Abstract

The aim of the bachelor’s thesis was to create a cardiopulmonary resuscitation simulator for laymen. The simulator was implemented for the purpose of practicing chest compressions combined with artificial ventilation. The chest compressions were performed by measuring acceleration using an accelerometer placed on the commercial device CPR Simulator EVE-B (Hivista), which also served as a benchmark for comparing compressions and the measured data. Artificial ventilation was constructed using a 281637 Flow Sensor (Hamilton Medical) supplemented with an MPXV7002DP differential pressure sensor (NXP Semiconductors) that feeds into a Labquest 2 imaging unit (Vernier). The entire system of the designed and commercial comparative solution is built into a sub-realistic model of a teddy bear with a height of approximately 120 cm. Measurements and calibrations were performed on the partial parts of the cardiopulmonary simulator, as well as on the overall assembled bear-type simulator. Accelerometer and volumetric flow sensor results are more accurate than the commercial simulator benchmark. Overall, the simulator model is mounted in a bearoid phantom and fully functional with CPR training quality displays on both the mobile phone and the Labquest 2.
