Defibtech Lifeline ARM Compression Device

CPR has a measurable statistic called CCF which means “chest compression fraction.” It is the percentage of time in which chest compressions are done by rescuers during a cardiac arrest.  CCF drops if there are interruptions or pauses in CPR, which may be due to other rescue related activities, even if they last only 2-3 seconds. Greater CCF can impact survival.

CPR efficacy is attainable with Defibtech’s latest technical innovation, the Lifeline ARM, an automated solution for providing mechanical CPR when effective manual CPR is not possible. Time is of the essence in a rescue. The superior design of the Lifeline ARM results in easier assembly, fewer steps to beginning compressions, minimized interruptions, and robustness during operation. With state of the art features, functions, and ease of use, the Lifeline ARM is an unsurpassed solution for automated CPR.  Designed for the ruggedness and durability demands of the professional first responder, the Lifeline ARM delivers portability, quick deployment, and ensures high quality CPR. The result is a truly useful product to help save lives.

Simple to Use

The Lifeline ARM has an extremely simplified Control Panel where just two steps are needed to initiate mechanical CPR: (1) Adjust the Compression Piston height relative to the patient’s chest for beginning compressions by using the Up / Down softkey buttons located on the Control Panel of the Compression Module, and (2) depending on the protocol that is in line with your designated emergency response procedures, choose between “Run Continuous,” which performs chest compressions only (no breathing) for continuous chest compressions, or “Run with Breaths,” which follows the compressions with breaths protocol by using programmed pauses for rescue breaths. Toggling between the two protocols during the rescue is allowed, to accommodate your local resuscitation protocol. And, at any time, the Pause button may be used to stop compressions when running, or resume compressions if stopped.

Be it on the ground, in an ambulance cot, or at the hospital, the Lifeline ARM automated CPR device is your solution for uninterrupted CPR. To see a video of the Lifeline ARM’s unique design showcasing its modularized compression piston.

Long Life Rechargeable Battery

Advanced battery technology, with flexible power options, means the Lifeline ARM automated CPR device will always be ready for rescue. The rechargeable battery pack provides unmatched operational times and long service life across a wide temperature range. By design, fast battery pack swapping, as well as external AC power adapter operation, is possible.

• Long runtime battery pack life (requires less power to accomplish compressions)
• Fast battery pack recharge time
• Long useful life battery pack (3 years or about 300 charge/discharge cycles)
• Battery pack inserts in either orientation (with the contacts toward the unit)
• Fast battery pack swapping because of battery pack eject release latches
• External AC power adapter also recharges the battery pack, even during use
• An optional charging station can charge up to two battery packs simultaneously and independently: recharge one depleted battery pack in 2 hours, or two depleted battery packs in 3 hours

Designed for the Real World

Any lifesaving technique requires a high level of excellence in its delivery during an emergency intervention. Such is the case with CPR, where the quality and speed of each and every compression is critical to a successful clinical outcome. According to AHA/ERC guidelines, CPR requires maintaining 2 inches/5cm depth compressions at a rate of 100 per minute.The quality of CPR is hard to maintain when fatigue can occur in as little as 1-2 minutes impacting efficacy.The Lifeline ARM helps ensure the high quality and continuous CPR associated with better survival for cardiac arrest patients when effective manual CPR cannot be performed. The Lifeline ARM automated CPR device has many applications and benefits for patients and the professionals from many disciplines called to rescue them. When CPR is needed for long durations, while in a moving vehicle, during intra-hospital transport, or when rescue teams are shorthanded, the Lifeline ARM automated CPR device ensures the high-quality and continuous CPR associated with better survival for victims of sudden cardiac arrest (SCA).

Lightweight Rigid Frame

Nicely balanced and lightweight, the Frame’s single piece design provides increased structural integrity during compressions by facilitating operation of the Compression Piston without undue deflection or distortion that could compromise consistent compression depth, an important element for effective CPR. Providing enhanced usability during deployment and repacking, the Frame effortlessly snaps into the Backboard, and releases just as easily.

Highly Visible & Portable

The pace is fast and furious during a rescue. The Lifeline ARM automated CPR device comes packed in a red canvas carrying case designed for backpack portability. The structured bag contains a custom solid foam insert for holding the Lifeline ARM components and spare items, all of which make the device portable, easy to deploy and use, and pack up again quickly.

Ergonomic Design

The innovative and elegant design of the Lifeline ARM device affords portability, speedy deployment, and smooth, consistent operation. The Frame’s single piece design enhances its usability and provides an incredibly strong platform for performing mechanical CPR. The Compression Module contains the Control Panel, a removable and rechargeable battery pack, and the piston drive used to generate the chest compressions.  Modularization of the Compression Piston has benefits in all phases of use, particularly during deployment and repacking. It allows the Frame and Backboard to be attached to the patient and aligned before the addition of the Compression Module. Periodic servicing will be so much easier too.

The Frame’s design makes it easy to line it up and connect with the self-locking and self-centering latches of the Backboard, speeding deployment and reducing pinch points. The Compression Piston is supported by the Frame in a drop-in module that self-aligns when inserted into the Frame and swiftly locks into place with a simple twist. The single use Patient Interface Pad is a cushioned snap clip design that connects to the Compression Piston and remains firmly in place. The interior space of the arched Frame was designed to accommodate a very broad range of adult patient sizes.

Easy to operate Backboard release levers, located on each side of the Frame, are used to release the Frame from the Backboard. For increased accessibility, there are two sets of Backboard release levers within the Frame sides offering multiple options for releasing the Frame from the Backboard. The latches may be released together or one at a time.

Automated Chest Compression

The Lifeline ARM automated CPR device is comprised of a state-of-the-art Compression Module paired with a specially designed Frame. Smooth operation results from an innovative custom Piston and brushless DC motor design housed within the Compression Module. During operation, a smart, software driven, motor control algorithm ensures compression depth and rate consistency by compensating for variability in chest resistance ensuring CPR efficacy.

Real-Time Protocol Selection

The Lifeline ARM automated CPR device is designed to accommodate local resuscitation protocols. In accordance with your emergency response procedure during a rescue, you may choose the corresponding softkey button to select between chest compressions only (no breathing) or chest compressions with rescue breaths, for performance according to the compressions-with-breaths protocol. When using the compressions-with-breaths protocol, a reminder chirp and flashing LED are used as notifications during the three compressions prior to the device pausing for the operator to give rescue breaths. If needed, the user may toggle between the two protocols during the rescue.

Ruggedness & Durability

The structural design and choice of materials of the Frame and Backboard result in an extremely durable and impact resistant device, making it one tough unit. Built to exacting standards, the Lifeline ARM automated CPR device is manufactured to withstand small particulates and water spray, and meets military standards for shock and vibration testing.
