a healthy 50 yeal old man who resides at sea level takes a 45 minute ride in a cable car from near sea level to a ski resort ( altitude 3050m {10,000ft} which of the following labeled p[oints on the diagram best represents this pacient 30 minutes afetr arrival at the resort ??
a.-ph 7.2 pco2 (80) HCO3{30}
b.-ph 7.4 pco2 {60} HCO3{34}
c.-ph 7.7 pco2 {30} HCO3 {34}
d.-ph 7.5pco2{30} HCO3{20}
e.-ph7.4 pco2{30} HCO3{16}
f.-ph7.2 pco2{30} HCO3{10}
g.-ph7.0 pco2{20}HCO3{4}
Thanks

D,
There is no renal compensation. So HC03- has to be within normal range.

If you are alkalotic via respiration, it would be up.... how high? I don't think that really matters, just above normal

D fore sure
altitude-->acute hypoxemia (due to decrease in atmosperic pressure)---> respiratory alkalosis--> we narrow choice C and D.
choice C has increase in HCO3 and decrease in PCO2--> mixed alkalosis (respiratory alkalosis and metabolic alkalosis)
choice D: decrease in PCO2 and a slightly decrease in HCO3--> acute respiratory alkalosis.
other choices are:
a.-ph 7.2 pco2 (80) HCO3{30} ACUTE RESPIRATORY ACIDOSIS
b.-ph 7.4 pco2 {60} HCO3{34} FULLY COMPENSATED RESPIRATORY ACIDOCIS
c.-ph 7.7 pco2 {30} HCO3 {34} MIXED ALKALOSIS
d.-ph 7.5pco2{30} HCO3{20} ACUTE RESPIRATORY ALKALOSIS
e.-ph7.4 pco2{30} HCO3{16} FULLY COMPENSATED RESPIRATORY ALKALOSIS OR METABOLIC ACIDOSIS
f.-ph7.2 pco2{30} HCO3{10}: ACUTE METABOLIC ACIDOSIS
g.-ph7.0 pco2{20}HCO3{4} ACUTE METABOLIC ACIDOSIS
