Andrew Shared "HSF Week 04" - 9 Picmonics
With Picmonic, facts become pictures. We've taken what the science shows - image mnemonics work - but we've boosted the effectiveness by building and associating memorable characters, interesting audio stories, and built-in quizzing. Whether you're studying for your classes or getting ready for a big exam, we're here to help.
HSF Week 04
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)

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