Abstract
Technological innovations in the field of disease prevention and maintenance of patient health have enabled the evolution of fields such as monitoring systems. One of the main advances is the development of real-time monitors that use intelligent and wireless communication technology. In this paper, a system is presented for the remote monitoring of the body temperature and heart rate of a patient by means of a wireless sensor network (WSN) and mobile augmented reality (MAR). The combination of a WSN and MAR provides a novel alternative to remotely measure body temperature and heart rate in real time during patient care. The system is composed of (1) hardware such as Arduino microcontrollers (in the patient nodes), personal computers (for the nurse server), smartphones (for the mobile nurse monitor and the virtual patient file) and sensors (to measure body temperature and heart rate), (2) a network layer using WiFly technology, and (3) software such as LabView, Android SDK, and DroidAR. The results obtained from tests show that the system can perform effectively within a range of 20 m and requires ten minutes to stabilize the temperature sensor to detect hyperthermia, hypothermia or normal body temperature conditions. Additionally, the heart rate sensor can detect conditions of tachycardia and bradycardia.
Highlights
Because of changes in technology, a continuous evolution is occurring in industries such as medical services, industrial manufacturing, and comfort services
We found that the smart multi-level tool for remote patient monitoring (SMTRPM) needs at least ten minutes to acquire an accurate value for the body temperature (BT)
The results show that the SMTRPM could be used to measure the heart rate (HR) variability parameters to alert heart attacks or other HR disorders
Summary
Because of changes in technology, a continuous evolution is occurring in industries such as medical services, industrial manufacturing, and comfort services In these industries, technological advances must be monitored to support decisions or actions that could benefit the processes supporting the industry. A smart monitoring system could measure the patients’ progress in real time, providing continuous feedback on the improvement in the health of patients who have undergone treatment. Integrating intelligent monitoring systems could improve care by providing the nurses with efficient documentation and timely access to information [2]. A real-time smart multi-level tool for remote patient monitoring (SMTRPM) is proposed that integrates two cutting-edge technologies, WSN and MAR, to support nurses and physicians in PHIs. The SMTRPM uses WiFi technology to transmit data, reports, and alarms to a nurse server or mobile device in wireless mode.
