In the measurement of sleep apnea the attachment of monitors to the patient's body can impose a burden. Thus, only visual observation of the respiration pattern has been reported and in the present study, we evaluated an image analysis system that did not require the attachment of any monitors, or invasive procedures, to measure respiration. This system was initially reported by Takasaki et al. in 1998. In the present study, we observed sleep apnea in 12 patients using the image analysis system and also a Microsleep simple monitor. The findings in both methods showed a regular respiratory pattern resembling Cheyne-Stokes respiration. A comparison of the respiration patterns resembling Cheyne-Stokes respiration in a 1-hour period (CSI), the apnea index (AI), and the decrease in blood oxygen saturation index (ODI4), showed a correlation between CSI and AT and ODI4. Thus, our results showed that the image analysis system was effective for studies of sleep apnea syndrome.
