title: [Effects of eye protective device and ear protective device application on sleep disorder with coronary disease patients in CCU].
abstract: OBJECTIVE
  The purpose of this research was to analyze the effects of an eye protective device and ear protective device application on sleep disorder with coronary disease patients in CCU.
  
  
  METHODS
  The research design was set up as a nonequivalent control group non-synchronized design. The subjects were coronary disease patients in the CCU of a tertiary hospital. The subjects were composed of 20 in the group with an eye protective device, 18 in the group with an ear protective device, 17 in the group with an eye protective device and ear protective device and 20 in the control group. The data was analyzed by chi2-test, ANOVA, Repeated measures ANOVA, Sheffe-test, Simple main effect and Time contrast using SPSS Win 12.0.
  
  
  RESULTS
  The hypothesis, 'There are significant differences in sleep quantity among the four groups' was supported (F=1,342.71, p=.000). The hypothesis, 'There are significant differences in the subjective evaluation of the general sleep patterns among the four groups' was supported (F=3,638.73, p=.000). In addition the hypothesis, 'There are significant differences in degree of sleep among the four groups' was supported (F=1,616.61, p=.000).
  
  
  CONCLUSIONS
  It is cost effective and a simple eye protective device and ear protective device should be applied to patients according to their preference and characteristics in the clinical setting.
