Question 5

safety considerations using AED

6 things

Answer 5

• electrical shock to responders
• remove medication patches (can explode)
• avoid use in highly flammable atmosphere
• DON’T place pad over jewellery (it will conduct + burn casualty). But removal is not necessary
• avoid pads over implanted devices (often see or feel under skin, with scar above)
• inappropriate shock (AED can misread need for shock if casualty is fitting, or if vehicle / machinery vibrations are present)
