4. Thoraxkompression ohne Beatmung bei der Laienreanimation?

Author

Kreimeier, U., Dirks, B., Arntz, R., Bahr, J., Goldschmidt, P., Roessler, M., Sasse, M., and Toursarkissian, M.

Abstract

Zusammenfassung: Die lebensrettenden Basismaßnahmen (Basic Life Support, BLS) umfassen die Aufrechterhaltung freier Atemwege sowie die Unterstützung von Atmung und Kreislauf ohne Hilfsmittel, abgesehen von Infektionsschutzmaßnahmen. Die neueste Handlungsempfehlung der American Heart Association (AHA) vom 31.03.2008 beinhaltet die Forderung, dass Notfallzeugen eines außerklinischen Herzstillstands vermutlich kardialer Genese bei Erwachsenen, die nicht oder nicht mehr ausreichend in der kardiopulmonalen Reanimation (CPR) geübt sind, ausschließlich eine Herzdruckmassage ohne Beatmung durchführen sollen („compression-only CPR“). Notfallzeugen, die mit der CPR vertraut sind, wird nunmehr die Wahl zwischen konventioneller CPR (Herzdruckmassage mit Beatmung im Verhältnis 30:2) oder alleiniger Herzdruckmassage überlassen. Auf der Grundlage evidenzbasierter Medizin und unter Hinzuziehen auch neuester wissenschaftlicher Erkenntnisse ist es derzeit nicht vorgesehen, die aktuellen Reanimationsleitlinien des European Resuscitation Council (ERC) für „Lebensrettende Basismaßnahmen für Erwachsene“ zu ändern oder zu ergänzen. Sowohl der German Resuscitation Council (GRC) wie auch der ERC sehen keinerlei Änderungs- oder Ergänzungsbedarf für Europa und bleiben dabei, dass allein Laienhelfer, die nicht gewillt oder unfähig sind, eine Mund-zu-Mund-Beatmung durchzuführen, die CPR ausschließlich mittels Thoraxkompressionen durchführen sollten. Es wird betont, dass die Ausbildung von jugendlichen Laienhelfern und die Etablierung von Schulungsprogrammen durch Hilfsorganisationen und in Schulen stärker gefördert werden müssen.

41. Homogenous concept for the coupling of active and passive single-mode devices by utilizing planar gradient-index lenses and silicon-V grooves

Abstract

A new concept for a common interface between passive and active single-mode devices is proposed. The submicrometer alignment accuracy necessary for efficient coupling of single-mode devices is extended to the range of some 10 [[micro]meter] by beam expansion with planar gradient-index microlenses; the increased angular sensitivity is satisfied by the use of planar surfaces. The imaging system is used off axis, resulting in a suppression of backreflections in the range >60 dB. Of many possible variations of components (fibers, waveguides, optoelectronic integrated circuits, edge-emitting lasers, vertical-cavity surface-emitting lasers, photodiodes), the coupling of fibers and waveguides is examined in detail. Expected coupling efficiency and sensitivity to lateral misalignment are calculated by use of a modified beam-propagation method. In this way, the overall performance of the connector can be compared with existing connector concepts, and the feasibility of the concept is proven. Experimental results for the fiber-fiber connector are given.

42. Index-distributed planar microlenses for three-dimensional micro-optics fabricated by silver-sodium ion exchange in BGG35 substrates

Abstract

Fabrication of planar microlens arrays by silver-sodium ion exchange is possible by using a new glass type, optimized for this technology. Because of its nonlinear diffusion response it is well suited to the fabrication of microlens arrays. We show that the diffusion coefficient can be described theoretically by an exponential concentration dependence. The parameters of the planar microlenses are measured interferometrically and by imaging experiments. Because of the specific index distribution, new evaluation techniques for the determination of lens parameters from interferometric measurements have been applied. We also present a simple model that relates the achievable lens parameters to the diffusion conditions. Key words: Ion exchange, planar microlenses, gradient index.

Abstract

One of three science instruments onboard Mars Odyssey is the Mars Radiation Environment Experiment (MARIE), which is described here. MARIE is an energetic particle spectrometer which will characterize the space radiation environment of Mars and determine its risk to human exploration. Additional information is contained in the original extended abstract.
