Introduction. The outbreak of the COVID pandemic was a period of uncer-tainty and tension for healthcare managers, resulting from the lack of knowledge, i.e. about the transmission of the virus, but also from the lack of uniform organisational and treatment procedures. It was the period where the ability to prepare to a crisis situation, to adapt to the existing conditions and to draw conclusion from the situa-tion were critical to keep ICUs operating. The aim of this study was to show the prep-aration of an ICU in Poland to ensure resilience, and also the methods of reacting dur-ing the COVID-19 pandemic on both central and local level. Methods. Based on the EC and WHO guidelines on resilience a matrix of 6 elements and 13 standards as-signed to them was created, with a series of questions from a survey questionnaire. Results. Good management in resilient systems is free access to any resource. A free and transparent flow of information and also well motivated human resources in an appropriate number. Conclusion. Appropriate preparation, adaptation to the existing situation and effective management of crisis situations is an important element of ICU resilience.
