This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performances of algorithms to detect deteriorations from the resulting wearable sensor data were similar to those used with routinely collected intermittent data, suggesting that it is feasible to use wearable sensors to continuously assess the likelihood of deterioration. However, the false alert rate increased when using wearable sensor data due to the continuous, rather than intermittent, monitoring. Therefore, further work is required to improve algorithms to detect deteriorations from wearable sensor data to provide clinically useful alerts.

Available in PDF, EPUB and Kindle. Book excerpt: This book trains the next generation of scientists representing different disciplines to leverage the data generated during routine patient care. It formulates a more complete lexicon of evidence-based recommendations and support shared, ethical decision making by doctors with their patients. Diagnostic and therapeutic technologies continue to evolve rapidly, and both individual practitioners and clinical teams face increasingly complex ethical decisions. Unfortunately, the current state of medical knowledge does not provide the guidance to make the majority of clinical decisions on the basis of evidence. The present research infrastructure is inefficient and frequently produces unreliable results that cannot be replicated. Even randomized controlled trials (RCTs), the traditional gold standards of the research reliability hierarchy, are not without limitations. They can be costly, labor intensive, and slow, and can return results that are seldom generalizable to every patient population. Furthermore, many pertinent but unresolved clinical and medical systems issues do not seem to have attracted the interest of the research enterprise, which has come to focus instead on cellular and molecular investigations and single-agent (e.g., a drug or device) effects. For clinicians, the end result is a bit of a “data desert” when it comes to making decisions. The new research infrastructure proposed in this book will help the medical profession to make ethically sound and well informed decisions for their patients.
Download or read book Early Detection of Inpatient Deterioration Using Wearable Monitors written by Timothy Bonnici and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Therefore, we undertook an systematic evaluation of algorithms to estimate respiratory rate from the ECG and PPG in order to identify algorithms which might be clinically useful. We identified 4 algorithms which were more accurate than electrical impedance pneumography when operating in ideal circumstances. Further work is required to determine whether performance will be maintained in a real-world context. Finally, we examined whether continuous monitoring offered any advantage over intermittent observations according standard ward practice. We concluded that although individual patients might have benefitted from continuous monitoring, at the population level the benefit was minimal and outweighed the cost of the false alerts. The principle reason for lack of benefit was the low prevalence of abnormal vital signs. Future work should continue to address the technical and practical issues surrounding the design and implementation of wearable monitoring systems. In parallel research needs to be undertaken to gain a better understanding of which care processes are failing, what should be monitored and how the data can be used to improve the reliability of existing care.
Download or read book Towards Continuous Mobile Sensing for Remote COPD Monitoring written by Daniyal Liaqat and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chronic Obstructive Pulmonary Disease (COPD) is a debilitating and life-threatening disease. In 2016 there were an estimated 251 million cases of COPD globally and the World Health Organization predicts that by 2030 COPD will be the third leading cause of death worldwide. Technologies that help people with COPD manage their condition could have significant impact on their lives. The work presented in this thesis outlines a system that uses wearable and mobile devices to passively sense and monitor patients with COPD. Mobile and wearable devices contain a myriad of sensors and have been used in applications ranging from earthquake detection to flight control for drones. To make these devices relevant for COPD monitoring, this thesis focuses on two signals that can be extracted from wearable sensors, respiratory rate and coughing. To detect respiratory rate, we propose WearBreathing -- our system for respiratory rate detection using the accelerometer and gyroscope sensors found in smartwatches. While respiratory rate from a smartwatch has been done in previous works, existing methods are only accurate in in-lab settings and while participants are stationary, making them unsuitable for remote monitoring. Therefore, WearBreathing is designed specifically to operate in the wild and we show that it is indeed more accurate in the wild than existing methods. Similar to respiratory rate, we found that existing cough detection solutions do not perform well in the wild. Using an in-the-wild dataset that we collect from COPD patients, we first characterize the sounds captured by a smartwatch microphone in a wild setting. Using our dataset, we build a state of the art cough detector, which we call CoughWatch that works on in-the-wild data and is more accurate than existing cough detectors. Finally, because mobile devices are resource constrained devices designed for intermittent use, battery life becomes a significant concern when attempting to continuously monitor sensor data. End users, such as patients with COPD, are unlikely to use a device that provides only a few hours of battery life per charge. Therefore, we propose Sidewinder, a developer friendly hardware architecture for energy efficient continuous sensing on mobile devices.

Download or read book Breathing Monitoring and Pattern Recognition with Wearable Sensors written by Percy Nohama and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter introduces the anatomy and physiology of the respiratory system, and the reasons for measuring breathing events, particularly, using wearable sensors. Respiratory monitoring is vital including detection of sleep apnea and measurement of respiratory rate. The automatic detection of breathing patterns is equally important in other respiratory rehabilitation therapies, for example, magnetic resonance exams for respiratory triggered imaging, and synchronized functional electrical stimulation. In this context, the goal of many research groups is to create wearable devices able to monitor breathing activity continuously, under natural physiological conditions in different environments. Therefore, wearable sensors that have been used recently as well as the main signal processing methods for breathing analysis are discussed. The following sensor technologies are presented: acoustic, resistive, inductive, humidity, acceleration, pressure, electromyography, impedance, and infrared. New technologies open the door to future methods of noninvasive breathing analysis using wearable sensors associated with machine learning techniques for pattern detection.

Download or read book Ambient Sensor Based Respiratory Rate Sensing System written by and published by . This book was released on 2019 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ambient Sensor based respiratory rate monitoring has been one of the emerging and most attractive field of research in of healthcare advancements. Market study shows that there is multidisciplinary need for continuous monitoring of vital signs. A set of ambient vital sign monitoring sensors are studied in thesis. Pyroelectric infrared (PIR) sensor is used for non-contact based resting respiration rate estimation. This infrared system monitors and records the chest motion of a subject using the analog output signal of the PIR sensor. The analog output signal is a composite motion of the inhale-exhale process and the vibrations of heartbeat. This system proposes a low cost and an effective way to estimate the respiratory rate, which is an important biological marker. Respiration rate is estimated based on the inhale and exhale breathing chest motion detected by the pyroelectric infrared sensors. This thesis aims to review the literature on contact and non-contact methods of respiratory monitoring and to propose a non-contact system for respiratory rate monitoring and estimation

Download or read book Contactless Vital Signs Monitoring written by Wenjin Wang and published by Academic Press. This book was released on 2021-09-20 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vital signs, such as heart rate and respiration rate, are useful to health monitoring because they can provide important physiological insights for medical diagnosis and well-being management. Most traditional methods for measuring vital signs require a person to wear biomedical devices, such as a capnometer, a pulse oximeter, or an electrocardiogram sensor. These contact-based technologies are inconvenient, cumbersome, and uncomfortable to use. There is a compelling need for technologies that enable contact-free, easily deployable, and long-term monitoring of vital signs for healthcare. Contactless Vital Signs Monitoring presents a systematic and in-depth review on the principles, methodologies, and opportunities of using different wavelengths of an electromagnetic spectrum to measure vital signs from the human face and body contactlessly.
