Abstract Congestive heart failure (CHF) is a leading cause of death in the United States affecting approximately
670,000 individuals. Due to the prevalence of CHF related issues, it is prudent to seek out methodologies that would facilitate the prevention, monitoring, and treatment of heart disease on a daily basis. This paper describes WANDA
(Weight and Activity with Blood Pressure Monitoring
System); a study that leverages sensor technologies and wireless communications to monitor the health related measurements of patients with CHF. The WANDA system is a three-tier architecture consisting of sensors, web servers, and back-end databases. The system was developed in conjunction with the UCLA School of Nursing and the
UCLA Wireless Health Institute to enable early detection of key clinical symptoms indicative of CHF-related decompensation. This study shows that CHF patients monitored by WANDA are less likely to have readings fall outside a healthy range. In addition, WANDA provides a useful feedback system for regulating readings of CHF patients.

    After conducting a few surveys and collecting feedback, there are a few modifications that need to be made. One of the things that the feedback stated repeatedly is that the price of $100 is too much for this product. This can be fixed by lowering the cost gradually to $50. Those providing feedback also expressed concern that this product could be used to avoid going to the doctor or seeking other medical advice from those who are qualified. One thing that could help is having this device connecting online to network and alerting a doctor or hospital depending on the readout. A future addition that should be added based upon feedback would be a voice readout of the information collected. Also needed is a way to save that information to a computer so a doctor is able to review and compare the information to the current stats. These additions could help people to receive the medical care that they…

    In this article, a system was designed and built in order to receive, store, process, analyze, and display heart electrical signal wirelessly on cell phone. This device has small size, light weight, low power consumption, and appropriate price. The doctor or the nurse is able to receive and observe heart signal on their own cell phone only by installing the proper program and loading the related file. This device is also capable to calculate patient’s consumption calories and store the value; and also has a data base consisting of medical and drug information for increasing the awareness of patient about heart diseases. The obtained results from recording and displaying heart signal on cell phone by designed system has an…

    Congestive heart failure is the process in which the heart becomes in-able to maintain circulation for the requirements of the body at an effective rate, As the heart is one of the body’s vital organs, it plays an important role and has some degree of compensating mechanisms to balance the body’s needs with existing disease of the heart. Eventually when the heart is no longer able to compensate heart failure occurs; congestion will then follow, resulting in insufficient supply of blood to the body.…

    Congestive heart hailure, also known as CHF or heart failure, affects the lives of 5 million Americans each year with 550,000 new cases diagnosed yearly. (Emory healthcare, 2013) CHF is a medical condition in which the heart has become weak and cannot pump enough blood to meet the need for oxygen rich blood required by the vital organs of the body, less blood is pumped out of the heart to the organs and tissues in the body and pressure in the heart increases, it does not mean the heart has stopped working. (Murphy, 2013) Once the heart has become weakened by conditions such as hypertension, abnormal heart rhythms, heart attack and heart disease, it leads to heart failure, leaving the patient with a poor quality of life. Patients with congestive heart failure cannot reverse this disease, but they can relieve some of the signs and symptoms of the disease by restricting their diet of fat, cholesterol and salt intake, maintaining a healthy weight, smoke cessation, exercise and stress reduction.

    Congestive heart failure distresses the heart’s function as a pump to meet the body’s needs, affecting many organs of the body including the liver, lungs, kidneys and the intestines. Untreated, this condition will affect virtually every organ in the body. (MedicineNet, 2012) According to Healthline.com congestive heart failure (CHF) is defined as, “A condition in which the heart can no longer pump enough blood to the rest of the body.” (Healthline, 2012) Heart failure is a serious disorder that may get worse with an infection or physical stress. It is often classified as either systolic or diastolic. Systolic heart failure means that your heart muscle cannot pump or eject the blood out of the heart properly. Diastolic heart failure means that your heart’s pumping chamber does not fill up with blood. In both systolic and diastolic heart failure the heart is no longer able to pump enough blood out to the rest of the body. This is especially true when you are active or exercising.

    The cost of exploration and learning are two important factors that must be used in order to help achieve sustainability of a telemedicine practice. Licensing and credentials can be costly even for doctors. So, a telemedicine endeavor must be able to assess the cost and risk of starting a business and be able to foresee its future in educating its doctors and staff. A service model based on the assumptions of what can happen in the market place can help develop a business plan. An appraisal on how much telemedicine education would cost and how much you will actually need for each individual in the practice, can determine what returns it will reap. Risk assessment on the developing market as well as its competitors in the developing market…
