25 Replies: 1  Well, first of all, you are not alone. Ha ha, second of all, I don't have an answer for this. 2  Have you been tested for glaucoma. If not get yourself tested by an ophthalmologist, not an optician. 3  I don't think my problem is that serious.... I mean becoming blind.
So, the calculated normal reference value of whole blood viscosity (230 s â 1) of old women in Beijing can be obtained, and it is 4.85 Â± 0.55 (mPa Â· s), the normal reference value of whole blood viscosity is in the range between 4.30 (mPa Â· s) and 5.40 (mPa Â· s).
1 In plasma, the normal ratio of bicarbonate (HCO3-) to carbonic acid (H2CO3) is 20:1. 2  This ratio keeps the blood pH level within the normal range of 7.35 to 7.45. 3  Blood pH becomes more alkaline as the ratio increases (for example, 22:1). pH of 7 is neutral, below 7 is acidic, and above 7 is basic. The pH is defined as the negative logarithm, to the base 10, of the H+ concentration. o pH = -log10[H+]. The normal pH of arterial blood is 7.35 to 7.45.
