Background: Pulse oximetry is widely used in the neonatal intensive care setting, with a variety of sensor choices available today. Historically, our institution has used the Nellcor brand of sensor (N25), which as performed reliably. We recently evaluated the SensAID (RC-NCR 10 -3) Sensidyne, Inc., Clearwater, Fl)) neonatal/infant pulse oximeter adhesive sensor to determine if the sensor could be substituted for the Nellcor sensor in neonates with unrepaired, cardiac defects.
Method: 16 newborns ranging from 2.7 to 4.0 kg admitted to our Cardiac ICU were selected for enrollment. After placement of an N25, a SensAID pulse oximeter sensor was attached to the same limb as the Nellcor sensor. Both sensors were simultaneously connected to a Nellcor pulse oximeter. Observed readings from both pulse oximeters at various time points were recorded and compared. Various lot numbers were used from Sensidyne, Inc.
Results: 134 paired data points were obtained. Range of displayed oxygen saturation values obtained was 11 to 97%. The r value was 0.57, Bias was 10.48, and precision was 15.21 (see chart). We observed wide variability in pulse oximeter saturation readings with the SensAID sensor, despite observing matching heart rates on both oximeters. The sensor was bulky, making it difficult to place on our patients.
Conclusions: Based on the results of our experience, we elected not to replace the Nellcor N25 sensor with the SensAID sensor.
