Post-Dilutional Hematocrit Calculator
Lactate lever: low Hct lowers O₂ delivery (DO₂) and drives lactate up.

Perfusion Toolkit — general dosing utility (heparin, protamine, cardioplegia). Not part of the lactate score. Doses are typical ranges — verify against your institutional / surgeon protocol.

Patient Type
Cardioplegia
Cardioplegia type affects myocardial (coronary-sinus) lactate, not the systemic lactate score. Its only systemic effect is via hemodilution — large crystalloid volumes lower Hct (see the Hct & Blood tool).
