A WSN-based wireless monitoring system for intradialytic hypotension of dialysis patients

Intradialytic hypotension (IDH) is a much common complication during a hemodialysis. The prevalence of IDH is about 10-50%. Elderly people, patients with diabetes, and cardiovascular dialysis patients have the highest rate of incidences. IDH may lead to nausea, vomiting, or anxiety. In some severe cases, there will be accident like shock and death. The purpose of this paper is to integrate the technologies of wireless sensor networks (WSN) technologies, global systems for mobile communications (GSMs), and a database to construct an automatic monitoring system to collect physical data during hemodialysis. We then apply this wireless monitoring technology to the patients with IDH. During hemodialysis simulations, the average success ratio of physical data transmitting is 94.841%, where the testing cases are collected from 6 persons, and the time interval is 2 hours. The loss ratio of physical data results from space constraints and data collision.
