A flexible firmware architecture for different kinds of data acquisition systems, ranging from high-precision bench instruments to low-cost wireless transducers networks, is presented. The key component is a multi-behaviors finite state machine, easily configurable to both low- and high-performance requirements, to diverse operating systems, as well as to on-line and batch measurement algorithms. The proposed solution was validated experimentally on three case studies with data acquisition architectures: (i) concentrated, in a high-precision instrument for magnetic measurements at CERN, (ii) decentralized, for telemedicine remote monitoring of patients at home, and (iii) distributed, for remote monitoring of building's energy loss...

BACKGROUND: Timely monitoring of obstructive sleep apnea (OSA) therapy can be a challenge amid conflicting pressures of rising patient volume and shortage of sleep medicine providers. Positive airway pressure (PAP) devices with wireless modem technology have the potential to improve patient access to care and streamline work load, yet little is known about patient attitudes toward telehealth integration among veterans with sleep apnea. As part of a larger quality improvement initiative at the Veterans Affairs (VA) Puget Sound Health Care System, we elicited veterans' preferences toward modem versus traditional PAP data download, including patient attitudes and factors affecting those preferences...

Despite having the basic tools necessary to appropriately identify and manage individuals with hypertension for over half a century it remains the single greatest contributing risk factor to morbidity and mortality worldwide today. Since diagnosis and effective treatment availability are not issues, this major failing in care can be attributed to inadequate systems of care: systems that have led to only <20% of hypertensive individuals globally having their blood pressure adequately controlled. Even in the US, where it is one of the most common reasons for a primary care visit, and with over $42...

Exercise periodic breathing (EPB) is associated with exercise intolerance and poor prognosis in patients with heart failure (HF). However, EPB detection during cardiopulmonary exercise test (CPET) is difficult. The present study investigated the use of a wireless monitoring device to record the EPB during CPET and proposed quantization parameter estimates for the EPB. A total of 445 patients with HF were enrolled and underwent exercise tests. The ventilation data from the wearable device were compared with the data obtained during the CPET and were analyzed based on professional opinion and on 2 automated programs (decision tree [DT] and oscillatory pattern methods)...

OBJECTIVE: To assess the long-term efficacy of antireflux surgery on Barrett's esophagus (BE) using BRAVO wireless pH monitoring. BACKGROUND: BE is associated with chronic gastroesophageal reflux and esophageal cancer. Till date, studies have failed to demonstrate that preventing gastroesophageal reflux with antireflux surgery halts the progression of BE, often because of difficulties in objectively proving an effective antireflux barrier. METHODS: Since 1991, all patients undergoing antireflux surgery across 2 hospital sites have been followed in a prospective database...

Continuous patient monitoring systems acquire enormous amounts of data that is either manually analysed by doctors or automatically processed using intelligent algorithms. Sections of data acquired over long period of time can be corrupted with artefacts due to patient movement, sensor placement and interference from other sources. Owing to the large volume of data these artefacts need to be automatically identified so that the analysis systems and doctors are aware of them while making medical diagnosis. Three important factors are explored that must be considered and quantified for the design and evaluation of automatic artefact identification algorithms: signal quality, interpretation quality and computational complexity...

Wireless sensor networks (WSNs) are being used in a wide range of applications for healthcare monitoring, like heart rate monitors and blood pressure monitors, which can minimize the need for healthcare professionals. In medical system, sensors on or in patients produce medical data which can be easily compromised by a vast of attacks. Although signature schemes can protect data authenticity and data integrity, when the number of users involved in the medical system becomes huge, the bandwidth and storage cost will rise sharply so that existing signature schemes are inapplicability for WSNs...

BACKGROUND: The brain, made up of billions of neurons and synapses, is the marvelous core of human thought, action and memory. However, if neuronal activity manifests into abnormal electrical activity across the brain, neural behavior may exhibit synchronous neural firings known as seizures. If unprovoked seizures occur repeatedly, a patient may be diagnosed with epilepsy. PURPOSE: The scope of this project is to develop an ambulatory seizure monitoring system that can be used away from a hospital, making it possible for the user to stay at home, and primary care personnel to monitor a patient's seizure activity in order to provide deeper analysis of the patient's condition and apply personalized intervention techniques...
