Philips HeartStart OnSite Infant/Child Pads Cartridge (M5072A)

Pediatric Cartridge
[IN STOCK]

The Philips M5072A Infant/Child SMART Pads Cartridge is the official OEM pediatric replacement for the Philips HeartStart OnSite (M5066A), Home (M5068A), and HS1 AEDs. Unlike standard adult pads, this specialized cartridge contains a built-in energy attenuator that automatically reduces the defibrillation shock to a safe level (50 Joules) for a child’s smaller heart.

⚠️

Fitment & Patient Verification Rules

Age & Weight Restrictions: This cartridge is explicitly designed for children under 8 years old and weighing under 55 lbs (25 kg).

Hardware Compatibility: Do NOT purchase this for the Philips FRx AED. The FRx model uses a separate, reusable Infant/Child Key (Part # 989803139311) rather than a dedicated pediatric pads cartridge.

🛠️ Master Tech: How to Stop “Chirping” & Install M5072A

Follow this sequence to replace the cartridge and reset your HeartStart AED’s internal computer.

The Clean Reset Sequence

  1. Press the Blue “i” Button: If the AED is chirping, press the flashing blue information button to allow the machine to verbally confirm the error (e.g., “Replace Pads”).
  2. Release Old Cartridge: Locate the latch at the top edge of the AED and slide it to the side to release and eject the expired cartridge.
  3. Disengage Power (If Chirping Persists): Remove the M5070A battery from the back of the unit and wait exactly 30 seconds for the internal memory to clear.
  4. Insert New Pads: Insert the new M5072A cartridge into the well on the front of the unit until it clicks firmly into place. Do not pull the green handle.
  5. Reinstall Battery & Test: Reinsert the battery. The AED will run a self-test and state “Self-Test Passed,” returning the status light to a flashing green.

Status Light Decoder

  • 🟢 Flashing Green (Every 3 Secs): AED is rescue-ready.
  • 🔵 Flashing Blue “i” + Chirp: Maintenance required. Press the button for voice instructions.
  • 🛑 Solid Red / 3 Beeps: Critical System Error. Contact Philips support immediately.

Tech Tip: The most common cause of a chirping AED is actually an expired M5070A primary battery. Always check your battery date when replacing pads.

Frequently Asked Questions

Are the M5072A pediatric pads required for schools and daycares?

Yes. Most state safety regulations require elementary schools, daycares, and pediatric clinics to have the Philips M5072A Infant/Child SMART Pads Cartridge on hand for treating patients under 8 years old or weighing under 55 lbs.

Can I use the Philips M5072A infant pads on an adult?

No. The M5072A cartridge contains a built-in energy attenuator that permanently reduces the defibrillation shock to 50 Joules, which is insufficient to save an adult. Always use the standard M5071A Adult Pads for patients over 8 years old.

Does the M5072A cartridge fit the Philips HeartStart FRx AED?

No. The M5072A pediatric pads are exclusively designed for the Philips HeartStart OnSite, Home, and HS1 models. The Philips FRx model requires a separate, reusable Infant/Child Key (Part # 989803139311) instead of specialized pads.

What is the shelf life of the Philips OnSite pediatric pads?

The Philips M5072A pediatric pad cartridge has a shelf life of approximately 2 years. The exact expiration date is printed clearly on the front of the cartridge housing.
