Philips M5071A AED Pads (Adult): The Fast Buyer’s Guide to Choosing, Checking Expiry, and Installing Correctly

Summary:
The Philips M5071A pads are the official adult SMART Pads for the Philips HeartStart OnSite (HS1) and Home AEDs. These are the pads that deliver life-saving shocks and communicate with the AED to guide the rescue. You should always keep a spare set on hand and replace them before the expiration date.


What Are Philips M5071A Pads and Which AEDs They Fit

  • Official Name: Philips M5071A Adult SMART Pads Cartridge

  • For Use On: Adults or children weighing 55 pounds or more (usually age 8 and up)

  • Compatible With: Philips HeartStart OnSite (HS1) and HeartStart Home AEDs

  • Not For: Philips FRx AED (that model uses SMART Pads II)

  • Single Use: Replace after each rescue or when expired

  • Sealed Cartridge: Keeps the adhesive and gel ready for quick use


How To Pick the Right Pads

  1. Check Your AED Model
    If your AED says HeartStart OnSite or Home on the front, the M5071A pads are correct. If it says FRx, you need SMART Pads II.

  2. Adult vs Pediatric

    • Adult pads: M5071A (for age 8 and up)

    • Pediatric pads: M5072A (for under 8 years or under 55 lb)

  3. Check Expiration Date
    Pads expire after about two years. Always keep one set installed and one sealed spare.


Why You Should Always Keep a Spare Set

  • Readiness: Once you use a set, your AED can’t be used again until new pads are installed.

  • Avoid Backorders: Sometimes suppliers run low, so it’s smart to keep extras.

  • Compliance: Many organizations must keep AEDs ready at all times.


How To Replace M5071A Pads

  1. Open the AED lid or power it off.

  2. Release and remove the old cartridge.

  3. Insert the new M5071A cartridge until it clicks.

  4. Close the lid or cover.

  5. Confirm the AED’s status indicator shows “ready.”

Tip: Check your AED monthly to make sure the ready light is on and the pads are still sealed and in date.
