Official Description

CRA Chrono is an application for doctors and nurses to rhythm Cardio-Pulmonary Resuscitation (CPR). Two different sound signals triggered every 2 to 4 minutes help to identify the temporal analysis of heart rate and adrenaline injection times. This medical timer automatically counts the number of cycles of CPR, the total adrenaline rush and the total duration of resuscitation. In addition, a metronome can be activated to facilitate chest compressions with a rate of 100/min.
