Suggestion to add important health feature to Garmin watch

5029165
over 4 years ago

Dear Garmin

 I do highly suggest to add a new specific  healthy feature to Garmin watch:

Please if you can work it out it's really very important and very benefialy. This feature aim suggesting to add is to measure the acidity or alkalinity of the blood .

The measurement of acidity or alkalinity of human blood is a very good indicator for health therefore adding this features to Garmin will be agree acheavment.

i did suggest this simply because the current Garment features including oxygen blood saturation+ Respiration + heart rate+ stress level+ muscle O2 saturation level: thus it's very possible to work it out to add this very important feature for measurement of acidity and alkalinity of the blood

i hope to consider this very important feature it will be in deed very great to add it at this critical time for facing Corona virus crisis

Kind Regards

Dr Abdull Ramadan

    Yeah, and they can warm up by cleaning up some loose ends they already have, such as the Edge 530 not giving Intense minuets in Garmin Connect, nor syncing with Heat index for overall fitness tracking.  As integrated as they try and make this stuff.. in some ways its still far apart.

    Since measurement of blood pH requires a blood sample and lab analysis... how do you think this could possibly be accomplished on a wristwatch?

    Now this is simple..  all they need to do is make the sensor super sharp so that it pricks the wrist ever-so-slightly.  ;-)

    1.  Blood pH is an important diagnostic  / measurement in a clinical environment for various conditions, see eg https://www.ncbi.nlm.nih.gov/pmc/articles/PMC137247/    (Used to diagnose eg acidosis etc.  Certain out-of-normal pH conditions impacts heart and brain functioning)

    (This should not be confused with the pseudoscience of 'pH by diet' etc)

    2.  Some research are already been done re the potential of optical measurements, see eg https://www.sciencedirect.com/science/article/pii/0250687486800087  ,  https://ieeexplore.ieee.org/document/8075871  (using spectrography etc) This is still in a lab context. 

    3.  With the correct sensors etc, this might actually be a possibility, I think the OP has a very good idea.

    Rubbish.  There is no doubt that there are several methods for measuring blood pH using light and sensors, etc., but all of them are either in vitro requiring the extraction of a blood sample, or in vivo using a surgically implanted sensor.

    In what universe might "this actually be a possibility" for a wrist-worn consumer device?

    The whole idea is scatter-brained pseudo-science which serves no other purpose than to provide fodder for keyboard commandos with no scientific background.

    /Rant off

    Carry on.

    There is already a patent application for non invasive pH measurement https://patents.google.com/patent/US5885212

    'By means of these spectral factors and wavelength ranges, non-invasive measurement of blood pH can be performed using apparatus and methods of the type described in the
    above-referenced U.S. Pat. No. 5,355,880, the relevant por tions of which are incorporated herein by reference. For
    example, the invention can be used to measure arterial blood pH non-invasively by utilizing the pulsatile nature of blood
    flow to address Such patient variables as skin, fat, bone, and muscle absorption, as is done in the measurement of oxygen Saturation by pulse oximetry. pH determination by this approach is a particularly preferred embodiment of the
    invention.'

    Still confident about your in vivo / in vitro only statement?

    Maybe download and read the pdf from iopscience.iop.org/.../859

    This is part of your argument to add this feature?  OK.  Well, you're wrong then.  There is no pending patent.  Check your own link.  The application was submitted on Jun, 13th, 1996.  A patent was never approved and the application has since expired.  It shows today's date under "application events" because that's when you posted the link, but if you scroll to "legal events" you'll see that it expired Jan, 23rd, 2018.  Nearly twenty-two years and the "technology" was never patented.

    Based on the patent application that expired more than two years ago that you posted, I'd say yes.

    It frankly seems inconceivable that the existing sensor array on the F6 could be extended to monitor anything other than HR and SpO2.

    Eventually many many sensors will be added as the technology allows.  Probably the most important would be a blood glucose sensor.  There are several companies trying to perfect a non-invasive continuous glucose monitor (search for "GlucoWatch" for one attempt).

    Some other things that could be done with different sensors in the future:

    • Electrolyte balance for detecting dehydration and hyponatremia (could be somewhat accurate but would require personal calibration for skin resistivity or something similar)
    • Skin temperature (would require a calibrated bottom and top temp sensors and would probably be only marginally accurate)
    • Blood Glucose -- HUGE win if it could be accurate and not require any disposable sensor pads
    • Blood PH might be doable eventually, particularly detecting Ketoacidosis which can be life-threatening in diabetics
    • Parkinsons sensor (since some people can smell it, it seems it could be done)
    • Seizure warning (again, dogs can smell oncoming seizures in some people)
    • Certain cancers

    It was to demonstrate the principle that not only in vivo / vitro is possible even if that specific example is only conceptual. (Did you miss the 'also ref to' statement?)  PS - I did use the same phrase that you yourself are using - 'patent application'.  'Pending patent' is your words.  Was a working model built for verification of the patent application?

    Did you see the other two links not only refuting the in vivio / in vitro only statement, but actually providing and documenting real life tests?  

    Here it is again for your convenience, maybe the titles will give you a clue already:

    https://iopscience.iop.org/article/10.1088/0967-3334/34/8/859  (​​Validation of a spectroscopic sensor for the continuous, noninvasive measurement of muscle oxygen saturation and pH)

    https://www.ncbi.nlm.nih.gov/pubmed/17331316   (​​Noninvasive in vivo measurement of venous blood pH during exercise using near-infrared reflectance spectroscopy. ) 

    Still confident when ref to these two articles?
