Model-Esophageal catheter Pmus Validation epochs (n = 50)

Guillermo Gutierrez provides raw data for esophageal pressure (Pes) validation and muscle pressure (Pmus) correlation analysis. The dataset consists of 50 individual epochs, each containing 131-second-long recordings of airway pressure, flow, and esophageal pressure signals. It was last updated on April 22, 2026, and is shared under a CC-BY-4.0 license.

Use Cases

• Validate esophageal pressure (Pes) measurement techniques based on the provided airway and esophageal pressure signals.
• Correlate muscle pressure (Pmus) with pressure-time product (PTP) using the plotted data mentioned in the description.
• Perform standard linear regression (LOS Pearson's) analysis on the pressure and flow signals.
• Analyze respiratory waveforms over 131-second epochs to study breathing patterns.

Strengths

• Contains 50 distinct epochs for validation and analysis.
• Each epoch provides 131 seconds of continuous airway pressure, flow, and esophageal pressure signals.
• Data is openly shared under a permissive CC-BY-4.0 license.

Limitations

• Data is provided in a 16.3 MB PDF file, which may require extraction and preprocessing for computational analysis.
• Column-level documentation and sample data are unavailable, requiring field semantics to be inferred.
• The dataset's small scale (16.3 MB) may limit the scope of analysis.
