Project nGene.org® v1.5 expands ICA with heart/lung sound source libraries and improves educational waveform add-on workflows.

Project nGene.org® is a research-oriented medical software workbench designed by Hyunsuk Frank Roh, MD, for hemodynamic modeling, waveform analysis, anatomy visualization, and educational medical computation.

For technical compatibility within iOS systems, the app name appears as "Project_nGene.org" while representing Project nGene.org®.

The app currently includes: • Hemodynamic model exploration • Logistic-Based Systolic Model simulation • Medical equation tools • Independent Component Analysis waveform demonstration • Chest vascularity visualization • MDRO research dataset viewer • Optional Virtual Ventilator Test-Lung educational add-on • Optional Virtual EKG Simulator educational add-on • Optional Echocardiography Recognition educational preview • Optional IV Nutrition Therapy formulation helper

Version 1.5 expands the Independent Component Analysis module with additional educational heart and lung sound source libraries. The ICA workflow now supports selection of one heart sound source and one lung sound source, mixing them into observed channels, and applying ICA to estimate separated components.

The added heart sound pool is based on the UMich Heart Sound & Murmur Library from Open Michigan / University of Michigan and is used under Creative Commons Attribution 4.0 terms, except where otherwise noted by the source. The added lung sound pool is based on HLS-CMDS: Heart and Lung Sounds Dataset Recorded from a Clinical Manikin using Digital Stethoscope, Version 3, DOI: 10.17632/8972jxbpmp.3, licensed under CC BY 4.0.

Version 1.5 also refines the optional add-on workflow for iPad-focused modules. Virtual Ventilator Test-Lung and Virtual EKG Simulator remain optimized for iPad landscape use, with clearer unsupported-device guidance and Settings navigation behavior.

Version 1.4 introduced Virtual EKG Simulator, an optional educational add-on for exploring simplified ECG waveform generation. The module supports rhythm selection, heart-rate adjustment, signal-quality controls, 3-lead and expanded lead display modes, a 3D electrical vector view, a heart and electrode map, and live waveform sweep visualization.

Version 1.3 expanded the Virtual Ventilator Test-Lung add-on with a broader educational ventilator-mode workspace supporting Pressure Support, SIMV, PRVC, Pressure Control, and Volume Control. The Test-Lung module also includes Quick Ventilator Setting, RSBI, Static/Dynamic Compliance, and Ti/T-pause calculators for educational model exploration.

Version 1.1 added an educational echocardiography recognition add-on for learning echocardiography view orientation and anatomy scaffolding. The module can use the device camera to support PSAX/PLAX-style view classification and AV/PV object scaffolding for educational exploration.

The software is intended for research-oriented education, model inspection, anatomy-learning, waveform visualization, auscultation signal-processing education, and structured medical reasoning education. It is not presented as a diagnostic or treatment device, does not provide patient-specific clinical decisions, and should not be used as a substitute for clinician judgment, ventilator management, respiratory therapy protocols, ventilator-weaning decisions, ECG interpretation, cardiac rhythm diagnosis, auscultation diagnosis, or formal echocardiography interpretation.

Project nGene.org® reflects an effort to make complex hemodynamic, waveform, anatomy, respiratory, cardiac electrical, and cardiopulmonary acoustic models more visible, interactive, and understandable.
