Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 21 years or younger who require arterial vascular access as part of their routine clinical care.

Probably not a fit

Patients with conditions like anemia, methemoglobinemia, or those who are non-pulsatile may not benefit from this study.

What this trial studies

This observational study aims to enroll 154 children with arterial lines to assess the accuracy of pulse oximeters in those with darker skin pigmentation. It seeks to determine if pulse oximeters overestimate blood oxygen levels, a concern highlighted in adult studies but less explored in pediatric populations. By measuring skin pigmentation objectively and correlating it with pulse oximetry readings, the study aims to identify potential biases that could lead to health disparities. The research is funded by the FDA through the Stanford-UCSF Clinical Excellence in Regulatory Science and Innovation Program.

Why it matters

Potential benefit: If successful, this study could improve the accuracy of pulse oximetry in children with darker skin, leading to better clinical outcomes and reduced health disparities.

How similar studies have gone: While prior studies have indicated potential biases in pulse oximetry, this prospective approach focusing on pediatric patients with darker skin pigmentation is relatively novel.
