Aims:
To assess the effects of carbon dioxide (CO(2)) in champagne on psychomotor performance and blood-alcohol concentration (BAC).
Methods:
Twelve subjects consumed ethanol (0.6 g/kg body weight) served as champagne or champagne with the CO(2) removed, in a crossover study.
Results:
Champagne produced significantly greater BACs and significantly increased reaction times in a divided attention task, than degassed champagne.
Conclusions:
The CO(2) in champagne may accelerate absorption of alcohol, leading to more rapid or severe intoxication.

Carbon Dioxide Transport in the Blood
Forms of CO2 Transport
1. Dissolved in plasma: A small percentage (7-10%) of CO2 is transported and dissolved directly in the plasma.
2. Carbaminohemoglobin: Just over 20% of CO2 is chemically bound to...

First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).
Next, the PCO2 and...
