Abstract
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 inci-dences. IDH may lead to nausea, vomiting, or anxiety. In some severe cases, there will be accident like shock and death. Moreover, patients’ physical monitoring is easily interrupted, and medical quality is often compromised, as nurses in a hemodialysis center joggle many tasks at the time. Therefore, the purpose of this paper is to integrate the technologies of wireless sensor networks (WSN) technologies, global systems for mobile communications (GSMs), and a MySQL database to construct an automatic monitoring system to collect physical data during hemodialysis. And an alert can be immediately sent to family members and nurses if IDH occurs. We then apply this wireless monitoring technology to the patients with IDH. This system is applied to an indoor space. The system framework includes two parts: the wireless networks and the controlling platform. During hemodialysis simulations, the average success ratio of physical data transmitting is 94.84%, the average reliability of systolic pressure is 1, of diastolic pressure is 0.89, and of pulse is 0.94, 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.
