The R15 can be safely stored in public, accessible areas and work places, ready for any cardiac or airway emergency. It is easily activated using three simple steps: remove tape, turn lever to activate the R15 and attach mask to mouth/nose. It can be carried anywhere, especially to remote areas for easy access until the EMS can arrive. The R15’s 15 minutes of emergency 100% oxygen can be used on a person struggling to breath while you can perform uninterrupted chest compressions until the EMS arrive. Effective CPR provided by a bystander in the first few minutes of cardiac arrest can increase survival 2 or 3 times. Every second without oxygen can negatively affect survival: improve your emergency preparedness program by adding emergency oxygen with the R15.
