Medical equipment risk assessment is part of an overall medical equipment management program for a healthcare facility or system. A complete program includes corrective maintenance or repair, equipment control, asset management, health care technology planning, education, and activities directed toward improving medical device-related patient safety. The purpose of this paper is to provide some guidance lines in establishing and managing a medical equipment quality assurance program and to present some procedures for inspection, maintenance, evaluation, and performance testing for some medical devices. A computerized medical equipment management system is described. The results demonstrate that it is a useful tool in tracking device inventory and maintenance history. Also risk classes have been designed for medical devices based on the time of testing, risk must be identified in relation to patient and staff member. The results of this paper take into consideration the advances in device reliability, reduced preventive maintenance requirements, and internal device surveillance (self test) along with changes in standards.

Medical technology is by now an integral part of health care according to consisting general accepted standards. The Medical Equipment Management Plan defines the mechanisms for interaction and oversight of the medical equipment used in the diagnosis, treatment, and monitoring of patients. The related policies and procedures govern activities from selection and acquisition to incoming inspection and maintenance of medical equipment. The mission is to ensure that equipment used in patient care is safe, available, accurate, and affordable.

Electrical impedance method has found utility in many fields of medical research, but the old instrumentation can be expensive to use and complicated to build. Advancements in electronic component design and equipment allow a bioimpedance analysis using a simple medical device. The aim of this work is to design a medical device which estimates the blood flow and calculates some hemodynamic parameters on the plethysmographic wave. We designed an equilibrated bridge designed on a small circuit board with connections for power and bioimpedance electrodes. A programmable function generator and an oscilloscope were connected to a computer and were tasked to drive and receive data from the circuit. The alternating - current generator is the current source; a series resistor limits the amount of current that passes through the subject. The frequency of the delivered current is between 20 kHz and 250 kHz. Because the skin impedance increases at higher frequencies, a small amount of energy will be delivered to the patient, that ensuring the safety of the system. The circuit was validated by testing its current output over a range of frequencies and comparing measured values of impedance across a test circuit to expected values. The software receives data and inserts it into a data sheet for analysis.

Myocardial ischemia is a pathophysiological state characterized by inadequate perfusion of the myocardium, resulting in an imbalance between myocardial oxygen demand and supply. It is most commonly caused by coronary artery disease, in which atherosclerotic plaques lead to luminal narrowing and reduced blood flow to the heart. Myocardial ischemia can manifest as angina pectoris or silent myocardial ischemia and can progress to myocardial infarction or heart failure if left untreated. Diagnosis of myocardial ischemia typically involves a combination of clinical evaluation, electrocardiography and imaging studies. Electrocardiographic parameters, as assessed by 24 h Holter ECG monitoring, can predict the occurrence of major adverse cardiovascular events in patients with myocardial ischemia, independent of other risk factors. The T-waves in patients with myocardial ischemia have prognostic value for predicting major adverse cardiovascular events, and their electrophysiological heterogeneity can be visualized using various techniques. Combining the electrocardiographic findings with the assessment of myocardial substrate may offer a better picture of the factors that can contribute to cardiovascular death.

Remote monitoring of chronic diseases can improve health outcomes and potentially lower health care costs. The present work refers to the data transmittance and processing, as it is to be implemented in an eHealth monitoring system dedicated to pregnant women with chronically diseases. Alongside a software application and correspondent hardware, it provides an integrated solution of monitoring the evolution of the disease in order to optimize the treatment. The system is designed to be an efficient and safe instrument that transfers the data from different measurement devices towards the medical staff in order to keep update the patientpsilas data and increase the efficiency of the disease management.
