CPETlab
Unit 1

The Physiology

Simulated. Idealised curves and a simulator you drive yourself — change a variable, watch the nine panels answer.

Unit 1 is the physiology, on illustrative curves rather than real studies — the only unit where the numbers are chosen to make a point rather than measured from a patient. It says so on every page.
Simulator

The interactive 9-panel CPET

Change a variable and watch all nine panels answer. The engine this whole unit is built on.
