Stop the drop – perioperative patient warming

Effective, continuous patient warming helps managing the risk of hypothermia. It reduces the number of surgical site infections and other complications, reduces patient anxiety and improves recovery times. This means higher throughput of patients and saved resources. 

BARRIER® EasyWarm® active self-warming blanket provides a patient-warming solution that is both easy-to-use and designed for the whole perioperative environment. Once opened and unfolded, the blanket reaches operational temperature within 30 minutes and maintains an average temperature of 44C for up to 10 hours1.

BARRIER EasyWarm active self-warming blanket benefits

Dr. Mark Kyker, Cardio Thoracic Anesthesiologist


Where does the heat in the blanket come from?

  • The heat of the active self-warming BARRIER EasyWarm blanket is produced via an exothermic chemical reaction initiated by exposure to air, resulting from the oxidation of iron.
  • The contents of the warmers are all-natural: activated carbon, iron, water, salt, clay and the chemicals are securely contained in 12 separate pockets.
  • The pockets are designed and positioned to provide the maximum heat transfer in the most efficient manner. Average temperature of 44ºC is reached within 30 minutes.
