About Monitor Simulator

We are two people in Sweden: an anaesthesiologist who runs simulation training, and a developer. We built the simulator because the monitor was always the weak point in our own scenarios.

Why we made it

Most simulation rooms have a decent manikin and a poor monitor. Either it is a laptop running vendor software that only works with one manikin, or it is a printed card with numbers on it, or someone calls out the values. None of that looks or behaves like the screen a team watches in a real resuscitation.

A tablet is already in most departments, and so is a phone. Turning those two into a monitor and a remote control was the cheapest way we could think of to make every scenario look right.

How it was checked

The anaesthesiologist reviewed every rhythm and waveform against what a real bedside monitor shows and asked for changes until they matched. A few examples of what that meant in practice:

• Atrial flutter is drawn 2:1, with flutter waves at twice the ventricular rate, because that is how it usually presents.
• The pleth gets worse with low blood pressure, not with low saturation. A hypoxic patient with good perfusion has a clean trace.
• PEA keeps its heart rate on the screen. Blanking it would make the rhythm impossible to teach.
• Values glide to their new level, and the heart rate moves faster than the pressure, the way a bleeding patient compensates.
• The eFAST loops were recorded by our anaesthesiologist, normal and pathological.

Why it is free

It costs us very little to run, and we would rather have it used in a hundred simulation rooms than sold to three. There are no accounts and no patient data of any kind. We count anonymously which features get used, so we know what to improve next.

Who we are

We are not using our names yet, while our employers look at the project. In the meantime, the work should speak for itself: open the app, put a patient in VF, and judge.

Tell us what is missing

Many of the features came from feedback after real training sessions. If you need a rhythm, a waveform or a function the app does not have, use the "Missing something? Tell us" link on the app's start page. It goes straight to us.
