Life Corp.'s Life StartSystem AED and emergency oxygen unit weighs only 8 pounds and is smaller than a briefcase at 12x12x3 inches. Durable and water resistant, it comes complete with Life O2 6&12 liters per minute (LPM) "Norm and High" emergency oxygen in a disposable/replaceable or refillable 15-minute-supply aluminum cylinder and a Life CPR Mask that universally fits adults and children. The system can be used for first-aid emergency oxygen administration and if needed before fibrillation or after successful defibrillation (purchase Philips' "OnSite" AED separately).
