title: [A Quantitative Verification for Operability of Three PCA Devices Attached to the Disposable Infusion Pumps].
abstract: BACKGROUND
  In this study using 3 different PCA devices (Baxter infuser LVBB +PCM 2 ml: Pump B, Coopdech Balloonjector +PCA 3 ml: Pump C, Rakuraku fuser +PCA 3 ml: Pump S), we investigated how easily PCA devices could be handled.
  
  
  METHODS
  In this study with 42 volunteers (14 elders and 28 nurses), we compared 3 PCA ejection volume and ejection rate among three PCA devices. PCA ejection rate was defined as the ratio of actual ejection volume to the maximum ejection volume (MEV) of each PCA device.
  
  
  RESULTS
  Although not only elders but also nurses failed to produce accurate PCA ejection volume in the Pump B, Pump S could provide the MEV even by elders. In the Pump C, approximately 80% of MEV could be achieved by nurses, but 60% of MEV by elders (P < 0.05).
  
  
  CONCLUSIONS
  Our data suggested that accuracy of PCA ejection volume might be dependent on PCA device.
