I have a work project: Design and implement a life function simulator controlled by an Arduino or similar microprocessor. The system must allow simulation of at least 1 ECG lead, simulation of the IBP signal pressure waveform and simulation of blood oxygen saturation SpO2. Each variable shall allow for a change in time domain and a change in amplitude. Test the implemented device with a vital signs monitor. I found several projects on the internet and there were several articles on the forum based on a similar topic. But not everything I would like to see for my projects was there, because I need to see how to set up the arduino and then connect it to the monitor and the code that was written to the arduino. I'm not a master with the arduino so I want inspiration from some full articles.
The work project should be the only inspiration necessary. Have you started on the design?
Little bit yes. I try to creat the first time in Software - Tinkercad and after that if it works to creat physicaly with arduino and monitor.
As I said, unfortunately I'm not directly at programming school, so I only know some basics
That is where I started, also. So many years ago. Mostly on-job-training with added Community College courses.
Do you have any suggestion how to start? Or do you have any ideas about the signal and the hardware?
Those are very vague specifications. "Simulation of one ECG lead" implies generating continuously varying signals in the 500 microvolt to 5 millivolt range, and that alone would be a full time, rather complex task for an Arduino.
Which "vital signs monitor" is to be used to test the setup?
Ask your supervisor for more details on the voltage ranges and signal characteristics required from the simulator device.
You had suggestions ten days ago. Did those two threads not yield inspiration?
OK, I didn't know this could be hard for the Arduino. So that's a question I don't know if they'll tell me, because I want to ask the school if they have it, and if not, try the hospital. And the hospital has several manufacturers of vital signs monitors.
Yes, it can do a bit, but I don't understand the function of the project's 5 lead cell....because when I run the simulation and start moving the potentiometer, it generates some signal, but not in one line. And the second one is better for understanding. But as I already wrote I am a beginner, so maybe I didn't understand some of the tutorials correctly, and that's why I wrote a separate post, so that I could possibly be enlightened about what is going on and how
Hi, @davidosk
Have you looked at this link, admittedly it is a "destructible" project, but should shed some light on your requirements.
Tom.. 
Yes yes. This one i find and try to understand it but I want something else to compare and try use only something which looks like useble.
Then frankly this sounds a bit overambitious.
One possible tactic would be to connect with one or two of these manufacturers, explain you're a student and interested in how to simulate vital functions for testing the kind of equipment they make. If you're lucky, you may get to the point where you can chat with an engineer for a bit so you can understand what's involved in making these kinds of simulators. Odds are that at that point, you'll walk away from the project, but at least you'll have some backing towards your supervisor and/or project team for the observation that they've set you an unrealistic goal.
In short, go back to whomever gave you this assignment and re-negotiate.
The simulation that I linked to is not able to output a waveform... it only accepts an analog input and places it on an OLED.
yes.
1: Do a project plan.
2: Find the easiest thing you can do to make progress towards the goal

Neither does your supervisor, evidently. Go to that person and discuss the actual expectations, in light of the difficulties that Arduino forum members have pointed out.
