Shows how the A–a gradient compares oxygen in the alveoli with oxygen in arterial blood to help localize hypoxemia, from low breathing or low inspired oxygen to V/Q mismatch, diffusion problems, or shunt. Click a mechanism, or enter age, FiO₂, barometric pressure, PaCO₂, and PaO₂ to calculate the gradient and see whether it is normal or elevated.
