Study Notes
Oxygen Transport
- In anaerobic methods, glucose is used for energy production, and no oxygen is used
- Oxygen binds with the heme group of Hemoglobin (Hb)
- Arterial blood has a high oxygen saturation level of 95-100%
- Venous blood has a lower oxygen saturation level of 70%
Oxygen Saturation Measurement
- Pulse oximeter is used to measure Hemoglobin (Hb) oxygen saturation
pH Levels and Oxygen Transport
- Acidosis: a state of low pH level, leading to decreased oxygen pick-up from the lungs due to an increase in H+ ions
- Alkalosis: a state of high pH level, increasing the likelihood of oxygen pick-up from the lungs
Carbon Dioxide Transport
- Decreased ventilation leads to CO2 retention, resulting in acidosis (high acid)
- Increased ventilation leads to more CO2 release, resulting in alkalosis (low acid)
