Analysis and applications of respiratory surface EMG:report of a round table meeting

Surface electromyography (sEMG) can be used to measure the electrical activity of the respiratory muscles. The possible applications of sEMG span from patients suffering from acute respiratory failure to patients receiving chronic home mechanical ventilation, to evaluate muscle function, titrate ventilatory support and guide treatment. However, sEMG is mainly used as a monitoring tool for research and its use in clinical practice is still limited-in part due to a lack of standardization and transparent reporting. During this round table meeting, recommendations on data acquisition, processing, interpretation, and potential clinical applications of respiratory sEMG were discussed. This paper informs the clinical researcher interested in respiratory muscle monitoring about the current state of the art on sEMG, knowledge gaps and potential future applications for patients with respiratory failure.</p

Droplets and outgrowths on high-Tc laser ablated thin films

YBa2Cu30x thin films have been grown on silicon, SrTi03 and Zr02 substrates using the pulsed laser deposition technique. Special attention has been paid to droplets and outgrowths which appear on the thin films during the growth process. The droplet density was studied as a function of the laser spot size, the laser energy and the target density. The number of droplets could be reduced to 1 per 100 μm2 for a 100 nm thick film, by ta1cing a large laser spot size and low energy density. The droplet density does not depend on the target density in the range from 80 to 94 % . The number of outgrowths could be reduced to 1 per 100 μm2 for a 100 nm thick film by reducing the deposition temperature or increasing the laser frequency. However, the critical temperature of these layers was reduced by 5 to 10 K. Using SAM no differences in composition between an outgrowth and the rest of the film could be detected

New type of wasted effort during neurally adjusted ventilatory assist: A case report

In patients with dynamic hyperinflation, such as patients with chronic obstructive pulmonary disease (COPD), development of intrinsic positive end-expiratory pressure (PEEPi) complicates ventilator triggering in conventional assisted ventilation modes, such as pressure support, and causes wasted efforts. The use of extrinsic PEEP (PEEPe) can counterbalance PEEPi and as such facilitate triggering. With neurally adjusted ventilatory assist (NAVA) the ventilator is triggered by an increase in diaphragm electrical activity and does not depend on generation of inspiratory flow. Numerous studies report the absence of ‘classical’ wasted efforts with NAVA. Therefore, the widespread assumption among physicians is that wasted efforts cannot occur with NAVA. We present a 58-year-old male with an acute exacerbation of COPD in which we identify a new type of wasted effort unique to NAVA. We show that during NAVA in the presence of PEEPi it is as important to perform titration of PEEPe as with conventional modes, in order to prevent wasted efforts
