A system is disclosed for providing feedback regarding chest compressions in CPR comprising a measuring unit, a processing unit and a display unit, where the measuring unit comprises a depth measuring device, a force measuring device, or both. The processing unit comprises a depth signal device and/or a force signal device and a threshold device. The processing unit is adapted to output a signal depending on the values of depth and/or force signals with respect to the thresholds. The display unit comprises at least one indicator and is adapted to activate the indicators based on the output from the processing device. The system thus measures and processes chest compressions and provides feedback to the user with respect to the characteristics of the compressions.

Display unit for providing feedback in CPR

A device for practicing mask ventilation, comprising a first passage and a second passage. The first passage is designed to provide communication between a source of air and the interior of a patient mask. The patient mask is designed for placement over a person's mouth and/or nose. The second passage is designed to provide communication between the air source and a back pressure means. The back pressure means is adapted to simulate the resistance of a human airway. The device can also comprise a third passage designed to provide communication between a breathing person and the surroundings. The passages may be formed in one integrated adapter to be placed between a patient valve and the mask.
