The Global Safety 5 Pack Foam CPR Floor Mat with Convenient Carry Bag to Reduce Back and Knee Pain, 15.5" x 8" x 0.75" is a great solution for potential pain points in your CPR Training class, or CPR in general. Our 5 Pack Foam CPR Floor Mat with Convenient Carry Bag is built to help you perform more comfortable and ergonomic CPR, reducing lower back and knee pain compared to a hard floor. This helps make CPR Training, or performing actual CPR stress-free so you can focus on the task at hand. The foam in our floor mat is made from nitrile-butadiene rubber, not only providing a comfortable experience, but also minimizing the risk of water absorption from sweat, and the risk of allergic reaction that some might get from a foam mat that includes latex material. This item contains 5 foam CPR floor mats that come neatly packaged within a blue duffel bag, making storage simple and efficient, as well as allowing you to easily carry the mats to wherever you need to go. About 80 percent of all out-of-hospital cardiac arrests occur in private residential settings. Over 1.5 million heart attacks occur each year and approximately 350,000 people die before reaching the hospital. Facts like those are found all over the place due to cardiac arrest being a leading cause of death among people, so being trained to perform CPR can possibly mean the difference between life and death for a loved one.
