start of 1:1-Block public summary

Brief Summary in Lay Language

The analysis of videomicroscopic recordings of the microcirculation (e.g., the blood circulation under the tongue = sublingual microcirculation) is time-consuming and requires an experienced observer in order to obtain reproducible results. Aim of the study is to evaluate the success of a standardized, inter-active training of novice users of the method. We will recruit medical students and residents, provide the standardized, inter-active tutorial and ask them to analyze a standard video recording of the sublingual microcirculation. The result of their analysis will be compared with the results of experts. Our hypothesis is that novice observers trained by our standard, inter-active tutorial are able to generate reproducible results.
