Applications Of Digital Signal Processing

Metric system is used in the healthcare field as well in science field. This is due the fact that the metric system is more precise. It is important to have a standard system in terms of measurement in medical field or else there will be vast amount of error’s.

Health informatics is the subject concerned with the application of information and communications technologies (ICT) to acquire, process, interpret, store, transmit and retrieve health-related and healthcare data, using the derived information and knowledge in healthcare delivery, education, management and research. This paper discusses in detail an overview of health informatics and its applications. It also discusses some advantages and disadvantages of health informatics, identifies some of the recent trends in the health industry as a result of the adoption and implementation of electronic medical records.

The process our prototype package covers is how to assess the state of a patient's essential body functions using vital signs. In order to check a patient's vital signs you must assess their temperature, pulse rate, respiration rate and blood pressure. This process is used by college students who are pursuing a career in the medical field. The part of this process we will be showing is how to properly check someone's pulse and respiration rate.

This technology would help doctors easily monitor their patients at the hospital as well as after they are released. They would be able to not only record a patient’s heart rate but also their body temperature, the patients would also be able to prick their finger with a utensil in the watch. The watch would be able to do a basic analysis of the blood and it would be sent to their doctor so that the patient would not be required to constantly

The profusa biosensor is able to monitor multiple diseases/conditions from tracking chemicals in the body. These include diabetes, Peripheral arterial disease, heart attacks and heart failures. The occurrence of these diseases/conditions, can change the oxygen, glucose levels or blood pressure in the body. The biosensor could potentially result in faster treatment for paramedics when in contact of an unconscious person. The paramedics would be able to look at the patient's’ biomarkers stream and will help them to treat the patient faster, potentially saving their life. In hospitals, it could help aid doctors to better monitor a patient’s health. The profusa biosensor allows the doctor to keep track of the patients’ health even when sent home.

Technology in the health care field is changing each year with new technology improvements. It is also growing dramatically with how fast the population is increasing. Medical technology is responsible for most of the high rates in medical care spending over the past several decades. It plays an important role in patient care, providing data for the diagnosis of diseases, management of patient therapy and health maintenance. Digital innovations have been created for customers to use portable devices that will be easier to gain access to their medical information, monitor their vital signs,

According to the Health Recourses and Services Administration, “Tele health is the use of electronic information and telecommunications technologies to support long distance clinical healthcare, patient and professional health related education, public health, and health administration”(para 1) . Technology is has taken over our every-day lives and has slowly integrated into our health care system. According to Ronda Hughes, “Tele nursing is the use of technology to deliver nursing care and conduct nursing practice” (para 3). The two terms are closely related. Tele nursing cannot be defined without first defining the term of tele health, but what does the tele heath and nursing world look like? What does a tele nurse do and how is it a benefit to the patients and/or the nursing profession?

The technique of non-invasive pulse wave analysis, as described here, depends on different principles and type of the pulse wave. Pulse wave analysis in clinical practice is commonly used by the hand-held tonometry probe. It is simple to use, a non-invasive and accurate method using a small strain gauge sensor detects the force on the artery wall [2]. The principal of applanation tonometry is a partial compression of a pulsating carotid artery against muscle and vertebral body of the neck and its pulse wave spreading in the skin impacts the

Continuous monitoring is required for critical cardiac patients to ensure superior treatment. With the progress in electronic and adhesive technologies several long term wearable ECG monitors have been developed which requires no wires to operate. This emerging technology ensures incredible mobility and maximizes the comfort level for the patient. These monitors can operate as either recorders or wireless streaming devices. As some cardiac diseases have transient and irregular characteristics in ECG performance, long term wireless devices have empowered the physicians to diagnose the patients more precisely. To improve device performance and increase patient compliance several groups have been working on wearable monitors. In this paper, a

Respiratory rate is very important in indicating the progression of illness and predicting the rapid decline in health conditions. Any negligence in monitoring respiration rate or diagnosing respiratory failure can lead to life threatening incidences within a short period of time. Hence nurses and doctors need to be more aware of the importance of an abnormal respiratory rate as a marker of serious illness. To better analyze and interpret the breathing rate, a solution for long-term monitoring is required. Currently used methods involve invasive techniques which are inconvenient for patients and thus not suitable for long term use. Hence in this project, a digital respiration rate meter is designed and developed for better monitoring of respiration rate. This meter is distinguished from other monitoring techniques in the way that it is customizable according to the age and can be used by any person irrespective of his gender and age. Also, it is a low cost device involving simple digital electronics

These sophisticated technologies have given opportunities to many patients to save their lives, these advanced technologies can detect the disease and can provide the treatment with higher accuracy. It makes the specialists work easier by having technology in the medical field.

The MRI – Magnetic Resonance Imaging – is a non-invasive medical procedure that uses a powerful magnetic field and radio frequency pulses to produce detailed images of soft-tissue, organs, blood vessels, bone and nearly all other internal body structures. These detailed images allow physicians to evaluate various parts of the body and diagnose and treat various medical conditions. Unlike X-rays and CT scans, MRI machines produce 3D images of the body without the use of ionizing radiation. The traditional MRI machine is a large cylindrical tube surrounded by a powerful magnet, with the patient situated on an examination table that slides into the centre of the tube. Doctors often use the MRI to view

A person’s heart rate provides a lot of information about their health. However, the heart rate monitors that are used to find the heart rate can be very expensive. Cardiologists at the Wexner Medical Center are interested in a new heart rate monitor that is more cost-effective for use in third world countries. A prototype of the new heart rate monitor was given to FEH students to conduct an experiment. The purpose of this experiment was to tough roughly test the prototype and analysis the differences between different stages of data collection.

Modern medicine has undergone major advancements over the past years. One of these developments include the capacity to retrieve crucial information about the human body and its health beyond the use of manual diagnostic techniques. This is referred to as Medical or Diagnostic Imaging.

The dataset for ECG signals are obtained from MIT-BIH pyhsionet database. There were two databeses present in the website, one was Normal Sinus Rhythm database(NSR), and other was sudden cardiac death(SCD) database. In this database it had one hour of each pateints ECG record, where 30 minutes were prior to cardiac arrest. Every 5 minutes of ECG srignal were used to record HRV, and thus keeping a window size of 10 minutes, HRV values
