The emergency health service is for all interventions that are made up of people who have received special education in their field, who work together in order to provide the best emergency response to the sick and injured in the shortest time possible in line with the possibilities available. In this context, although the emergency health service provided during the pandemic process requires the implementation of special procedures for healthcare professionals, it is important in the validation of the biomedical devices used during the provision of this service. Especially the fact that this process was a disaster that took place in an unexpected time period caused everyone to be caught unprepared and this situation caused the current workload of healthcare workers to increase even more. In this study, we conducted a literature search to shed light on the problems experienced by 112 emergency healthcare professionals during the pandemic period and how the validation of the biomedical devices used by these personnel in the ambulance should be. The type of research is descriptive research. The Covid-19 pandemic was accepted as a case and the literature was reviewed, with this case being the focus. During the literature search, up-to-date keywords such as "emergency health service, Covid-19, disaster preparedness, emergency aid unit employees, biomedical device technologies", which are also mentioned in the keywords, were scanned. Care was taken to ensure that the studies included in the review section were up to date and in accordance with the academic guide. In addition, due to the limitation of resources in the validation section of the research, assistance was received from the relevant legislation and expert medical company engineers and from the active staff in the field of healthcare professionals' problems. As a result of this research, we have reached the conclusion that legal regulations should be made regarding the problems experienced by healthcare professionals due to the pandemic and that existing standards related to device validation should be updated after the pandemic.
