H-SIM App – Latest Update We’re excited to bring you a powerful new update packed with new features, critical improvements, and vital bug fixes to enhance realism, usability, and training efficiency. New Features & Enhancements • Ventricular Fibrillation Rhythm updated for a more realistic ECG appearance. • Patient Details (Weight, Height, Age) now appear clearly on the HM bottom strip. • AI Mode enhancements for smoother modification of sub-scenarios, with better control over heart pump output and ECMO mode persistence. • ABG Report now shows on the IP’s MFM screen, allowing trainers to preview decisions trainees are making. • AI Animation Button added for visual feedback during AI-mode simulation. • “New Scenario” text in Sub-Scenario view corrected to “New Sub-Scenario.” • Manual Scenarios section now includes the “Add New Scenario” option, previously missing. • Added design view for ABG reports on IP mirror screens for better visibility during sessions. • New Feature: Cavitation on VA ECMO – instructors can now select No air, Mild air, Moderate air, Severe air directly from the instructor panel for realistic training. • Improved ABG formulae for more realistic laboratory results. Fixes & Stability Improvements • Lactate range locked to 0–20 mmol/L (minimum fixed at 0). • Respiratory alarm minimum value corrected to 0. • ABG window in IP view now resizes to display full image without cropping. • Removed “–” symbol from HM temperature display. • Limit removed from Third-Degree Heart Block wave, enabling more flexible simulations. • Fixed syncing issue where Heart Pump output in one sub-scenario was incorrectly applied to others. • Corrected bug where saving venous obstruction changed to arterial obstruction at 80. • Improved ABG-to-MFM-to-HM connectivity for seamless data flow. • Addressed ECMO video playback issue from U-SIM TestFlight version. • Hardware settings now fixed and stable in Custom Sub-Scenarios. • Ventricular Fibrillation no longer generates a pulse on the Heart Pump (supports non-pulsatile flow). • ABP Systolic and Diastolic values corrected in Custom Sub-Scenario charts. • Drug effects now directly linked to SpO₂ for a more realistic physiological response. • Patient respiratory system settings and details are now correctly stored and preserved between sessions. This Update Brings You: Realistic rhythms, ABG results & physiological responses Reliable sub-scenario customization in AI mode Cavitation training & non-pulsatile flow simulation Correct data storage in patient and respiratory settings Clearer visualization for trainers & smoother UI logic More accurate alarms, parameters, and waveform handling
