- Primary Outcome Measures
Name Time Method Differentiating pulse (as a surrogate parameter of cardiac output activity) from its absence can help medical staff make decisions regarding the care of patients with cardiac arrest, PEA or asystole. Especially in the case of pseudo-PEA, pulse control can be significantly more difficult in the presence of a weak pulse pressure wave. In addition, in ROSC - under resuscitation - perfusion of the cerebral vessels is of great importance.<br>There is a descriptive research question. What percentage of the ultrasound loops shown are correctly named by the students. Pulsation of the common carotid artery present? Yes, or No. Using B-, M-mode or the colour Doppler. <br>
- Secondary Outcome Measures
Name Time Method Are the sequences demonstrated later assessed better or is there a kind of learning effect for the students in the course of the test? Is the decision made faster and / or more correctly with increasing test duration?<br>Do the test results differ depending on the level of education or which semester the students belong to?<br>Are there differences in the correct recognition of a pulselessness or an existing pulse depending on whether the sequences are displayed in B-, M-mode or via colour Doppler?
