The system developed by the Moscow scientists with the financial assistance of the Russian Foundation for Basic Research and the Foundation for Assistance to Small Innovative Enterprises will instantly allow to detect and measure gas micro-bubbles being formed in blood inside the pump oxygenator. A small device which looks like some kind of a bracelet on the arterial line of the pump oxygenator and is connected to the computer will be recording all bubbles, searching for potentially dangerous ones and will ensure the timely opportunity to get rid of them.
A patient on the operating table is exposed to numerous risks, especially if the operation is so complex, that extracorporeal circulation is required. One of the dangers is a risk of embolism by a gas bubble, which may occur in the process of blood circulation in the pump oxygenator. It is not always clear why the gas bubbles originate, but they do almost in all the cases. The smaller ones, less than 10 microns in diameter are not particularly dangerous, as they quite rapidly dissolve by themselves. As for bigger bubbles, they may plug in a vessel like a cork, thus disrupting normal blood circulation and causing very bad problems for the organism.
In order to avoid such consequences, it is necessary to trace all the bubbles formed in a pump oxygenator, detect the biggest ones as the most dangerous and get rid of them. The matter is that it has only been possible so far to apply a qualitative approach to this problem, but the scientists have not had any clue to solving it at the quantitative level - to detect gas bubbles in blood and to determine their number and size. In other words, the scientists were unable to distribute the bubbles by size.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
