Medela's Thopaz+ takes chest drainage therapy to a new level of care. Unlike analogue systems, it reliably regulates the applied pressure at the patient's chest and digitally (and quietly) monitors critical therapy indicators. Clinical data has demonstrated that Medela's chest drainage therapy improves outcomes and streamlines the delivery of care. This simulator helps you to become familiar with Thopaz+ and its advanced functions. You can… - simulate a functional check - simulate visual and audio warnings and alarms - simulate the catheter check - change all menu settings - simulate fluid drainage - see examples of air leak and fluid histories - see an example of an event history DISCLAIMER:  This app is intended to be a tool to provide information only. This app is not intended to be a source of medical advice or treatment and does not replace in any way your independent medical advice regarding your patient’s diagnosis or treatment. The app does not interact Thopaz+ in any way and cannot impact, change, alter or amend any treatment you prescribe or program.  Only you can determine whether the Thopaz+ is right for your patient. Before initiating Thopaz+ treatment in any patient, read the instructions for use, indications, contraindications, warnings, precautions and safety instructions. Nothing in this app should be construed as replacing, revising or amending the information contained in the instructions for use, contraindications, warnings, precautions and safety instructions.

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) plus 1 scene you fix by changing ventilator settings (hypoxemia in ARDS), 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.

Verdict

The call

The clearest difference is in-app purchases: Thopaz+ Simulator at none against Vent Sim's 1. Thopaz+ Simulator also leads on iOS requirement (12.0 vs 15.4). Vent Sim's advantage is update cadence (weekly vs every 85 months). On price, ads and device support there is nothing between them.
