Hemoglobin
- Hemoglobin Has Four Iron Hemes
- Lots Of Hemoglobin In Red Blood Cells
- High O2 Levels Increase O2 Binding
- High Temperature Reduces O2 Binding
- High CO2 Levels Reduce O2 Binding

Physiologic Dead Space (VD)
- Tidal Volume (VT)
- Partial pressure of arterial CO2 (PaCO2)
- Partial pressure of CO2 in expired air (PECO2)
- VD = TV x (PaCO2-PECO2) / PaCO2
2 mins
Alveolar Gas Equation
- Equation
- Partial Pressure of Alveolar Oxygen (PAO2)
- Partial Pressure of Oxygen in the Inspired Air (PIO2)
- PIO2 Normally Approximated = 150 mmHg
- Arterial Partial Pressure of CO2 (PaCO2)
- Respiratory Quotient (R)
- R Normally Approximated = 0.8
- PAO2 = PIO2 - (PaCO2/R)
1 min
A-a Gradient

- Partial Pressure of Arterial O2 (PaO2)
- Normal 10 to 15 mmHg
- Hypoxemia with an Abnormal A-a Gradient
- Diffusion problem
- Shunting (Low V/Q)
- Dead space (high V/Q)
