Introducing CloudTimer.app
Have you conducted a viva or osce examination? My friend Eric and I wrote this app to help synchronize the countdown timer - this web app is a cloud-connected timer, so that the host can control a timer session and multiple viewers can connect to it simultaneously.

December updates - Simtiva.app:
(1) Infusulator, a retrospective data entry tool to simulate the infusion data from time series of CP/CE target values.
(2) Live preview for manual mode. The graph will be plotted as you type in the bolus or infusion values so you can preview the change in real time

Upcoming feature: live preview of bolus/infusion rate change in manual mode.
Sometimes, we need to change our inf rate or give an extra bolus, SimTIVA now plots the curve for the predicted changes dynamically as you enter your values. Video demo of "live preview" of reducing inf rate from 50 to 30

"Infusulator", first created by Matthew Hart, coming soon to SimTIVA. It allows easy entry of a time series of CE (or CP) targets to generate TCI simulations. The conversion from CET/CPT to dosage (volume infused, or the total dose) over time is made simple. An export module is also provided.

Total intravenous anaesthesia (TIVA) for rapid sequence induction (RSI)
Worried your TIVA infusion is too slow for RSI?
Why not work with your local manufacturer to develop an ‘RSI-TCI’ mode for your target-controlled infusion pumps?

"... a ‘RSI–TCI’ mode with a pre-programmed manual bolus offers a pragmatic solution for those who wish to preserve an intact pharmacokinetic model for accurate propofol delivery, while allowing the rapid induction clinicians expect from a manual bolus."

Today I have updated simtiva.app and simtiva.vet -
The changes are mainly visual, with a refreshed look. Part of the reason is user feedback regarding the new iOS 26 on iPhones partially breaking the user interface with malpositioned top and bottom elements.
Minor bugfixes as well.

Ketamine (Kamp) model will be improved soon. On Simtiva, the Kamp model used a ke0 of 0.238, from Navarette PD study using ANI index (ref1). However, that PD study applies to the Domino PK set, and ke0 is model-specific and should not be naively applied to another PK model...

Low-dose ketamine infusion is an excellent component of multi-modal opioid-sparing analgesia. Kamp model uses meta-analytical technique to facilitate better plasma site targeting for TCI ketamine. This model is now introduced in SimTIVA.app

Happy to share that Simtiva (veterinary version), a TIVA simulator for small animals, was successfully used to guide TIVA in prolonged surgery in a cat, and the results were recently published in VAA journal.
Simtiva.vet was co-developed by Enzo Minghella & me 1 yr ago and is actively updated.

SimTIVA.app is fully capable of offline support. The app can be run offline. Internet connection can be unstable sometimes, but rest assured you can still run SimTIVA normally. Also, minor changes to the mcg/kg/min default rate unit display (manual mode) for Propofol, the bug is fixed.

You've been meaning to get around to reading about the differences between adult TCI models for propofol? On the to do list for .... ever??
Listen to this to get you warmed up, and check out the references in the show notes for the in depth excitement you're desperate to have!

The term "TIVA RSI" misrepresents the issue.
All RSIs are IV. Whether it's a TIVA anaesthetic depends on whether the subseq maintenance agent is inhaled or IV (& irrelevant to the process of RSI).
The question is whether IV induction agents should be administered by an infusion pump during RSI.
