GROUP Physiological reasoning activity 5: High Altitude Adaptations
A healthy student from ASU went to Colorado at the end of the school year for vacation. While there, he drove to the top of Pike's Peak, a very tall mountain. During his first hour on the peak, he walked about but had to sit down to rest three times. The last time was in the weather station. He glanced at the barometer hanging over his head and it read 450 mmHg.
1. Predict the directional changes (increase, decrease, or no change) that would have taken place in each of the listed parameters at the time he entered the weather station compared with values he would have had back at home in Tempe, AZ.
Indicate increase, decrease, or no change for the following:
a. PAO2 (partial pressure of alveolar oxygen in mmHg):
b. PaO2 (partial pressure of arterial oxygen in mmHg):
c. Hemoglobin saturation (%) in his arteries:
d. Hemoglobin saturation (%) in his veins:
e. Tidal volume (VT in mL):
f. PaCO2 (partial pressure of arterial carbon dioxide in mmHg):
g. Red blood cell concentrations of 2,3-DPG:
h. heart rate:
2. What is the name of the medical condition he was experiencing in Colorado?
3. Why is staying hydrated especially important for someone with high blood pressure who is visiting a high altitude location for a week?
