PRODUCT INFORMATION

Defibtech · Automated Chest Compression

Lifeline ARM XR Automatic Chest Compression Device

A 16.4 lb mechanical CPR device (model RMU-2000) that delivers 100-110 compressions per minute at a depth the device sets itself from the patient's anterior-posterior chest diameter. A suction-cup piston provides active recoil; one 18 V lithium-ion battery runs it for an hour. It packs into a 21 x 19 x 11 in. Backpack case for ambulance, ED and rotary-wing use.

Manual compression quality falls off inside two minutes and nobody notices from the inside. A machine does not get tired during a forty-minute extrication.

Figures above are Defibtech's device specifications. The chest width and height figures are the device's mechanical fitting limits, not a clinical patient-selection rule. Whether to place a mechanical CPR device on a given patient, and how it fits into your resuscitation algorithm, is governed by your protocol, your medical direction and Defibtech's instructions for use.

▾Who Carries It

EMS agencies running cardiac arrests through extended extrication, stair evacuation and long ground transport, where manual compression quality is the limiting factor · Emergency departments and resuscitation teams holding compression quality steady through procedures and staff changeover · HEMS and critical-care transport where in-flight manual CPR is impractical · Industrial and remote medical programs with long definitive-care intervals.

Scope of practice and training. This is a clinician-operated resuscitation device. Placement, mode selection, interruption management and integration with defibrillation and airway management require device-specific training and operation under your protocol and medical direction. Follow Defibtech's instructions for use.

FREQUENTLY ASKED QUESTIONS

How does the Lifeline ARM XR automatically adjust compression depth?

The ARM XR measures the patient's anterior-posterior (AP) chest diameter from the piston position when first applied. It then targets a compression depth of 1.8 to 2.2 inches — the AHA/ERC recommended range — within its available depth range of 1.5 to 2.4 inches. This automatic calibration ensures appropriate compression depth for both smaller and larger adult patients without manual operator adjustment. The device is not restricted by patient weight, only by chest dimensions (width max 17.5 in; height 7.4–12.7 in).

What is active chest recoil and why does it matter in the ARM XR?

Active chest recoil refers to the device physically lifting the chest wall between compressions using suction from the cup-shaped piston design, generating up to 0.6 inches (1.5 cm) of upward displacement. Complete chest recoil between compressions allows the thoracic cavity to re-expand, which generates negative intrathoracic pressure that draws venous blood back into the heart — a critical determinant of cardiac filling and coronary perfusion pressure during CPR. Manual CPR often achieves incomplete recoil due to rescuer fatigue and body weight; the ARM XR delivers consistent active recoil throughout the resuscitation.

How long does the ARM XR battery last and how quickly does it recharge?

The 18V, 5600 mAh lithium-ion battery provides approximately 1 hour of continuous operation on a nominal patient at 25°C. The battery recharges in less than 3 hours in the device, or less than 2 hours when charged externally using the optional charging dock. Battery life is approximately 3 years with normal charge/discharge cycling. Replacement battery packs are available. For extended operations, carrying a second charged battery is recommended.

What are the two compression modes on the ARM XR and when is each used?

Continuous mode delivers uninterrupted compressions suitable for use with asynchronous mechanical ventilation (advanced airways where ventilations and compressions are not coordinated). Protocol mode (30:2) delivers 30 compressions followed by a 3-second pause with audio indication for 2 rescue breaths, suitable for basic airway management or two-rescuer CPR protocols following standard AHA/ERC guidelines. The mode should match the team's airway management approach and institutional CPR protocol.

Is the Defibtech Lifeline ARM XR comparable to the LUCAS device?

The ARM XR is a direct competitor to the LUCAS mechanical CPR device at a lower price point. Both deliver AHA/ERC-compliant compressions; key differences include the ARM XR's active recoil suction cup design vs. LUCAS's active decompression piston, and weight of 16.4 lb vs. approximately 14 lb for LUCAS 3. The ARM XR's backpack carry case design offers practical transport advantages in EMS and HEMS environments. For institutions evaluating mechanical CPR solutions, the ARM XR provides comparable clinical performance at a more accessible cost.
