Philips HeartStart OnSite Replacement Pads

The HeartStart OnSite uses snap-in SMART Pads cartridges that contain the electrode pads and cable in one replaceable unit.

Adult SMART Pads Cartridge - M5071A

The Philips Adult SMART Pads Cartridge is designed for adult patients and patients weighing at least 55 lb (25 kg). The disposable cartridge installs directly into the HeartStart OnSite AED and should be replaced after use or when it reaches its expiration date.

Infant/Child SMART Pads Cartridge - M5072A

The Infant/Child SMART Pads Cartridge is intended for children under 8 years old or weighing less than 55 lb (25 kg). When this cartridge is installed, the OnSite automatically adjusts its voice instructions and reduces its defibrillation energy for the pediatric patient.

The HeartStart OnSite does not use the Philips Infant/Child Key. That accessory is used with the HeartStart FRx.

Philips HeartStart OnSite Battery

The HeartStart OnSite uses the Philips M5070A long-life lithium manganese dioxide battery. Philips specifies a minimum five-year shelf life before installation and approximately four years of typical standby life after installation when stored and maintained according to the manufacturer's instructions.

The same Philips battery is also used with the HeartStart FRx, so listings may refer to it as an OnSite/FRx battery.

HeartStart OnSite Carrying Cases

Philips offers both standard and slim carrying-case options for the OnSite. The appropriate case depends on how much storage space you need for the AED and additional response supplies.

• Standard Carry Case - M5075A: Provides additional storage space for supplies such as spare pads or a battery.
• Slim Carry Case - M5076A: Provides a more compact option for storing and transporting the AED.

CPR Savers also offers additional protective carrying options, including water-resistant or waterproof-style cases for applicable storage needs.

AED Cabinets, Wall Mounts & Signs

Wall cabinets, mounting brackets and AED signage can help keep the HeartStart OnSite visible and accessible in workplaces, schools and other public-access locations.

Available storage options include surface-mount and semi-recessed cabinets, wall mounts and compact AED storage systems. Select a cabinet or mounting solution appropriate for the environment where the AED will be installed.

Philips Fast Response & Responder Kits

Response kits contain additional supplies that may be useful during an AED emergency. Philips' Fast Response Kit includes items such as protective gloves, a pocket mask, paramedic scissors, a chest-hair razor and an absorbent towel.

CPR Savers also carries responder kits and related emergency accessories that can be stored with the AED.

Choosing a HeartStart OnSite Configuration

CPR Savers carries several HeartStart OnSite configurations, including models with a slim carrying case, standard carrying case and additional protective-case options. The AED itself remains the HeartStart OnSite platform; the primary difference between these listings is the included carrying and storage configuration.

If you already own an OnSite AED, you generally only need to replace consumable items such as pads and batteries as they are used or reach their replacement date.
