Oddly, the poor rapid shallow breathing habits of most people, puffing along at 12 or more per minute when three would better serve, seems to most often result in abnormally low blood CO2 from rapid breathing than high CO2 from shallow breathing.
A respiratory rate of about 10 to 12 is normal. Normal people (without lung disease) will keep their pCO2 VERY close to 40. It's quite unusual for a normal human being to run a pCO2 below 40 in a non-stressed situation. CO2 is a key part of pH control, and the body is pretty darned careful about keeping the pH at 7.4 and the pCO2 normal. Certain disease states perturb that, and stress and anxiety can result in blowing off significant CO2. But to state that people should have a normal respiratory rate of 3 is bad advice, I'm sorry.
I havent been diving for long about a year but my consumption rate when way down when I put a camera in my hand! when i thought about it latter the camera distracted me from thinking about my breathing and i just breath normally.
