6. Dry ice (solid CO2) can be an asphyxiation hazard in confined spaces because it can raise the CO2 content of the surrounding air. You are in an environment in which the air is 3% CO2 at 760 mmHg. (a) (4) If the partial pressure of CO2 in deoxygenated blood is 46 mmHg, estimate the decrease in the transfer rate of CO2 from blood to alveoli in regular air (assume 0% CO2) vs. air with 3% CO2. (b) (2) What would happen to the pH of your blood after some time in this environment
