PulseArk is intended for general wellness, health education, and lifestyle guidance only. The information provided in this application does not constitute medical advice, diagnosis, or treatment. Users should consult qualified healthcare professionals for medical concerns or health-related decisions.

Measure Module

The Measure module allows users to record and monitor general health indicators such as heart rate, HRV, blood pressure reference ranges, blood oxygen reference ranges, weight, and BMI. These indicators are used to generate general wellness insights related to Stress, Tension, and Energy trends.

Photoplethysmography (PPG)

The PulseArk application includes a heart rate measurement feature that uses the smartphone camera and flash. This technique relies on photoplethysmography (PPG), a non-invasive optical method widely used in wearable devices and consumer health applications.

These studies demonstrate that smartphone-based PPG methods can be used for general heart rate estimation in consumer health applications.

Heart Rate Variability (HRV)

HRV is commonly used as a physiological indicator related to stress and autonomic nervous system balance.

Summary

Test Module

The Test Module provides a series of well-established psychological and health self-assessment questionnaires designed to help users better understand their emotional state, stress levels, sleep quality, and general cardiovascular awareness. These questionnaires are not diagnostic tools. They are intended solely for self-reflection, educational awareness, and general wellness guidance. The design of the Test Module references internationally recognized health guidelines, epidemiological research, and validated psychological assessment scales.

1. International Health Guidelines

The health education information used within the Test Module references publicly available guidance and research from major global health organizations, including:

These references provide general background information for health education within the application.

2. Cardiovascular Health Risk Awareness Models

Some educational explanations within the Test Module reference commonly used cardiovascular risk awareness models that are widely cited in epidemiological research:

These models are referenced for educational context only and are not used for clinical diagnosis within the application.

3. Research on Heart Rate Awareness

Educational content related to heart rate awareness and common cardiovascular symptoms references materials from:

These materials provide general background knowledge about cardiovascular health.

4. Blood Pressure and Cardiovascular Risk Research

General health knowledge within the Test Module references research and guidelines related to hypertension and cardiovascular risk factors:

These references support general health education within the application.

5. Self-Assessment Questionnaires Used in the App

The Test Module includes several widely used psychological and health self-assessment questionnaires. These tools have been published in peer-reviewed research and are commonly used in academic or wellness screening contexts.

6. AI-Assisted Recommendation Support

Some general wellness suggestions presented after self-assessments are generated with assistance from a large language model provided by OpenAI.
