    Introduction Peripheral pulse oximeters with continuous monitoring of heart rate and saturation have revolutionized neonatal care. Motion artifacts, hypothermia, and poor perfusion are some of the barriers for reliable reading in the transmittance type of peripheral pulse oximeters. This study was planned to assess the effectiveness of transmittance sensors applied over the forehead for monitoring the heart rate and saturation. Material and Methods An observation study was conducted over a period of 1 month. Two pulse oximeters (Masimo RAD97) were applied simultaneously, one over the periphery (right hand/wrist) and the other over the forehead using an innovative headband. A total of 540 readings of heart rate and saturation (SpO2) from each site were recorded. A difference of more than 5 beats/minute in heart rate and 2% saturation were considered clinically significant. Results Forty-five neonates with mean gestational age of 35.3 ± 3.2 weeks and birth weight of 2109 ± 683 grams were enrolled. Forehead pulse oximeter could pick up the heart rate and SpO2 readings in all the babies. A statistically significant difference of 3.8 beats/minute in heart rate and 2.5% in SpO2 was noted (p-value < 0.0001). The difference in heart rate was not clinically significant. Conclusion We propose that the transmittance type peripheral pulse oximeter sensors can be used over the forehead. It has the potential to avoid erroneous readings due to motion artifacts, hypothermia, or shock. Saturation nomograms for the forehead pulse oximetry need to be established before it can be used to monitor and manage the neonates for the same.
