OBJECTIVE Ventilator-induced lung injury is a risk in patients requiring elevated ventilatory support pressures. We hypothesized that thermal stress modulates the development of ventilator-induced lung injury. DESIGN Experimental study. SETTING University laboratory. SUBJECTS Anesthetized rabbits. INTERVENTIONS Two experimental studies were designed(More)
Sags are segments of the road where there is a significant change in gradient from downhill to uphill in a short distance. Empirically, it has been observed that drivers do not compensate adequately for the changing grade resistance force at sags, which limits vehicle acceleration. As a consequence, congestion forms at sags. This paper proposes and compares(More)
So-called vehicle dynamics (or controllability and stability) refer to the "running, cornering and stopping" of automobiles, which are the most important and basic performance of automobiles. Therefore, many studies have been undertaken from several points of view all over the world. In this paper, our former studies, which focused on the analysis and(More)
Skin incision before percutaneous central venous catheterization may cause serious hemorrhage and/or skin cicatrization. To minimize these adverse effects, we improved the shape of a dilator and coated it with lubricant to reduce insertion load. We selected three types of dilators from different manufacturers. Each brand was widely available on the market(More)
Electrocardiographic changes with myocardial ischemia include ST segment and T wave alterations. In this report, we present a case in which the ST segment and T wave changed synchronously with respiration during coronary artery bypass grafting (CABG) surgery. There has been no report on changes of ST segment morphology along with respiration, the etiology(More)
Freeway capacity decreases at sags due to local changes in car-following behavior. Consequently, sags are often bottlenecks in freeway networks. This article presents a microscopic traffic model that reproduces traffic flow dynamics at sags. The traffic model includes a new car-following model that takes into account the influence of freeway gradient on(More)
We conducted a sensory evaluation test to demonstrate the difference in palatability between Krestin and Carbocrin (generic drugs). In addition,we analyzed the odorous components and endotoxin contents of the two products to clarify the difference in physicochemical properties. In the sensory evaluation test, questions were asked on the odor, taste, feeling(More)
In pediatric cardiac anesthesia, we usually use high FIo2 to avoid hypoxia due to surgical and/or anesthetic mainpulation. However, it is well known that high FIo2 increases the pulmonary blood flow because of inhibition of hypoxic pulmonary vasoconstrictionl-3 • Thus, theoretically, ventilation with higher FIo2 might be disadvantageous to the patients who(More)
To the Editor: Takei et al. [1] reported that out-of-hospital intubation by paramedics was associated with increased incidence of sustained return of spontaneous circulation comparing with bag-valve-mask ventilation and alternative airway techniques. Their findings are consistent with previous studies, which have provoked the current worldwide trend of(More)
