Extracorporeal life support: moving at the speed of light.

چکیده

Extracorporeal life support (ECLS), or extracorporeal membrane oxygenation (ECMO) as it is also known, has been used to support over 45,000 patients to date. Overall survival is 62%. After many years of no change in equipment and technology, there has been a recent flurry of new pumps, cannulas, and oxygenators available for ECLS use. While the impact of this new technology is not yet completely defined, initial results have found that these systems provide safe support with lower priming volumes and less bleeding complications. New cannulas are also available, some making it easier for venovenous support in patients, from infants through adults. The reported success of ECLS in patients with H1N1 during the 2009-2010 epidemic and the improved survival of patients randomized to the ECMO arm of a recently completed adult study of respiratory failure have also brought ECLS into the spotlight much more than other years. Whether these developments will usher in a new era of ECLS expansion to a wider range of patients will require close consideration and observation. Other areas that need to be further refined include anticoagulation management, treatment of bleeding complications, learning to "nurse" patients in an awake state, such as is done in some European (and a few United States) centers, and neurodevelopmental outcome on a long-term basis.

A Study of the Wear Behavior of a Rail Material

The rail track is one of the most important elements of a railway system. During the passage of trains, the rails are subjected to contact load that comes from the wheels of the train.  The railway track often fails in service due to wear caused by contact fatigue and other wear damage mechanisms that could also limit the life span of the railway infrastructure and railway vehicle. The aim of t...

QED second order corrections on the speed of light at low temperature

We want to study thermal corrections on the speed of light at low temperature considering temperature dependence of photon vacuum polarization tensor at two-loop level in the standard QED‎. It is found that the heat bath behaves as a dispersive medium for the propagation of light and reduces its speed proportional to the second order of temperature‎. ‎Similarities and differences‎, ‎in light ...

Dynamic Analysis of Moving Cables with Variable Tension and Variable Speed

Dynamic Analysis of an axially moving cable with time dependent tension and velocity isstudied in this paper. Tension force and the moving speed are assumed to be harmonic.It is found that there exists a specific value of speed in which natural frequency of the system approacheszero. This specific speed for such a critical condition is called critical speed and it will be proved thatincreasing ...
