Almost anything devoted to CO2 scrubber design for scuba can be applied to
1ATM submersibles.  There's a lot of information on the web regarding scuba
life support.  You can also download a powerpoint presentation I gave at the
2005 PSUBS convention on scrubber design for 1ATM vehicles.  Go to
http://www.psubs.org, click on Design Guidelines, look for "MS Powerpoint
Presentations", and click on "CO2 Scrubber Design".

Hi Thomas,

Always good to know the norms, below is a normal arterial blood gas.
Hypercapnia is the medical term for your question, here's a link describing
scenarios and symptoms.

http://en.wikipedia.org/wiki/Hypercapnia


Arterial blood gases (at sea level and breathing room air)

Partial pressure of oxygen (PaO2):
	70?100 millimeters of mercury (mm Hg)

Partial pressure of carbon dioxide (PaCO2):
	35?45 mm Hg

pH:
	7.35?7.44

Bicarbonate (HCO3):
	21?28 milliequivalents per liter (mEq/L)

Oxygen content (O2CT):
	15%?23% (15?23 milliliters [mL] per 100 mL of blood)

Oxygen saturation (O2Sat):
	95%?100%
