The examination of reliability of data using a waterproofing case for a small medical measuring apparatus during scuba diving

Sampling clinical data during scuba diving is technically challenging, since equipment for measuring the data can not be used in the water. In a previous study, a waterproof case, with which clinical data (e.g., SPO2 and hart rates) can be measured in the water, was developed. The aim of the present study was to examine the validity of data that is collected by using the waterproof case. The following conclusions were obtained from the results of this study. 1) SPO2 and hart rates collected by attaching the waterproof case to participants' hands were compared with the one that was collected without the case. The results revealed no significant difference in those measures, indicating accurate measurements can be obtained by using the case. 2) Previous studies have reported that sampling clinical data during scuba diving should be included in medical checks for divers. The present study showed that the sampling method using the waterproof case makes such a medical check possible. An index of diving safely can be obtained with the method.
