The exposure to air pollution from both sources natural or anthropogenic is one of the main risk factors that affect progressively the health. Given this problem, this paper presents an emulator mechatronic system of an average adult respiratory tract. This instrument can continuously measure temperature, relative humidity and inhalable particles entering to the respiratory tract. With the integration...
In Mexico, INEGI in 2012 published that the 14,756 deaths occurred in the country, 19% had a cardiovascular origin. The largest number occurred in male. On the other hand, at 2011 in Baja California, and it was reported as the main cause of death in the reproductive-age population. The Framingham Heart Study represents a rapid application in the prognosis of occurrence of CVD in at-risk individuals...
The analysis of motor skills and technical gestures in sports guide to the understanding of the biomechanics of the human body. There are many complex interaction mechanisms between body and environment, due to the intrinsic dynamic characteristics that come along with these activities. To understand the above mentioned, we need to have different measurement tools that allow us to know in detail the...
In this paper are proposed three control algorithms, based on the sliding-mode technique, to track a trajectory or regulate the position of four rotational links and a translational link in a 5-DOF Scara robot with an emphasis on medical applications. It is shown that the nonlinear system is globally asymptotically stable and achieves zero steady-state position error. Moreover, the controllers can...
Some factors that have increased cardiovascular incidents are sedentary lifestyle, poor eating habits, smoking, stress; hence the importance of continuously monitor cardiac activity in people. This research proposes the implementation of a wireless system to monitor the heart allowing visualization of the electrocardiogram (ECG) on a mobile device via Bluetooth (BT) technology and Arduino UNO board...
The incidence of cardiovascular diseases is rising, so more people are requiring cardiac services. The private service is very expensive; hence the public health sector is exceeded by their capacity to accomplish this demand. The proposal to solve this problem is the implementation of a wireless network based on Bluetooth (BT) for recording, monitoring and analysis of electrocardiographic signals...
Some cardiac signal components are fragmented, attenuated and delayed when an infarct occurs in the ventricles. These micropotentials are called ventricular late potentials (VLPs) and normally appear in the end of the QRS complex and/or at the beginning of ST segment. VLPs have been used to detect sudden cardiac death risk in postinfarcted patients. Due to their very low amplitudes, late potentials...
This document presents a method for coupling and recording of signals from an electrocardiogram (ECG) and three electronic stethoscopes, as well as for the synchronized graphic display of the ECG and phonocardiogram (PCG) signals. This tool presents a visualization interface that assists teaching of the cardiac cycle and can be of support in non-invasive diagnosis of the heart. Low cost ECG and EE...
