Abstract:
This paper describes some issues on the development of a real-time remote monitoring system for patients. This system aims at improving and facilitating the accessibility of medical care professionals to the vital signals of hospitalized patients, or patients that need to be closely monitored while in their own homes. By resorting to remote monitoring systems, the need for medical staff to physically move next to each patient to supervise their clinical condition is supplanted through the remote monitoring of parameters required for evaluation of their physical condition.
To make the use of the system for the medical care professionals easier, intuitive interfaces were developed using Web technologies, where an Internet browser is the only tool required to access the system.
The focus of this paper are on the difficulties and challenges in the design and implementation of a distributed remote patient monitoring system through Internet, and on the technologies that are the most adequate for that purpose.
With this study was concluded that the data updating based on database pooling system (periodic searches) might not be the best solution, because the system is not scalable. It was also found that monitoring several patients simultaneously (in the same browser) is a high-demand processing at the client machine, because the draw graphics (especially in the case of ECG).
