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.

About

TEE Simulator 3D

Features
Read full description

Explore cardiac anatomy with a 3D heart and a synchronized model section. TEE is also known as TOE. This educational app is designed for medical professionals and learners. The free mode includes a beating heart and 28 selectable TEE view presets. An optional, user-initiated 7-day preview unlocks manual TEE probe controls. It does not convert to a paid purchase automatically. The heartbeat and view presets remain free afterward. One-time purchases unlock TEE, TTE & ICE, or all three modes together at a bundle price. TEE adds cycle pause and scrubbing, manual probe controls, transparent walls, valve-focused study, additional vascular views, and local save and resume. Its valve study connects mitral, aortic and tricuspid leaflets and commissures with the surrounding chambers and vessels. The TTE mode offers 12 anatomical view presets with probe tilt, rock and limited slide controls. ICE offers eight right-atrial view presets with catheter controls. These modes are illustrative prototypes for anatomy learning. A free index links to official guidelines on valves and cardiac function. The app can be switched among English, Japanese, Spanish, Simplified Chinese and Traditional Chinese. Models and saved study states work offline; purchases, restoration and external references require internet access. No subscription or app-specific account is required. The sections and cardiac motion are model-based illustrations, not acoustic ultrasound images. They are not clinically validated for diagnosis, measurements or wall-motion assessment. Use them alongside real images, textbooks and supervised training.

Verdict

The call

Vent Sim and TEE Simulator 3D are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
