Performance of Pulse Oximeter Sensors in Neonates

Researchers at the University of California, San Francisco have developed methods that permit
them to test multiple pulse oximeter sensors on neonates simultaneously during cardiac
surgery. During this type of surgery, the arterial oxygen saturation changes over a wide
range, providing an ideal arena for the assessment of neonatal pulse oximeter sensors at many
levels of oxygen saturation. Several arterial blood gas samples are typically obtained during
these procedures. Saturation of each arterial blood sample is determined by direct oximetry
in a hemoximeter and this measurement is compared to the reading displayed on the pulse
oximeter.

Inclusion Criteria:

- Neonates scheduled to undergo cardiac surgery where routine blood draws would be taken

- Consent signed by at least one legal guardian

Exclusion Criteria:

- Presence of any skin irritation or breakdown on the foot

- Foot impediments which would preclude proper placement of the sensor

- Clinical condition precluding the use of adhesive materials
