A microcontroller-based portable electrocardiograph system
2004
The ambulatory acquisition and monitorization of electrocardiograms (ECG) under not controlled conditions, is a practice of paramount importance in cardiology diagnosis nowadays. The ECGs are acquired while patients develop their normal life, using a portable device. The storage capacity of such devices usually ranges from 24 to 48 hours. ne systems used to perform this task are the so-called Holter systems. In this paper we describe a low cost single channel Holter system, based on a microcontroller, to register the ECG signal continuously during up to 48 hours. This microcontroller system runs off batteries, and includes many peripherals such as a display, keyboard, serial interface, soli…
A Novel Expert System for Non-Invasive Liver Iron Overload Estimation in Thalassemic Patients
2014
Expert Systems can integrate logic based often on computational intelligence methods and they are used in complex problem solving. In this work an Expert System for classifying liver iron concentration in thalassemic patients is presented. In this work, an ANN is used to validate the output of the L.I.O.MO.T (Liver Iron Overload Monitoring in Thalassemia) method against the output of the state-of-the-art method based on MRI T2 assessment for liver iron concentration. The model has been validated with a dataset of 200 samples. The experimental Mean Squared Error results and Correlation show interesting performances. The proposed algorithm has been developed as a plug in for OsiriX Dicom View…
Sepsis in head and neck cancer patients treated with chemotherapy and radiation: literature review and consensus
2015
Abstract: The reporting of infection/sepsis in chemo/radiation-treated head and neck cancer patients is sparse and the problem is underestimated. A multidisciplinary group of head and neck cancer specialists from Italy met with the aim of reaching a consensus on a clinical definition and management of infections and sepsis. The Delphi appropriateness method was used for this consensus. External expert reviewers then evaluated the conclusions carefully according to their area of expertise. The paper contains seven clusters of statements about the clinical definition and management of infections and sepsis in head and neck cancer patients, which had a consensus. Furthermore, it offers a revie…
MEDiSN
2008
Staff shortages and an increasingly aging population are straining the ability of emergency departments to provide high-quality care. Moreover, there is a growing concern about the ability of hospitals to provide effective care during disaster events. Tools that automate patient monitoring would greatly improve efficiency, quality of care, and the volume of patients treated. Towards this goal, we have developed MEDiSN, a wireless sensor network for monitoring patients' vital signs in hospitals and disaster events. MEDiSN consists of Patient Monitors which are custom-built, patient-worn motes that sample, compress and secure medical data, and Relay Points that form a static multi-hop wireles…
Flat panel displays for medical monitoring systems
2005
Flat panel displays are ideal for demanding hospital and clinic applications like vital sign monitoring and bedside administration. They take up much less space than conventional monitors (CRT based) and can be wall-mounted, cart-mounted or used on a desk stand. User friendly interface demands easy to use input device, rotary position encoders and touch screen panels offers simplicity replacing bulky keyboards. This article will present an overview about today's medical monitoring systems tendencies, describing as an example, a custom medical monitoring module developed to be integrated in an assisted ventilation system.
The EU project "United4Health": Results and experiences from automatic health status assessment in a Norwegian telemedicine trial system.
2017
Introduction Patients with chronic obstructive pulmonary disease require help in daily life situations to increase their individual perception of security, especially under worsened medical conditions. Unnecessary hospital (re-)admissions and home visits by doctors or nurses shall be avoided. This study evaluates the results from a two-year telemedicine field trial for automatic health status assessment based on remote monitoring and analysis of a long time series of vital signs data from patients at home over periods of weeks or months. Methods After discharge from hospital treatment for acute exacerbations, 94 patients were recruited for follow-up by the trial system. The system supported…
Recommendations for clinical monitoring of patients with acid sphingomyelinase deficiency (ASMD)
2018
Abstract Background Acid sphingomyelinase deficiency (ASMD), a rare lysosomal storage disease, results from mutations in SMPD1, the gene encoding acid sphingomyelinase (ASM). As a result, sphingomyelin accumulates in multiple organs including spleen, liver, lung, bone marrow, lymph nodes, and in the most severe form, in the CNS and peripheral nerves. Clinical manifestations range from rapidly progressive and fatal infantile neurovisceral disease, to less rapidly progressing chronic neurovisceral and visceral forms that are associated with significant morbidity and shorter life span due to respiratory or liver disease. Objectives To provide a contemporary guide of clinical assessments for di…
Photoplethysmography system for blood pulsation detection in unloaded artery conditions
2012
Photoplethysmography (PPG) is an optical method of blood pulsation recording and has been extensively studied for decades. Recently PPG is widely used in the medical equipment for patient monitoring and in laboratories for research and physiological studies. In spite of the technological progress in the field of medical equipment, there are no generally accepted standards for clinical PPG measurements up to date. One of the most important factors affecting PPG waveform is the contact pressure between tissue and PPG probe. The aim of the current study was to develop and evaluate a system for software-assisted PPG signal acquisition from the unloaded artery. Novel PPG waveform derived Optimal…
Towards Improved Healthcare Performance: Examining Technological Possibilities and Patient Satisfaction with Wireless Body Area Networks
2009
Published version of an article from the journal: Journal of Medical Systems. he original publication is available at Springerlink. http://dx.doi.org/10.1007/s10916-009-9291-8 This paper investigates the benefits of using less intrusive wireless technologies for heart monitoring. By replacing well established heart monitoring devices (i.e. Holter) with wireless ECG based Body Area Networks (BAN), improved healthcare performance can be achieved, reflected in (1) high quality ECG recordings during physical activities and (2) increased patient satisfaction. A small scale clinical trial was conducted to compare both technologies and the results illustrate that the wireless ECG monitor was able …
Analysis of the written handover process during shift changes within the hospital
2008
This study assesses the ergonomic quality of a new writing format used for the written transmission of activity during a nurse’s handover in a hospital. This format called “targeted or focussed transmission” comes from a new prescription of hospital management designed to improve the written handover process. Our research focused on the information filtering process for each patient concerned by a shift handover. A three step methodology was designed, with the participation of 9 nurses in charge of 70 patients : (1) nursing work analysis before the handover, (2) oral handover analysis, (3) written handover analysis. Results show that the new writing format does not match the nurses’ needs t…
