The person being tested is asked to sit down. They are then asked to "Take a deep breath, and hold it as long as you can." The result, in seconds, is recorded. The respiratory rate rate-(breath hold/5) is also recorded. So if the respiratory rate is 16 and the breath hold is 60, we get 16-(60/5), or 16-12, or 4. This is the pH index (not exactly the same as pH, but it is a number that you can easily calculate and it gives you accurate information on the acid-alkaline balance of the blood). The normal pH index is 7 a pH index of 8 or more would be on the acid side. An index of 7 or less is alkaline. A ketogenic person will often have an index below zero. This is opposite to pH which more alkaline as the number goes up. The pH index is the only practical way for most people to find out what their pH balance is. Urine and saliva pH cannot give this information.
