Cardiovascular Diseases (CVDs) are a major concern. They are responsible for 35% of deaths and for costs of billions of dollars worldwide. Prevention of CVDs has become a global priority. Comprehensive use of wearable devices operating in the context of Internet-of-Things (IoT) paradigm is the key to monitor, diagnose and treat CVDs. Most of the previous approaches propose wearables only for non-invasive...
Blood pressure (BP) is one of the vital signs for assessing the cardiovascular health condition of a person. In recent years, the continuous non-invasive monitoring of BP is of great interest in routine and critical bedside monitoring. Previous studies have shown that pulse transit time (PTT), time taken by the pressure wave to travel between two arterial locations can be a potential indicator of...
Blood Pressure (BP) is one of the vital signs in the clinical assessment of patients in both acute and chronic care settings. However, existing BP measurement devices are less portable or invasive and do not allow continuous ambulatory monitoring. In this study, we propose a non-invasive BP-monitoring system using an efficient mathematical model and algorithm to measure the BP by relating Pulse Wave...
This paper focuses about the implementation of a secure authentication model for the wireless body area network using the features of biological signals and the process of shared key establishment during the time of configuration. There is a need for a secure online health monitoring system for Wireless body area network, but currently all the system engineered are working with complex key exchange...
According to WHO(World Health Organization), estimated about 17 million people die around the world due to cardio vascular diseases, particularly heart attack, in them most of the deaths are due to untimely intervention. If proper medical care can be given to the patients at the right time their lives can be saved, for that all we need is a system that continuously monitors ones ECG signal, so we...
Blood potassium concentration [K+] has a strong influence on ECG and particularly on T-wave morphology. We previously developed a method to quantify [K+] from ECG analysis. The aims of the study were i) to test this method quantifying [K+] on a larger group of hemodialysis (HD) patients ii) to give a mechanical interpretation of the link between [K+] and ECG by testing the estimator on congenital...
Non-contact, non-invasive monitoring of hemodynamic parameters would be ideal for medical monitoring in a variety of environments. Radio Frequency Impedance Interrogation (RFII) measures hemodynamic function via resonance frequency coupling to a hydrophilic protein molecule. While the application of this technology to hemodynamic monitoring has demonstrated initial success, this preliminary study...
Non-contact, non-invasive monitoring of hemodynamic parameters has long been deemed to be important to medical monitoring in a variety of environments. Radio Frequency Impedance Interrogation (RFII) measures hemodynamic function via resonance frequency coupling to a hydrophilic protein molecule. We examined the use of RFII for hemodynamic monitoring of human subjects during Lower Body Negative Pressure...
Nowadays, the rate of people incoming to the emergency room pointing a health problem is steadily increased. This paper introduces a new telemedicine framework that addresses this problem. It allows medical experts to estimate the real health condition of conditional (c-) patients, and then consult them to visit a hospital or not. This framework combines elements such as an expanded electronic medical...
Monitoring cardiac output (CO) is important for the management of patient circulation in an operation room (OR) or intensive care unit (ICU). We assumed that the change in pulse wave transit time (PWTT) obtained from an electrocardiogram (ECG) and a pulse oximeter wave is correlated with the change in stroke volume (SV), from which CO is derived. The present study reports the verification of this...
To make street orienteering sports attractive and interesting to global online viewers it is important to build a system that is capable of tracking mobile competitor positions in real-time using global positioning systems (GPS) and wireless networking to collect information at a central server to be displayed to the viewers. Another important aspect of such a real-time system is the ability to monitor...
This paper introduces an implementation of portable multi-parameter tele-monitor terminal(PMTT). This terminal is reliable, portable, real-time and high cost-effective, which can tele-monitor many kinds of vital bio-signals and GPS signal through GPRS, such as electrocardiogram(ECG), blood pressure, oxygen saturation, blood glucose, body temperature, respiration and so on. The Samsung's S3C2410a is...
We developed and tested the Berkeley Tricorder, a health monitoring device capable of measuring a subject's ECG, EMG, Blood Oxygenation, Respiration (via Bioimpedance), and motion--almost equivalent to the feature set of a hospital bedside patient monitor. Our focus has been a highly integrated design incorporating the radio and all associated circuitry on a single PCB. The device stores data locally...
In monitoring a patient's real-time vital signs through Body Area Networks (BAN), rich data sources are communicated to medical practitioners. The benefit of BANs may be negated if medical practitioners are overloaded with streams of BAN data. It is essential that data is delivered in a timely context aware manner. In this paper a BAN designed for falls assessment among elder patients (65+ years)...
Patients admitted to the Intensive Cardiac Care Unit are closely monitored by different devices that generate alarms when an abnormality is detected. However, most alarms do not signify a life-threatening event. During a four month period 34,827 alarms were collected electronically. The most frequent alarm categories were related to mechanical ventilation (42.2%), blood pressure (32.3%), electrocardiogram...
This paper describes a robust healthcare monitoring system which possess multiple physiological signals measurements on real time that applicable to various environments which integrates wireless sensor network (WSN) technology and code division multiple assess (CDMA) with extended feature of locally standalone diagnosis algorithms that implemented in cell phone. A simple database is created inside...
Nocturnal hypoglycaemia has been implicated in the sudden deaths of young people with diabetes. Experimental hypoglycaemia has been found to prolong the ventricular repolarisation and to affect the T wave morphology. It is postulated that abnormally low blood glucose could in certain circumstances, be responsible for the development of a fatal cardiac arrhythmia. We have designed a monitoring and...
