Age and seasons influence on at-home pulse oximetry results in children evaluated for suspected obstructive sleep apnea

Italian Journal of Pediatrics, 2017
Background Seasonal variability on obstructive sleep apnea has already been studied by polysomnography in children. Winter and spring season emerged as critical periods. No data are currently available for pulse oximetry performed at home. The aim of our

Non-Invasive Capnography Versus Pulse Oximetry for Early Detection of Respiratory Depression During Pediatric Procedural Sedation: A Prospective Observational Study

Children
Background/Objectives: Continuous ventilation monitoring during pediatric sedation is essential, as respiratory depression may occur silently and may not be detected promptly by conventional methods such as pulse oximetry.

The value of peripheral perfusion index measurements for early detection of critical cardiac defects

Pediatrics and Neonatology, 2019
Background: Approximately 25% of congenital heart diseases (CHD) are estimated to be critical and require an intervention. In this study, we aimed to investigate the additional value of peripheral perfusion index (PPI) measurements to pulse oximetry ...

Accuracy and Bias of Pulse Oximetry in the Intensive Care Unit: A Prospective Observational Study. [PDF]

Nurs Crit Care
ABSTRACT Background Non‐invasive oximetry is crucial for the easy and continuous monitoring of blood oxygenation, from routine assessments to critical care in intensive care units (ICU). Studies indicate that pulse oximeter readings may be biased due to the high light absorption of melanin.

Utility of pulse-oximetry screening in newborns with nonductus-dependent cyanotic congenital heart defects: A reason to alarm?

Annals of Pediatric Cardiology, 2022
Objectives : We aimed to compare the performance of pulse-oximetry screening in detecting nonductus-dependent cyanotic congenital heart defects (CCHDs). Methods : In a prospective cross-sectional study, we recorded post ductal saturation of neonates (
