## What is Vent Sim?

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. There are 21 scenes: 12 where an alarm is ringing (about 2 minutes each) and 9 you fix by changing the ventilator settings, 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 3 training scenes (airway blocked by secretions, circuit disconnection, hypoventilation in Guillain-Barré syndrome).

One-time purchase unlocks: SIMV (volume and pressure control), advanced settings (inspiratory pause, rise time), the remaining cases (mild and severe ARDS, severe asthma), the other 18 training scenes (10 alarm scenes such as mainstem intubation, unplanned extubation, tension pneumothorax, cuff leak, and a misplaced tracheostomy tube; 8 scenes you fix by changing ventilator settings, covering ARDS, COPD, asthma, postoperative atelectasis, and more), 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.

## Version history (last 5 releases)

### 1.6.3 — 2026-11-11

• Case setup: buttons you can tap (sex, height, settings) are now easier to tell apart, and adjustable values show a marker on the right
• Case setup: button sizes and spacing were rebalanced for a cleaner screen

### 1.6.2 — 2026-11-09

• Renamed the app "Vent Sim: Ventilator Simulator"
• On the title screen, Training is now the main button; the simulator starts from the button next to it (below it on iPhone)

### 1.6.1 — 2026-11-06

• Fixed the Low minute ventilation and Low VTE alarms, which could sound in PC modes even when the delivered volume was adequate
• In Training, the red alarm banner now shows only the alarm name
• In some Training scenarios, adjusted the vertical axes so the airway pressure and flow waveforms are no longer clipped or too small to read

### 1.6.0 — 2026-11-03

• Training now has 21 scenarios instead of 6 (3 free, 18 in the full version)
  - Alarm scenarios: secretions on PC and PSV, mainstem intubation after repositioning, tension pneumothorax during asthma treatment, bronchospasm, cuff leak, a misplaced tracheostomy tube, and more
  - Scenarios you fix by changing settings: ARDS (large tidal volume, too little PEEP), air trapping in COPD and asthma, flow starvation, an insensitive trigger, hypoventilation in Guillain-Barré syndrome, postoperative atelectasis, and more
• New treatments: inhale a bronchodilator, measure cuff pressure and add air, insert a bite block
• Added a patient with a tracheostomy
• The Sources screen now lists the book chapters and pages behind each scenario's key points

### 1.5.0 — 2026-10-27

• New training scenario you fix by changing ventilator settings (full version): "ICU day 3, oxygen saturation drifting down" (hypoxemia in ARDS). Adjust the settings to keep SpO2 at 92 or higher for 1 minute, and use "Wait and see" to advance time and check (up to 15 minutes).
• The training screen now shows the patient and arterial blood pressure (ABP). Tap the tags on the patient to observe.
• Redesigned the chart, observation and debrief screens in training.
