The management of applied research projects requires an organized and efficient methodology to manage economic resources, establish clear and achievable objectives and balance the competitive demands of different stakeholders. In Colombia there are programs that support social investment projects, which have very demanding requirements and controls, being a challenge for higher education institutions...
In this work we propose a methodology to analyze the elastic energy interaction at the atomic level between Si self-interstitials and extended defects in crystalline Si. The representation of this energy in maps in 2D planes shows the anisotropic nature of the elastic interaction. This elastic energy maps can be used to understand diffusion trajectories of Si self-interstitials around extended defects...
This paper shows the design of a wearable device for measuring vital signs, oriented to monitoring applications and home health care. In order to improve the living conditions of the patient, device allows that the patient can perform their daily activities while their health is monitored. The designed device allows measuring electrocardiogram, blood oxygen saturation, non-invasive blood pressure...
The assessment of biomedical technology framed in the Ministry of Social Protection Decree # 4725 of 2005 performed as part of the acquisition processes is of great importance for health care institutions in Colombia.. Medical technology, being costly and complex, requires detailed processes with rigorous methodologies that guarantee an accurate assessment and transparent acquisition process. The...
The metrological confirmation is one of the most widely used methodologies for guaranteeing the correct performance of biomedical equipment. This methodology consists of calibration, maintenance, and set-up with recalibration. Also, the correct selection of the equipment to be calibrated, maintenance frequencies, maximum allowed error and actions to be taken, makes crucial to have accurate methodologies...
There is a death risk that increases with the required time to transport a critical patient to a hospital by ambulance. Effectiveness of medical attention and therefore patient’s safety will strongly depend on the quickness to determine appropriate actions to be performed when patient arrives to the hospital. It is evident the need of establishing a communication link between monitoring equipment...
Mechanical ventilation (MV) is a clinical therapy that becomes necessary when the ventilatory capacity of patients is depressed by pathophysiological reasons or post-surgery conditions like cardiac surgery. 22.7% of patients undergoing cardiac surgery require mechanical ventilation over 24 to 48 hours. [1]. In these patients, the mortality rate may exceed 40%. It is known that the main cause of failure...
This article is the first intent to solve the problems of saturation and low efficiency in the emergency department of a high complexity level hospital, using the technological surveillance as a tool that finds options who solve the problem. The presented approach seeks to obtain clear, impressive, reliable and timely technological information for the Hospital, and from this make decisions that respond...
This paper presents an electronically enabled system that uses piezoresistive sensor arrays to acquire information from plantar pressure distribution. The system has been designed as a low-cost alternative to diagnostic equipment for orthotic insoles, biomechanical studies, and sports medicine. The system allows autonomous biomechanical analyses that include dynamic and static tests, with similar...
This paper presents a systemic approach to technology assessment in acquisition processes, describing four stages that are executed sequentially and generates as output quantitative indicators that facilitate the choice of either technology. We present an application to the case of the acquisition of 164 units for clinical dental training at the School of Dentistry at Universidad de Antioquia demonstrating...
This paper shows the results of the analysis, characterization and modeling of basal ganglia intracerebral signals recorded during surgical intervention of patients with Parkinson's disease (PD). Statistical tests are used, both graphical and numerical analysis of normality and stationarity of signals sampled at varying time windows (0.5 s, 1 s, 2 s, 3 s, 4 s and 5 s). Subsequently characterization...
This paper presents a novel approach to simulate neurosurgical interventions, which can be used for training in schools of medicine. It is based on the implementation of a benchtop model as an alternative to reported virtual reality-based approaches. The system includes a surgery planning software, 3D models of skull, an electromagnetic fields navigation system and compatible instrumentation. To our...
The mechanical ventilator settings in patients with respiratory diseases like chronic obstructive pulmonary disease (COPD) during episodes of acute respiratory failure (ARF) is not a simple task that in most cases is successful based on the experience of physicians. This paper describes an interactive tool based in mathematical models, developed to make easier the study of the interaction between...
In development countries the vital signs data measurement normally is performed at hospitals or laboratories where patients remain under observation with many electrodes attached on the body. The integration of biomedical data acquisition systems and information technologies (IT) enables continuous real time monitoring of physiological data in daily life, which improves patient's medical care and...
