Vent Sim: Ventilator Alarms

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.
