Regulatory Classification

Identification

An external cardiac compressor is an externally applied prescription device that is electrically, pneumatically, or manually powered and is used to compress the chest periodically in the region of the heart to provide blood flow during cardiac arrest. External cardiac compressor devices are used as an adjunct to manual cardiopulmonary resuscitation (CPR) when effective manual CPR is not possible (e.g., during patient transport or extended CPR when fatigue may prohibit the delivery of effective/consistent compressions to the victim, or when insufficient EMS personnel are available to provide effective CPR).

Special Controls

*Classification.* Class II (special controls). The special controls for this device are:(1) Nonclinical performance testing under simulated physiological conditions must demonstrate the reliability of the delivery of specific compression depth and rate over the intended duration of use.

#### ● Intended use

The device is an external device that is manually powered and is used to compress the chest periodically in the region of the heart to provide blood flow during cardiac arrest for adult patients.

● Description of the Subject Device

The ENERTRON CPR JACK is a portable cardiopulmonary resuscitation device with a patented feature of consistent and precision compression depth. It includes a frame structure and a compression mechanism. The compression mechanism has a handle connected with a connecting bar to drive a plunger. The compression mechanism keeps the plunging movements in a perpendicular direction. A depth controlling scale is included on the frame structure for presetting the compression depth of the plunger.

Thus, CPR JACK could provide an adjustable preset compression depth. Enertron had conducted two performance tests, one of 4000 strokes and another of 250,000 strokes. These tests demonstrated that consistent compression depth ranging from 1.5" to 2.0" could be consistently maintained. According to a CPR laboratory study of the American Heart Association 1996, it was stated that "Consistence of chest compression or blood flow is desirable to ensure returning of live."

The design of the ENERTRON CPR JACK adopts very few numbers of components. Therefore it is a light weight device and is made easy to carry. In addition, a rescuer can sit on the sitting bars of the frame with the weight of the rescuer offsetting the Therefore, a heavy platform reaction force while performing compression on a patient. is not necessary as it is not necessary to move the patient for more space under the CPR JACK frame structure. This saves rescue time and efforts.

The ENERTRON CPR JACK has an option to add a base board. The base board is for securing the frame structure in a moving environment such as an ambulance or a rescuing boat. Its purpose is to perform the cardiopulmonary resuscitation steadily in a moving environment.

- . Static load and durability tests were performed to ensure the quality of the CPR JACK
- Discussion

The intended uses for the CPR JACK and the two predicate devices are almost the same. The CPR JACK imposes no safety and effectiveness hazards and it serves the intended purposes more effectively.

Two of the predicate devices have knob force indication and the new device (CPR JACK) has a DEPTH indication. According to the AHA recommendation an effective CPR depends mainly on the compression depth, not on compression force. So the new device imposes no safety hazards but effectiveness.

The maximum compression depth for the new device is 2.00 inches and for the Thumper 3.15 inches. The maximum compression for Elcare Grip is 100 lbs. According to the AHA guideline, 2.00 inches should be the maximum compression depth. The CPR JACK has a limiting mechanism for restricting the depth to a maximum of 2.00 inches. Enertron had conducted two performance tests to demonstrate that the consistent compression depth ranging 1.5" to 2.0" could be maintained. These tests were a 4000-stroke test and a 250,000 stroke test. Thus the new device imposes no safety hazards and its effectiveness had been tested.

There is no force indicator for the new device. This is different from its two predicate devices. There is a knob indicator for the Thumper device and a LED force indicator for the Elcare device. It is known that an effective CPR is related to the consistency of compression depth, not to the compression force indicator is not a major contributing factor for a successful CPR. Force indication may be proportional to the actual compression depth but the effectiveness of such correlation may vary from patient to patient. The new device is at least as the predicate devices and is conceivably more effective than its predicates.

Suite 200, 1033 E. Main Street, Alhambra, CA 91801, U.S.A. Fax: [phone] Telephone: [phone]

The compression of the new device and Eleare Grip are performed manually. The Thumper is air powered. These differences are relevant to the compression depth consistence. The new device has depth setting mechanism and passes the depth consistence tests, with an accuracy of 99.99%. Thus the compression depth of 1.5" through 2.0" can be consistently maintained for the new device. A rescuer needs to have strength to compress for a long period of time. Assume the rescuer has enough strength to exccute the CPR manually with the basic requirements for a basic CPR, the three devices are considered to be substantially equivalent.

The stroke count by Thumper is automatically performed. The Grip does that manually with an indicator. The new device does it totally manually. Since the rescuer has to pass the basic CPR training, the stroke control should be a known knowledge to CPR rescuers. Differences in stroke count by the three devices are not important as the rescuers are certified to perform the CPR.

Although the new device and the predicate devices use different constructing materials, they all passed the biological compatibility tests. They all will not cause any contacting biocompatibility hazard to patients. In this regard, they are substantially equivalent.

To restrain a patient, the new device uses the stainless frame and a restraining belt. The Thumper device uses two restraining belts, and the Grip device uses none. During the CPR process using the new device, there is has no moving hazard to the patient since there is a stainless frame and a restraining belt to restrain the patient in position. In this regard, the three devices are substantially equivalent.

Based on the above information and discussion, we certify that the subject device of Class III is to be substantially equivalent to the predicate devices in the US.
