Pulse oximetry vs non-invasive blood pressure/oscillometry to record blood pressure in neonates: A prospective
1Department of Paediatrics, Malankara Orthodox Syrian Church (MOSC) Medical College Hospital, Kolenchery, Kochi, Kerala, India.
Aim:
To assess the usefulness and efficacy of pulse oximetry (disappearance/reappearance of plethsmographic waves) as a method of non-invasive blood pressure monitoring in neonates.
Objective:
To investigate the reliability of the plethysmographic wave form of the pulse oximeter to measure the systolic blood pressure.
Study Setting:
A prospective observational study was done to assess usefulness and efficacy of pulse oximetry (disappearance/reappearance of plethysmographic waves) as a method of non-invasive blood pressure monitoring in neonates.
Material And Methods:
The study was conducted among 500 neonates to investigate the reliability of the plethysmographic waveform of the pulse oximeter to measure the systolic blood pressure as it is a easy way to perform and non invasive.
Statistical Analysis Used:
The results will compare and analyse statistically by Pearson correlation co-efficient. Regression modeling will carried out to explain the relationship of non-invasive blood pressure with mean DP and RP and attempted to predict the non-invasive blood pressure from mean DP/mean RP.
Results:
The study results revealed that NIBP systolic and diastolic both correlated with DP and RP of pulse oximetry plethysmograph.
Conclusion:
Study concluded that pulse oximetry is a reliable tool in measuring blood pressure in neonates (appearance and disappearance of plethysmogram).

This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
