Assignment:
Brandon is a 40 years old runner who experienced severe dehydration after his marathon race, leading to hypovolemia and hypotension.
Following a month of rest to recover from his ordeal, he went to the gym to undertake some light exercise and regain his fitness under the guidance of an exercise physiologist.
Before going to the gym, a set of vital signs were collected. Results are: RR 14 bpm, SpO2 95%, BP 130/70 mmHg (Mean arterial pressure 90 mmHg), HR 74 bpm.
Collect cues:
After the first round of exercises, they check his vital signs again.
His respiratory rate is now 20 bpm, his SpO2 is 95% on room air, BP is 140/80 mmHg (Mean arterial pressure 100 mmHg), and HR is 90 bpm. He is observed to be breathing deeply and heavily.
1. Explain the physiological mechanisms during normal pulmonary ventilation, including the structures involved, and volume and pressure changes.
2. Brandon's SpO2 is still 95% at room air after exercise, describe the possible factors that may influence the efficiency of his pulmonary gas exchange, thus impacting his oxygen saturation.
3. While Brandon was running on the treadmill, his muscle tissue produces CO2 as a by product of ATP generation. Describe how the majority of CO2 is transported from the tissue to the lungs to be expelled.
