Perfusion Nexus, a heart-lung-machine simulator

Field notes

The simulator models a cardiopulmonary bypass workflow rather than presenting a generic quiz: the listed controls include pump flow, reservoir, VAVD, sweep, FiO₂, temperature, clamps, and sucker routing. Its physiology layer names ACT drift, AT-III resistance, cardioplegia phases, ABG variables, DO₂, O₂ER, and NIRS. The free tier contains a routine CABG scenario, while the stated Pro tier adds cases such as ECMO and DHCA, crisis events, cell-saver processing, pacemaker modes, and pump-run export.
