title: [Message measurement and feedback cardiopulmonary resuscitation board: a monitor for standard cardiopulmonary resuscitation].
abstract: OBJECTIVE
  To invest a message measurement and feedback cardiopulmonary resuscitation (CPR) board which could guide the first aid to perform standard CPR.
  
  
  METHODS
  The multifunctional and intelligent CPR board which could not only support but also provide standard parameters and frequency of compression for first aid was placed underneath the patient's back, with his head in the concave headrest at the top of the board. The operator exerted chest compression with his hands according to the 2005 American heart association (AHA) guidelines for CPR, and adjusted the pressure and rate according to that showed on the board to achieve the force and frequency of chest compression according to the standard.
  
  
  RESULTS
  The operation of the chest compression which was carried out on the message measurement and feedback CPR board was significantly better than that carried out on the ordinary board because that the former could show the pressure and rate of chest compression, so it could guide the first aid to attain an optimal CPR according to the standard. Furthermore, as the force of chest compression exerted was optimized, adverse effects of forcible chest compression such as fracture of sternum or ribs could be avoided.
  
  
  CONCLUSIONS
  The message measurement and feedback CPR board is able to feed back the pressure and rate of the process of chest compression in CPR. Therefore, it can help monitor the CPR manipulation, thus improves its quality and also avoids unfavorable side effects.
