BACKGROUND Inhaled perfluorohexan vapor has been shown to improve gas exchange and pulmonary mechanics in oleic acid- and ventilator-induced lung injury. However, in the clinical setting, lung injury frequently occurs in the context of systemic inflammation and consecutive lung injury, which may be induced experimentally by intravenous administration of endotoxin. The authors studied whether va...
Oral fluid (OF) is an important matrix for monitoring drugs. Smoking cannabis is common, but vaporization and edible consumption also are popular. OF pharmacokinetics are available for controlled smoked cannabis, but few data exist for vaporized and oral routes. Frequent and occasional cannabis smokers were recruited as participants for four dosing sessions including one active (6.9% Δ9 -tetrah...
Plasma environments constitute powerful tools in materials science due to their operation as thermal and chemical reactors. A microwave, atmospheric argon plasma driven by surface waves has been used for synthesizing carbon nanostructures by passing vaporized ethanol through the plasma. Graphene sheets and carbon nanoparticles have been selectively synthesized through the control of the outlet ...
A fluctuation-free mercury arc lamp for the pumping of a cw alexandrite laser is reported. Thermal insulation of a cathode of the lamp permits 4-kW fully vaporized direct-current operation. Fluctuations owing to the pool of liquid mercury in conventional lamp tubes is completely avoided. A 17-W, cw alexandrite laser pumped by the newly developed lamp is described.
BACKGROUND During mechanical ventilation effective conditioning of inspired air is important. In this respect, conventional humidifiers do not perform optimally. By design, a counter-flow-type humidifier should improve humidification and heating, but may increase resistance. METHODS We investigated mechanical impedance and work of breathing (using pressure-flow characteristics and additional ...
