Abstract
Telehealth systems benefit from the rapid growth of mobile communication technology for measuring physiological signals. Development and validation of a tablet PC enabled noninvasive body sensor system for rural telehealth application are discussed in this paper. This system includes real time continuous collection of physiological parameters (blood pressure, pulse rate, and temperature) and fall detection of a patient with the help of a body sensor unit and wireless transmission of the acquired information to a tablet PC handled by the medical staff in a Primary Health Center (PHC). Abnormal conditions are automatically identified and alert messages are given to the medical officer in real time. Clinical validation is performed in a real environment and found to be successful. Bland-Altman analysis is carried out to validate the wrist blood pressure sensor used. The system works well for all measurements.
Highlights
The population of elderly individuals is quickly expanding far and wide
Hypertension is defined as a systolic blood pressure (SBP) equal to or above 140 mm of Hg and/or diastolic blood pressure (DBP) equal to or above 90 mm of Hg
Normal levels of both systolic and diastolic blood pressure are important for the efficient function of vital organs such as the heart, brain, and kidneys [8]
Summary
The population of individuals of more than 65 years of age around the world will achieve 761 million by 2025, more than twofold of the 1990 figures [1]. In India, elderly adult is the fastest growing population, increasing from 6.7% in 1991 to 10% in 2021, who need more health care services [2]. Hypertension and accidental falls are the two emerging public health problems and a barrier to active ageing [7]. Hypertension is directly responsible for 57% of all stroke deaths and 24% of all coronary heart disease deaths in India [9, 10]. The daily blood pressure monitoring leads to better blood pressure control. The daily blood pressure monitoring removes white coat syndrome and leads to better blood pressure control
