    Estimating Breathing Rate from Respiratory Sinus Arrhythmia

    As a Biomedical Engineer, I’ve always been fascinated by working with physiological signals. It amazes much how much stuff we can measure on the human body and what we can learn from it. Lately, I’ve been missing working with such data. To scratch that itch, I have been busy with a side project focused on estimating the respiratory rate from the heart rate variability signal (measured from single-lead ECG), as shown in the work by Schäfer and Kratky (2008).

    National Instruments University Challenge 2009

    Last week, we obtained the First National Prize in the National Instruments University Challenge 2009 with the project Home Control System for Handicapped People based on Electrooculography. It was a very challenging but also very rewarding experience for all of us in the team: Luis E. Lara-Gonzalez, my colleague and friend, and Prof. Jorge A. Martínez-Alarcon, M. Sc., our professor and advisor.

    Social Service at HRAE Oaxaca

    In Mexico, in order to complete the credit requirements of any undergraduate program, you are required (by law) to perform a so-called social service: 480 hours of non-remunerated work in a nonprofit organization (preferentially in your field). This time corresponds to a half-time service for one semester or a full-time service for one summer. The Biomedical Engineering program at the Universidad Iberoamericana is no exception.

    In my case, I decided for the latter option - summer of 2009. Not only did I chose it because it wouldn’t interfere with my lectures, but this also allowed me doing my social service outside of Mexico City. At first, I thought of the social service as a requirement that I wanted to get done with as soon as possible. I thought I would get the feel of the field work of a Biomedical Engineer, learn one or two new things, and get the credits. I had no clue what kind of experience was before me.
