Six Minute Walk Testing (6MWT) Capabilities

• Detailed Metrics: Tracks SpO2, pulse rate, and distance walked during 6MWT, with automated calculation of baseline, minimum, and maximum SpO2, peak pulse rate, and recovery time post-test.
• Customizable Reports: Generates 6MWT-specific reports with graphical and tabular data, including desaturation events (e.g., SpO2 < 88% for >5 seconds), total distance (meters), and time to recovery (SpO2 ≥ baseline).
• Event Detection: Automatically identifies and flags exercise-induced desaturation events with user-defined thresholds, supporting assessment of exertional hypoxia in conditions like COPD or pulmonary hypertension.
• Data Resolution: Records data at 1-second intervals for high-resolution analysis, capturing transient desaturations and pulse rate fluctuations during the test.
• Comparative Analysis: Allows comparison of multiple 6MWT sessions for the same patient, displaying trends in exercise capacity and oxygen saturation over time.
• Integration with Rehabilitation Protocols: Provides data export for integration with cardiopulmonary rehab software, enabling clinicians to tailor exercise prescriptions based on 6MWT performance.

Sleep Study Capabilities

• Nocturnal Monitoring: Supports overnight data collection for up to 72 hours, capturing SpO2, pulse rate, EtCO2, and respiration rate to diagnose sleep apnea, hypopnea, and other respiratory disorders.
• Event Detection and Analysis: Automatically identifies apnea (cessation of breathing >10 seconds), hypopnea (SpO2 drop ≥3% with reduced airflow), and desaturation events (e.g., SpO2 < 90%) with customizable thresholds for severity classification.
• Sleep-Specific Reports: Generates detailed Sleep Study Reports with oxygen desaturation index (ODI), apnea-hypopnea index (AHI) estimates, and time spent below SpO2 thresholds (e.g., <88%), presented in graphical and tabular formats.
• High-Resolution Data: Records data at 1-second intervals for precise tracking of transient events, with adjustable sampling rates (1, 2, or 4 seconds) to balance resolution and storage needs.
• Patient Database Management: Organizes sleep study data by patient ID, date, or study duration, enabling longitudinal analysis of sleep patterns across multiple nights.
• Integration with Polysomnography: Exports data in ASCII format for compatibility with polysomnography systems, facilitating comprehensive sleep lab workflows.
