Low-G Mattress Overlay Installed on a Hospital Bed

CMD Innovations, LLC is proud to offer new patented technology in skin pressure protection with our Low-G® Skin Pressure Protection System. The Low-G mattress overlay is our flagship product and was developed to protect skin tissue from conditions that lead to the formation of pressure ulcers. Pressure ulcers, also known as bedsores or decubitus ulcers, are open wounds that are caused by constant pressure restricting the normal flow of blood in tissue. Pressure, friction, and physical well being contribute to the problem. Pressure ulcers are most common in individuals with limited mobility. See Figure A for intrinsic and extrinsic factors that can lead to pressure ulcers.

Low-G technology evolved through years of research and development in the aerospace industry. Since 2010, the Low-G has undergone thousands of hours of clinical trials in hospitals, long term care facilities, and by home care providers. Feedback has been positive and the Low-G has been met with enthusiasm by medical patients, staff, and administrators. During initial trials, we worked with Olympic Medical Center, in Port Angeles Washington. After more than 13,000 equivalent days of patient use, only a single pressure ulcer occurrence was reported. Evaluators praised the Low-G, not only as a prevention tool, but also for its ease of deployment, and comfort. Unlike alternating overlays, the Low-G is stationary, silent, requires no external power, is not prone to patient falls, and is easily sanitized with bleach.

Intrinsic/Extrinsic Factors

The Low-G mattress overlay was designed to be used on top of a standard hospital bed and covered by a standard bed sheet. Durable, light-weight overlay has a visco-elastic foam core and a skin-like outer membrane that keeps moisture out. Edge vents allow the overlay to breathe and not trap body heat. The Low-G works by maintaining skin pressure below the threshold that prevents proper blood flow in the areas in contact with the overlay's surface. The standard Low-G can support patients weighing up to 350lbs. For heavier patients, two overlays may be stacked. Because the Low-G can be sanitized and reused for multiple patients, storage issues may be eliminated by leaving the overlay deployed. In addition, the non-slippery surface of the Low-G has shown to be effective at preventing transfer-related patient falls.

Low-G Cost Savings Analysis


"Our staff and patients were so thrilled with the product that we have now deployed 40 Low-G® surfaces to cover all the beds in our units. This overlay is an amazing tool that we can use to help us prevent pressure ulcers during hospitalization." — Lorraine Wall RN, MSN, Assistant Administrator/CNO Olympic Medical Center

"The Low-G® Overlay has proven to be a wonderful tool in terms of fall reduction. It is much easier for the patients to position themselves using this product without the same fear of falling to the floor which some tend to experience when using an airbed. Turning of patients on a airbed requires a two-person assist, but with the Low-G Overlay, a single person can easily manage the task, saving time for our employees so that they can use that time to focus on other patient care." — Sarah Moore, R.N., Director of Nursing, Crestwood Convalescent Center
