Pulse oximetry vs non-invasive blood pressure/oscillometry to record blood pressure in neonates: A prospective observational study.

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.
