General Overview of the Web Application

PulseVision is a web application designed to visualize synthetic Photoplethysmogram (PPG) waveforms. PPG signals are used to monitor cardiovascular parameters such as heart rate and oxygen saturation. This application allows users to interactively adjust key parameters like heart rate, oxygen saturation, waveform sharpness, noise level, and dicrotic notch intensity, which are then reflected in real-time on the waveform display. Users can explore how changes in these parameters affect the overall PPG waveform, providing an educational and insightful demonstration of cardiovascular health data.

Instructions for Using the Web Application

This application provides several sliders that allow you to manipulate the characteristics of the PPG waveform:

Heart Rate (BPM): Use this slider to adjust the heart rate in beats per minute (BPM). Increasing the heart rate makes the waveform cycles more frequent, representing faster heartbeats, while decreasing it makes them less frequent.
Oxygen Saturation (%): This slider controls the oxygen saturation level, affecting the amplitude of the waveform. Higher oxygen levels increase the height of the waveform, indicating stronger pulses, while lower levels make the waveform less pronounced.
Waveform Sharpness: Adjusting this slider changes how sharp or rounded the peaks of the waveform appear. Higher values make the waveform more pointed and distinct, while lower values make it smoother and rounder.
Noise Level: Use this slider to add noise to the waveform. Increasing the noise level simulates real-world signal imperfections, making the waveform more irregular, while reducing it makes the waveform cleaner and smoother.
Dicrotic Notch Intensity: This slider controls the intensity of the dicrotic notch, which is a secondary deflection commonly seen in PPG waveforms after the main peak. Higher values make this feature more pronounced, while lower values reduce its impact.

Future Directions

Future improvements for PulseVision could include additional controls to simulate other physiological parameters, such as respiratory rate or blood pressure. Another potential enhancement is the ability to save or export the generated waveform as an image or data file for further analysis. Additionally, incorporating pre-set conditions such as tachycardia, bradycardia, or hypoxia could help users better understand how different cardiovascular conditions affect the PPG waveform.

list the additional sliders for the dicrotic notch start and end positions as potential future enhancements. This will let us assess user feedback on the current version and add the features if users seem interested in more detailed control.

Questions for Further Development

Would you like to simulate abnormalities, like arrhythmias, by distorting the waveform dynamically? This could add an educational layer for users interested in understanding irregular heart patterns.

Are there specific health metrics you’d want to extract or calculate in real time based on waveform changes? For example, HRV could be a meaningful addition, especially for people interested in biofeedback.

Would you like to add predefined waveform presets? This would allow users to select a waveform for common conditions (like tachycardia or hypoxia) and see its impact without adjusting individual parameters.

Should users be able to save or export waveforms they create? This could be useful for educators or researchers wanting to share visuals.

Would visual elements, like color changes in the waveform based on oxygen levels, be helpful to better illustrate physiological effects?
