HeartSine has taken an innovative approach to maintenance items by incorporating the AED batteries and electrodes into one single-use cartridge called the Pad-Pak. The advantage to the Pad-Pak is that there is only one date to monitor and only one item to replace on expiration or after use.
Each Pad-Pak has a 4-year life, and provides 60 shocks or 6 hours of continuous monitoring. When battery power is down to 10 shocks or less, the HeartSine Samaritan AED emits an audible prompt.
The Adult Pad-Pak is gray in color and is for patients from 8 years old to adults and weighing >25 kg/55 lbs.
