Monitoring and recording main physiological parameters with OBCI

in General Discussion

Hi guys,

 

I’m new to biosensing, and need some advice from more experienced community members. My professional area of interest far from Open BCI project, but I had some experience with electronic engineering and simple programming. I’m interested in system for monitoring and recording main physiological parameters like EEG + ECG + blood pressure + video recording. Plus, some kind of alarm system if some parameter will have excessed safe value. I got 16channel OBCI variant and want to use it for my purpose, few question arised:

 

  1. 1)      If there way for easy extracting pulse value from ECG data or I`ll need additional pulse sensor?
  2. 2)    If there any blood pressure sensors which can be hocked up to OBCI board or it will be easier to use separate blood pressure measurement device?
  3. 3)      What kind of software can be used to have all those parameters in one place? (OpenVibe, BrainBay?)

Thanks

    HPPD, hi.

    I havent heard of any blood pressure hookups here on the forum, but there are probably a lot of arduino articles,

    Regarding your pulse questions, some related threads,

    There is a Search box in the bottom right column.

    I should add that I think neuromore now supports Bluetooth heart rate chest straps, such as the Polar H7. So that could give you the EEG plus heart rate / HRV / R-R intervals. If you encode your pressure into one of the aux channels or spare EEG channels, that could be interpreted by neuromore as well.

    And if you wanted to avoid the chest strap, you could still adapt Isa @brain 's BrainBay tutorial to neuromore.

    One of the links above is to Joel's Pulse Sensor ear clip, which can derive pulse info, there's even new firmware that Joel did with AJ Keller.

    Thanks wjcroft for pointing me out,

    Yes I definitely need looks thought arduino variants, there is just one problem - most solution available dedicated for single measurement of blood pressure, but not monitoring. It is nice to have at least one point per second. I not interested in really precise measurement or FDA approved , I saw affordable devices on aliexpress with BLE, triggering start button with timer I probably be able to obtain few point of the data per minute which is fine for now and synchronize with other data later.

    About pulse - pulse detection algorithm for ECG looks fine and probably I`ll try translate that to neuromore. 
    Using chest strap fine for me as well, more over I already have one from Garmin (although not BLE but ANT+).

    Thanks
