A manikin that breathes, blinks and changes its own vital signs is a wonderful teaching tool. It is also expensive, booked solid, and tied to one room. Most of what students need from the monitor, though, is simple: numbers and a rhythm that change when the patient changes, so they have something to notice, interpret and act on.
You can give them that on any screen.
What a monitor adds to a simulation
A scenario on paper tells students the heart rate is 118. A monitor makes them find it, and notice when it becomes 132. That is the first step of clinical judgment: recognizing cues. A live display also lets you teach things a static handout can't:
- Trends. A blood pressure of 94/58 means one thing if it was 122/76 ten minutes ago and another if it has been stable all day.
- Timing. Students learn how long they have. If nothing is done, the numbers keep moving.
- Cause and effect. After the right action, the numbers recover. After a missed one, they don't.
- Rhythm recognition under pressure. Naming ventricular tachycardia on a quiz is different from seeing it appear while you are doing something else.
A free monitor you can open right now
MapMySim's vital signs monitor is free for anyone at mapmysim.com/monitor. There is no sign-in and nothing to install. It shows:
- a moving heart rhythm with the heart rate
- SpO2 with a pulse waveform
- respirations, with EtCO2 and a capnography waveform when you turn it on
- blood pressure with the mean arterial pressure
- temperature, in Celsius or Fahrenheit
The rhythms are sinus rhythm, atrial fibrillation, SVT, ventricular tachycardia, ventricular fibrillation and asystole.
How to set it up for a case
- Make one stage for each point in your case. A common set is baseline, early decline, critical, and after treatment. Give each stage a name and its vital signs.
- Choose how fast the numbers change. "Change over" sets how long the monitor takes to drift from one stage to the next, from right away to two minutes.
- Decide what students see first. You can keep a reading off the screen until students attach it. Hide SpO2 until the probe goes on, or EtCO2 until capnography is applied.
- Run it your way. Tap a stage when students do (or miss) the key action, or press Play and the monitor runs through the stages by itself, like a video, staying on each one for the time you set.
- Change anything live. If a student gives oxygen early, raise the SpO2 right then. Every number and the rhythm can be edited while the monitor is running.
Hide the controls and switch to full screen for the student view. To change the monitor from across the room, get a code on the classroom screen and enter it on your phone.
Ways to use it
In the sim lab. Put it on a tablet or TV at the head of the bed, next to a standardized patient, a low-fidelity manikin or a task trainer.
In the classroom. Project it during an unfolding case study. Pause at each stage and ask what students notice, what it means, and what they would do first.
In a student case presentation. Students presenting a case can show the patient's course instead of reading numbers off a slide.
For skills check-offs. Use one stage with one abnormal finding and ask students to find it and report it.
For EMS classes. EMT and paramedic students can practice reassessment: take a set of vitals, treat, and see whether the patient responded.
Loading the vitals from a scenario
If you build your scenarios in MapMySim, you don't have to type the vital signs twice. Each scenario has a Vital signs monitor button that opens the monitor with every stage of that scenario already loaded, and each stage has its own button to jump the monitor to that point. MapMySim drafts a complete scenario (objectives, prebrief, patient stages, orders and labs, debrief and rubric) for nursing courses, and now for EMT and paramedic classes, for the instructor to review and make their own.
A note on safety
The monitor is a teaching display. It is not a medical device, it does not measure anything, and it must never be used for patient care. The rhythms are simplified drawings meant for recognition practice, not diagnostic-quality tracings.
The short version
Students learn to read a changing patient by watching one change. A free monitor on any screen gives you that without a high-fidelity manikin: set a few stages, decide the pace, and let the numbers tell the story.
