Cardiorespiratory data from Atlantic salmon exposed to progressive hypoxia after acute warming from 10 to 14 and 18°C. The dataset includes heart rate, stroke volume, cardiac output, oxygen consumption, blood oxygen extraction, and thresholds like critical oxygen tension. The data was collected by Fiona Paula Helena Durnford and was last updated on May 9, 2026.
Use Cases
- Modeling hypoxia tolerance thresholds based on critical oxygen tension (Pcrit) data
- Analyzing the impact of thermal history on cardiac performance based on heart rate and cardiac output
- Studying physiological failure points using the oxygen levels for bradycardia initiation (IOB) and loss of equilibrium (LOE)
Strengths
- Includes multiple cardiorespiratory variables such as heart rate, stroke volume, and cardiac output
- Captures physiological thresholds like Pcrit, IOB, and LOE under controlled experimental conditions
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
