Checking whether skin color affects pulse oximeter accuracy in children

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for children of all skin colors who are having a cardiac catheterization. It checks how accurate pulse oximeters are across skin colors.

Age

From 1 month to 18 years old.

Sex

All sexes can join.

Disease stage

Children undergoing a cardiac catheterization procedure that usually includes a direct arterial oxygen saturation measurement by co-oximeter.

Earlier treatment

Must not have received an intravenous vasoconstrictor before the procedure.

Main reasons for not taking part

• Took part in this study before
• Has differential cyanosis across extremities
• Received an intravenous vasoconstrictor before the procedure
• Has a ventricular assist device (VAD)

The registry criteria, word for word

What the trial wants to find out

This multisite study seeks to understand whether and how pulse oximeter accuracy varies across children with different skin colors in real world clinical settings. Many factors can affect how well pulse oximeters work; for example, movement and even fingernail polish. Some studies in adults show that skin color may also affect the pulse oximeter reading. In this study, we will explore pulse oximeter accuracy in children of all skin colors who are undergoing cardiac catheterizations. The study will address limitations of prior work by objectively measuring skin color across multiple dimensions of color and comparing the the pulse oximeter reading to the "gold standard" blood sample measurement.
