Canine Renal Tissue Oxygenation Data During Abdominal Compartment Syndrome

Vaia Nalbanti's experimental study provides data on renal cortical oxygenation, hemodynamics, and respiratory parameters in eight dogs under elevated intra-abdominal pressure. The dataset, last updated in 2026, includes measurements of renal partial tissue oxygen tension, urine output, arterial blood gases, and lung compliance at baseline, 15 mmHg, 30 mmHg, and after decompression. The findings demonstrate significant renal hypoxia and reduced diuresis during intra-abdominal hypertension.

Use Cases

• Modeling the relationship between intra-abdominal pressure and renal cortical hypoxia based on partial tissue oxygen tension measurements.
• Analyzing the correlation between hemodynamic stability and renal dysfunction using heart rate, mean arterial pressure, and urine output data.
• Investigating respiratory mechanics during intra-abdominal hypertension using lung compliance and arterial blood gas data.

Strengths

• Includes direct, continuous measurements of renal cortical partial tissue oxygen tension, a key metric for tissue hypoxia.
• Reports specific quantitative results, such as a 30% reduction in ptiO₂ at 15 mmHg and a 49% reduction at 30 mmHg.
• Provides a controlled experimental design with measurements across multiple phases: baseline, two pressure levels, and decompression.

Limitations

• The dataset is very small at 39.2 KB, suggesting limited scope and likely a single document rather than a large data table.
• Column-level documentation is absent; field semantics must be inferred after download from the descriptive text.
• Row count is unknown, which may limit suitability assessment for statistical modeling.
