The LIFE LINE emergency oxygen resuscitation kit is designed not just for use by medical professionals such as doctors and dentists but also by appropriately trained first aid personnel in the work place and community. LIFE LINE from BOC allows first-aiders to administer oxygen during CPR while waiting for an ambulance to arrive. It is also designed to provide initial treatment for conscious patients during medical emergencies. Please note medical oxygen is NOT included in this kit and must be purchased separately.
