Snuffbox Artery Ultrasound Measurements from a Prospective ICU Study, 2024

A dataset of snuffbox artery ultrasound parameters and vital signs from a single-center prospective observational study. It includes measurements from 91 healthy volunteers and 55 intensive care unit patients collected between February and November 2024. The study established normal reference ranges for the resistance and pulsatility indices in healthy adults.

Use Cases

• Establishing baseline reference ranges for snuffbox artery ultrasound parameters based on the reported resistance and pulsatility indices.
• Comparing hemodynamic parameters between healthy populations and ICU patients based on the study's cohort design.
• Investigating the prognostic value of end-diastolic flow velocity for patient outcomes based on its reported association with 28-day mortality.
• Evaluating the utility of ultrasound-derived indices as surrogates for systemic vascular resistance based on the described physiological limitations.

Strengths

• Includes data from 146 total participants (91 healthy volunteers and 55 ICU patients).
• Provides specific normal reference ranges for key indices: resistance index (0.72–0.75) and pulsatility index (1.93–2.03).
• Data collection was standardized, with measurements taken under controlled conditions.
• Dataset is openly licensed under CC-BY-4.0.

Limitations

• Row count and column-level documentation are unknown, which limits suitability assessment.
• Data is from a single-center study at one hospital in China, which may limit generalizability.
• The dataset is very small (20.9 KB), indicating limited scope.
