"Do Total intravenous anesthesia TIVA with your cellphone and volumetric pumps, in a pharmacokinetic manner"
iTIVA is a simulation program that provides information about distribution of drugs based on mathematical models (Minto, Schnider, Marsh, Shafer, Scott, Gepts) for remifentanil, fentanyl, sufetanil, propofol and dexmedetomidine.
Based on those models, iTIVA calculate a dose required to achieve a desired target, plasma or effect site, like a TCI pump (target control infusion), generating schemes that can be implemented in volumetric infusion pumps, and thus perform total intravenous anesthesia (TIVA) based on pharmacokinetics principles.
It also calculate the end tidal (Et) for Isoflurane, Sevoflurane, Desflorane to get the MAC age based in the Mapleson formula or Lerou normogram.
iTIVA simulates the behavior of a TCI pump, calculating different infusion rates to achieve an effect site concentrations. When it placed in real time mode, iTIVA notifies when to make changes to the infusion.

iTIVA is not designed to handle intravenous drugs for individual patients. Its use is limited to educational purposes to demonstrate pharmacokinetic principles when performing intravenous anesthesia. Therefore the user assumes all risks from the use of this application for clinical purposes.
Infusion schemes are obtained from concentrations based on models published in the medical literature; therefore concentrations achieved from these schemes can vary widely, in the same manner for clinical effects.
This application should only be used by people with extensive knowledge in Anesthesiology.
