VSS: Improved control-panel for the trainees

In the past, I used a modified keyboard to let the trainees control the Vital Sign Simulator (VSS) defibrillator function. I just put appropriate stickers on the function-related keys (e.g. a red flash-symbol and “SHOCK” on the “enter”-key), and covered the unused keys with a white sheet. A simple, but rather clumsy solution.

To make the controls more compact and easier to use (and give my lazy 3d-printer something to do…), I recently constructed this shiny new control-panel.DSC_7652_1024x678

It is made of the electronic innards of a normal USB-keyboard, some buttons, lots of colorful wires and a 3d-printed housing. See this new section for the detailed description.

Next step will be to take a wireless keyboard apart and build a similar control panel with it. Together with an android tablet and the SpaceDesk-App it will make VSS fully mobile!!!

VSS 1.4.2: Automatic gradual change for HF

Good things take their time…

In the newest version of my Vital Sign Simulator, you can let the program change the heartrate to a target value over  a specific time (0-600 sec). Every 5 seconds the rate will change, every 10 seconds the documentation will be updated. Hope it all works well, the program is becoming more and more complicated with all the additions, sometimes this leads to unexpected complications under certain conditions. So please let me know if you experience problems!

Vital Sign Simulator 1.4.2! Free as always! Download available on sourceforge.net.

Gradual spO2-change for VSS

Vital Sign Simulator newest Version 1.4.0 out now:

Now more hasty clicking every few seconds if your patient is crashing, thanks to this new function: Automatic gradual increase/decrease of the spO2-value over a specific time (choose from 10-600 sec)! Every 2.5 sec the value will change, every 10 seconds an automatic log in the documentation will be made!

I will implement it for every parameter over the next week or so, but couldn’t wait to bring it to you. Have fun and check out version 1.4.0! Free as always! Download available on sourceforge.net.

Alternative to FFsplit for recording simulation sessions: OBS

Due to a prolonged downtime of the FFsplit download-page, I searched and found a good (or even better) alternative for recording simulation sessions: The Open Broadcaster Software.

I am testing it right now on an old pc with three webcams, and it looks good so far. Unlike FFsplit, it is still supported and development is going on.

I will keep you updated and post a OBS-specific installation guide soon.

Vital Sign Simulator updated – again!

I promised you a further Vital Sign Simulator update soon. Soon is now!

VSS goes into version 1.2.0, one more function was added: The CPR-artefact!

Ever been annoyed by trainees interpreting the cristal-clear ECG during CPR without waiting for the break after 2 min? Well, fear no more! By clicking the yellow “CPR Start”-button, the current ECG-rhythm is replaced by a meaningless typical CPR-artefact. Press the button again when CPR stops, and the original ECG will reappear. See the manual for a detailed description.

So check out version 1.2.0! Free as always! Download available on sourceforge.net.

LowCostSim – Medical simulation on a shoestring

Hi there!

This site is currently under construction. Once finished it will provide you with lots of inexpensive tips and low-cost tools related to medical simulation.

Finished sections so far:

  • The LoCo-A/V-System. Check it out these building instructions if you are looking for an inexpensive but powerful alternative to commercial A/V-systems! Quad-split recording, inclusion of vital signs, all based on a simple PC, a few webcams and free software!
  • The Vital Sign Simulator. Free software to simulate a working monitor/defibrillator-unit on your PC. Set an ecg-rhythm, NIBP and so on and let the trainees react to the changes!

I hope to add much more content over the following months, so stay tuned!
