Some mountain climbers will take a medication, called acetazolamide (trade name Diamox), starting 24 hours prior to ascending to elevation as a preventative to reduce high altitude sickness. To figure out how this alleviates high altitude sickness, answer the following questions.

1. Around 70% of CO2 is transported in the blood as bicarbonate ions. Draw this reaction.
2. Acetazolamide inhibits the enzyme that catalyzes the reaction between CO2 and H2O and the dissociated ions of carbonic acid (bicarbonate and H+). What effect would this have on blood pH, blood PO2, and blood PCO2?
3. Acetazolamide triggers the kidneys to excrete bicarbonate and increase the respiratory rate. What effect would this have on blood pH, blood PO2, and blood PCO2?
4. Based on these answers, how does this help to prevent high altitude sickness?

If you friend (Brittnay) came up to you and started talking about brad the chess club captain. A few minutes into the conversation, she starts to hyperventilate at the thought of talking to brad and gets dizzy and confused. But in typical, Brittnay fashion she doesn't stop. To help her out of her stupor, you have several options. You have several options that may or may not help, so please explain how each option can either help or hurt her Co2 levels, O2 levels, acid-base status, etc.

and explain each answer as if you are talking to Brittttnaaaaay.
