Vent Sim: Ventilator Alarms
Bedside troubleshooting drills
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
When the ventilator alarms — what to look at, what to do.
Vent Sim puts you at the bedside. The ventilator alarm is ringing: read the chart, use checks and treatments to find the cause and fix it, then name the cause and review what happened. Each scene takes about 2 minutes, and you can run them again on your own. Works on iPad and iPhone.
It's also a full ventilator simulator underneath:
- Modes: A/C-VC, A/C-PC, SIMV-VC, SIMV-PC, and PSV (with apnea backup ventilation)
- Real-time airway pressure, flow, and volume waveforms that respond immediately to every setting you change
- Alarms for airway pressure, tidal volume, minute ventilation, respiratory rate, and apnea
- Work of breathing (WOB), so you can compare a patient's effort before and after a mode change
- Built-in cases across normal lungs, ARDS (mild/moderate/severe), COPD, and severe asthma
- A Sources screen showing where the app's numbers come from (textbooks, guidelines, papers), and marking which values are design decisions
Free: A/C (volume and pressure control) and PSV modes, the core settings, 3 cases (normal lungs, moderate ARDS, COPD), and 2 training scenes (airway blocked by secretions, circuit disconnection).
One-time purchase unlocks: SIMV (volume and pressure control), advanced settings (inspiratory pause, rise time), the remaining cases (mild and severe ARDS, severe asthma), 3 more training scenes (mainstem intubation, unplanned extubation, tension pneumothorax), and review export (image and data).
One-time purchase — no subscription. Buy it once, use it for as long as you want.
No accounts, no sign-in, and no data collection of any kind — see the Privacy Policy below.
Please note:
- This app is for education only and is not intended for clinical decision-making.
- It is based on a single-compartment lung model and a simplified gas exchange model, so its behavior may differ from that of real patients.
- It does not reproduce the behavior of any specific manufacturer's ventilator. When operating actual equipment, follow the manufacturer's instructions for use.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- Now on iPhone (portrait). The Full Version you bought on iPad also works on iPhone with the same Apple ID
- Training rebuilt. The alarm is already ringing: read the chart, use checks and treatments to find the cause and fix it, then name the cause and review what happened (about 2 minutes each). 5 scenes: 2 free, 3 in the Full Version (mainstem intubation, unplanned extubation, tension pneumothorax)
- Case setup now lets you choose spontaneous breathing: none, weak or strong
- A Home button takes you back to the title screen from the monitor and from each training screen
- The alarm sound now stops while the simulation is paused
- Waveform display fixes
