Amidst all the talk about the risk of an influenza pandemic, little has been said about the difficult decisions that would have to be made in an overwhelming health care crisis. An article in the February issue of Academic Emergency Medicine, the Official Journal of the Society for Academic Emergency Medicine, outlines a sample set of guidelines for prioritizing the use of a piece of equipment likely to be in short supply in a pandemic: mechanical ventilators.
Drs. John L. Hick and Daniel T. OLaughlin of University of Minnesota propose a concept of operations and a set of suggested guidelines for triage of mechanical ventilators in a pandemic or bioterrorist attack. "When a large-scale pandemic does occur, were simply going to run out of resources," comments Dr. Hick. "We need to be talking now about how we are going to allocate scarce resources to the patients most likely to benefit from them."
Drs. Hick and OLaughlin developed their proposal after a recent drill showing that an epidemic affecting ten percent of the Minneapolis area would lead to a "rapid and critical shortfall" in the supply of mechanical ventilators. "Despite a surge capacity of between 2,500 and 3,500 beds in the area, there were 16 ventilators available in our regional system," says Dr. Hick.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
