title: Contactless respiratory and heart rate monitoring: validation of an innovative tool.
abstract: OBJECTIVE
  To assess the accuracy of the EverOn™ piezoelectric sensor based contactless heart rate and respiration rate monitoring system.
  
  
  METHODS
  Measurements of the EverOn™ and reference devices were performed in a sleep lab and an intensive care unit (ICU) setting. One minute measurements by both the reference device and the EverOn™ were averaged and compared. Accuracy was defined in accordance with industry criteria.
  
  
  RESULTS
  Respiration rate (RR) accuracy in the 41 children and 16 adults evaluated in the sleep lab was 93.1% and 90.6% respectively, and heart rate (HR) accuracy was 94.4% and 91.5% respectively. For the 42 ICU patients RR accuracy was 82.0% and 75% (versus end-tidal CO(2) and manual respectively), while accuracy of HR was 94.0%. The EverOn™ was found to be superior to the impedance technique in measuring RR.
  
  
  CONCLUSIONS
  The system described was found to be accurate in accordance with regulatory and industry criteria.
