Chest compression (CC) quality is decisive for survival and good neurologic outcome of patients in sudden cardiac arrest [1,2] . Both the 2015 European Resuscitation Council and American Heart Association guidelines advise the CC should be performed at recommended depth and rate [1,3] . According to Kurowski et al chest compressions are often too shallow, and hands-of time is to long [4] . This issue becomes even more complicated by the need of the rescuer to wear chemical, biological, radiations, nuclear, personal protective equipment (CBRN-PPE) which adversely affects fine motor skills [5] .
