Air-free HotDog Patient Warming uses Waffle-Grip safety technology to defeat high rates of hypothermia in procedures with unique positioning challenges including robotics, GYN, urology and colorectal. Hypothermia is common during Trendelenburg positioning due to the minimal surface area available to warm. This innovative HotDog solution allows complete underbody warming with the safest and best underbody warming system available. Unique waffle pattern evenly disperses grip on the patient using mechanical hold and friction (following AORN recommendations), which reduces localized shearing forces and eliminates risk of brachial plexus injury. HotDog Waffle Grip is less expensive than most Trendelenburg positioners, easy to use and safer than cutting and taping egg crate foam.
