Blood donation and Hb - measurements (with video)

I used these equipment for the samples and analysis:

- Hemocue B-Hemoglobin (http://www.hemocue.com/index.php?page=5999), user manual (unfortunately only in Finnish) http://www.hemocue.com/files/900149_FI.pdf
- Omon M1 blood pressure measurement equipment: http://www.omron-healthcare.com/sitepreview.php?SiteID=229 (older model than this one).

Blood donation and Hb summary

As it looks like that a tiny hyper compensation has been happened already and values looks like more or less to be stabilized it may time to sum up this test. It looks like that just after the blood donation the whole blood volume drops. Not only Hb level. It also looks like that there may be some compensation mechanisms in the body which tries to keep Hb levels pretty constant just after the donation. Subjectively there is a tiny drop in the endurance but not much. My original hypothesis did not happen as I expected bigger drop in the Hb values as well as in the physical endurance. It was also interesting to see that it looked likthat blood pressure reacted pretty nicely for blood donation. Also sample tests were really difficult to take in the end of the test as it was difficult to get blood form the fingers. I guess this was due a reproduction of the blood trombocytes.

Some testrides with noninvasive O2 meter

I had a nice opportunity to test a noninvasive O2 meter (http://www.artinis.com/index_oxi.htm). This company makes nice invasive O2 metering systems which can be used for metering O2 values at muscle levels thru the skin. For a test ride I was willing to see would there be any difference between postural and non postural muscles (http://en.wikipedia.org/wiki/Muscle) in isometric work.
I checked values from wrist extensors and back extensors. All the measurements was done in 1 minute. No hyperventilation in breath hold.

Here are the results:

​

1. Normal breathing (wrist extensors)
2. Empty lungs breath hold (wrist extensors)
3. Full lungs breath hold (wrist extensors)
4. Hyperventilation (wrist extensors)
5. Normal breathing (lower back extensors)
6. Empty lungs breath hold (lower back extensors)
7. Full lungs breath hold (lower back extensors)

For me there are least 2 observations: wrist extensors looks like to be little bit more sensitive for hypoxia (non postural muscle) compared to back muscle and the back muscle (postural muscle) O2 levels looks to be little lower compared to wrist extensors.

This gives me pretty nice ideas for further tests as well as some practical use. Would it be quite good idea to use more postural muscles for dynamic apnea and constant weight for example?

Blood donation and Hb (day +20, +23 and +25)

Some new values again. Subjective feelings in a training is that hyper compensation is happening. At my case this means that trainings can be done pretty hard but body is getting tired anymore. And it also feels like that most of the previous levels and lenghts at the distances for example feels pretty easy.

Blood donation and Hb (day +18)

Curve seems to be going back to normal. As there may be some tiny facts with erythropoiesis this result may be due some adaptation mechanisms in the body as well as some minor variations at the measurements.
