The basics, a LUCAS and an SGA: A simulation study of the deployment of the Lund University cardiopulmonary assist system D Daly, A Ormazabal National Ambulance Service College, Dublin, Ireland Objective: The purpose of the research reported in this paper was to investigate, using data gathered from simulated Out of Hospital Cardiac Arrest (OHCA) exercises, the impact on the quality of chest compressions when introducing a King Laryngeal-Tube (KLT) airway and then employing the LUCAS mechanical CPR device or employing the LUCAS and then securing the KLT airway. These findings may also provide EMS practitioners with evidence-based guidance on how to better employ the LUCAS in an OHCA. Methods: Student paramedic 2-person crews were assigned a simulated call for a “58 y/o patient, not conscious, not-breathing”. On entering the scene, the crew finds an adult manikin supine, on the floor. The crew managed the initial stages of a simulated adult OHCA VF simulation using a simple, well-practiced BLS drill, a LUCAS, and a Supra-Glottic-Airway (SGA) while minimising interruptions to chest compressions. Results: The primary outcome measure was the length of time that no chest compressions were taking place in each simulated scenario. A significant statistical difference was found between the LUCAS-first condition, with a mean time off the chest of 4.63 s and the Airway-first condition, which had 5.25 s, z (−8.509) with critical value 1.96. Conclusion: The data showed the difference between a two-stage deployment of the LUCAS before and after the KLT airway was statistically significant in favour of the LUCAS first group, however, it was considered not clinically significant as the difference in the time off the chest was less than 10 s between the two conditions.


MULTIDISCIPLINARY RESEARCH/APPLICATIONS
In the field of nanotechnologies and surfaces, Andromede responds to the great need of very high resolution surface analysis tools both in mass spectrometry and in ion imaging. Access to the chemical characterization of a nanometric volume is envisaged.

APPLICATIONS BIOLOGIE, HEALTH, IONIC IMAGING
The use of nanoparticle beam (Nanoparticle Probe in Biology (NPB)) as a probe in biology is the results of research on particle-matter-secondary emission interaction conducted at IPNO in the last few decades. The offer of analysis was then opened to bioorganic surfaces with the emergence of metallic cluster beam and molecular beams.

ASTRO-CHEMISTRY, COSMO-MATERIALS, ION IMAGING
The availability of cluster beams and high energy nanoparticles make it possible to simultaneously determine the elemental and molecular composition of a complex surface such as meteorites. These analyses of cosmo-materials by mass spectrometry and ion imaging can be supplemented by simulation to obtain analogs in the laboratory.

APPLICATIONS IMPLANTATION IN MATERIALS
Andromede provides the scientific community molecular beams of methane, fullerenes and metal clusters for studying the behavior of materials under irradiation. The scientific fields studied are the modification of materials under irradiation or implantation, the aging of materials, study of solid physics, microelectronics, cosmo-materials and earth sciences.

R&D SOURCES D'IONS
The Andromeda platform has two sets of ion source development. a filtered NAPIS ionic column dedicated to R & D around LMIS, LICIS and vacuum electro-spray type sources for the production of cluster beams or molecular beams with great brightness. TANCREDE beam line for ion beam developments with ECR type sources. These two systems are available for all new developments with our support and the contribution of our expertise on these kinds of source.

Characteristics of the Secondary Ion Emission
Andromede is crucial for achieving a major objective, nanoscale co-localization of tagged proteins in cell membranes. Is it possible ?
Comparison with other techniques: keV Bismuth clusters IONTOF V Pegase 500 keV Nanoparticles beams Andromede set-up is unique world-wide, with its capability to perform molecular analysis at the nanoscale with detection limits that are near a single molecule (for MW below 1,500 Da). Yet to be implemented is a molecular imaging capability which promises again to be unequalled.  The fees for scientific expertise (ion beam analyses + analysis report) will be calculated later and will be subject to a quote Note: An inventory of the different calculation and deduction policies on the services of the old laboratories is in progress. Once the rate and the sampling base will be fixed by the management of the IJCLab, the file for the validation of the rates will be sent to the DR4.

// R&D ion sources
In addition to the accelerator platform, ionic columns equipped with the ECR source and the NAPIS source are available to test source developments and to produce new beams. These devices are also available for analysis and material modifications in the low energy range (a few keV)

// Ion beams and characteristics -Source ECR Microgan
The ions produced by this source are selected at the accelerator terminal by a Wien filter.
