power stages.

This book presents the state of the art in high-flow nasal cannula (HFNC), an oxygen therapy technique that has recently proven to be a very promising approach to supporting respiratory function in several medical fields. In the opening part of the book, readers will learn the differences between high-flow and low-flow techniques and gain an overview of HFNC’s technical aspects and physiological effects. The book subsequently describes the pathophysiological mechanisms involved in different respiratory diseases, analyzing how this technique positively impacts patients’ respiratory status. The authors highlight clinical applications of HFNC, both in adults and in children, in various clinical settings – e.g. intensive care and semi-intensive care unit, emergencies, rehabilitation etc. – and present tips, tricks and pitfalls, as well as up-to-date reports on technical issues. The book is intended for pneumologists, intensivists, anesthesiologists, ED doctors, rehabilitation therapists, internists and oncologists, as well as fellows and nurses in these fields.
