CPR (cardiopulmonary resuscitation) press board, also known as cardiopulmonary resuscitation rescue board or cardiopulmonary resuscitation simulator first aid board, is an important auxiliary tool for medical personnel in the process of cardiopulmonary resuscitation rescue. Its main role is to provide better support for patients in some beds when the bed surface is soft, to improve the compression effect and ensure the effectiveness of the CPR process.
