Acid production

Daily production of CO2

VO2 = 250 ml/min

R = 0.8

--> VCO2 = 200 ml/min

Thus,

Daily production
= 0.2 x 60 x 24
= 288 L/day
= 12.857 mol/day

(22.4L = 1 mol under STPD)

Net acid production

• ~12 mole of CO2
• 0.1 mol of fixed acid
• 1.5 mole of lactic acid
  * Metabolised by liver
  * Does not actually contribute to net acid production if liver metabolism is normal

NB:

• Acid turnover much greater (at least 200 mol/day)
