It includes a bit of history, as well as analysis of around 150 existing programs in the region. Results of the different approaches are also included.

Analysis of the Unsuccessful Efforts to Design & Construct Invasive Mechanical COVID-19 Ventilators in Mexico: Did the Current BME Curricula at Mexican Universities Contribute to the Failure?

Mexico was caught unprepared to deal with the current COVID-19 pandemic. One of the most egregious failures was the incapability to provide an additional 10,000 ventilators in order to cope with the excess demand. The Mexican government proposed a program for funding the development of these devices and over 100 designs were submitted but were of below standard quality and performance.

Updating the Biomedical Engineering Curriculum in Latin America: Moving from management and maintenance to Design and Development of Medical Devices.

Biomedical Engineering as an undergraduate degree in Latin America is not new. However, most programs have the objective to produce professionals dedicated to the management and maintenance of health care technology. We believe that there is an important area of opportunity in the education of engineers who are competent in the design and development of medical devices.

Improved Outcomes in Hemodialysis/Hemodiafiltration Treatments Applying Exercise and Physiological Monitoring Techniques: Preliminary Results.

End-stage renal disease affects millions of people worldwide, and the only definitive solutions are renal transplants that are not widely available. Temporary solutions are renal replacement therapies such as peritoneal dialysis, hemodialysis and hemodiafiltration. These therapies as they are applied today are just partial measures and have many drawbacks and complications such as high mortality rates and high costs due to the use of supplemental drugs and emergency room visits.

Critical assessment and outlook for the 50 biomedical engineering undergraduate programs in Mexico.

Biomedical Engineering (BME) has been taught in Mexico at the undergraduate level for over forty years. The rationale for the introduction of this profession was to help manage and maintain the growing technological infrastructure in the health care system during the seventies. Owing to this, it is not surprising that early versions of the BME curricula were oriented towards clinical engineering and medical instrumentation.

Biomedical Engineering curriculum at UAM-I: a critical review.

The Biomedical Engineering (BME) curriculum at Universidad Autónoma Metropolitana (UAM) has undergone at least four major transformations since the founding of the BME undergraduate program in 1974. This work is a critical assessment of the curriculum from the point of view of its results as derived from an analysis of, among other resources, institutional databases on students, graduates and their academic performance. The results of the evaluation can help us define admission policies as well as reasonable limits on the maximum duration of undergraduate studies.

VO2 and VCO2 variabilities through indirect calorimetry instrumentation.

The aim of this paper is to understand how to measure the VO2 and VCO2 variabilities in indirect calorimetry (IC) since we believe they can explain the high variation in the resting energy expenditure (REE) estimation. We propose that variabilities should be separately measured from the VO2 and VCO2 averages to understand technological differences among metabolic monitors when they estimate the REE. To prove this hypothesis the mixing chamber (MC) and the breath-by-breath (BbB) techniques measured the VO2 and VCO2 averages and their variabilities.

Managing new directions for a 38 year old undergraduate BME program.

The Biomedical Engineering curricula in general must reflect the state of the art in the technology related to medicine and health care, as students who graduate from these programs are directly related to the well-being of the patients, either through new devices and technologies being invented or through the application of their technical knowledge in the service industry. At present, there are more than 25 BME undergraduate programs in Mexico. Most of them are oriented towards the instrumentation and clinical engineering branches of the field, while a few others have strong components in signal analysis.

Analysis of the impact of medical technology assessment subjects on BME curricula.

This paper presents and analyzes the factors that have arisen on the implementation of the medical technology assessment and management courses, and the academic methodologies used to deal with them. Five courses that cover topics as Technology Management, Health Economics, Quality Assessment, Innovation and Entrepreneurship were designed as electives for BME curriculum and have been taught for the last two years. The activities carried out within the courses are described and their impact on the comprehension of the course contents are presented.

Updating the biomedical engineering curriculum: Inclusion of Health Technology Assessment subjects.

This paper describes the work being carried out at Metropolitan Autonomous University (UAM) in Mexico City with regard to the continuous evaluation and updating of the Biomedical Engineering (BME) curriculum. In particular the courses regarded as part of the BME basic branch are reduced and new sets of elective subjects are proposed in order to bring closer the research work at UAM with the subjects in the BME curriculum. Special emphasis is placed on subjects dealing with Health Technology Assessment (HTA) and Health economics, as this branch of the BME discipline is quite promising in Mexico, but there are very few professionals in the field with adequate qualifications.

Imaging facilities for basic medical units: a case in the state of Guerrero, Mexico.

This work presents the methodology to design a small imaging unit in a small regional hospital that takes into account the real imaging needs in the region regardless of current administrative guidelines. The situation of the imaging facilities in Mexico's states is studied and compared with other countries, and a project plan is designed for the specific state (Guerrero) where the clinic is to be located. The proposal includes the acquisition of a basic suite of modalities that include an ultrasound system, a mammography unit, and a conventional X-ray system in addition to a CT system that is not available anywhere within the state.

Knowledge network for medical technology management in Mexico.

Objectives: The role of biomedical engineers (BMEs) has changed widely over the years, from managing a group of technicians to the planning of large installations and the management of medical technology countrywide. As the technology has advanced, the competence of BMEs has been challenged because it is no longer possible to be an expert in every component of the technology involved in running a hospital. Our approach has been to form a network of professionals that are experts in different fields related to medical technology, where work is coordinated to provide high quality services at the planning and execution stages of projects related to medical technology.

A digital programmable telemetric system for recording extracellular action potentials.

This article describes the design and preliminary evaluation of a small-sized and low energy consumption wearable wireless telemetry system for the recording of extracellular neuronal activity, with the possibility of selecting one of four channels. The system comprises four radio frequency (RF) transceivers, three microcontrollers, and a digital amplifier and filter. This constitutes an innovative distributed processing approach.

Methodology for the design of a PACS in a small provincial hospital.

This paper describes the design and implantation issues for a Picture Archiving and Communications System (PACS) in a 60-bed provincial hospital. Considerations such as the state of the imaging equipment, preventive maintenance, use and misuse of the equipment and the difficulties regarding migration to an all-digital imaging unit are discussed, as well as the criteria for the selection of the imaging modalities. Finally a design is proposed with four imaging modalities that use open-source database and display workstations.

Analysis of the medical imaging services at three hospitals of the Mexican National Health System.

We present a study on the quality of operation and the characteristics of the medical imaging equipment in three specialty hospitals of the Mexican Health System. Six month residencies were carried out in order to better understand the problems and internal functioning of the three imaging departments. The kinds of equipment, the types of equipment failures and the internal operation of these services were analyzed.

New continuing education programs for hospital and clinical engineering.

This paper describes the new continuing education efforts that are being made to offer degrees more in tune with the career path for clinical engineering or for engineers working at different hospitals. Following an analysis of the issues regarding the field of hospital engineering in Mexico, and the type pf professionals that provide this service, we have implemented a series of programs in order to provide a full spectrum of educational opportunities in biomedical engineering. Since the conventional research-oriented graduate program is doing well, and the number of faculty that is interested in clinical engineering is growing, we now offer professional development track for engineers working inside the hospital environment.
