Analysis of pulse oximetry data in normal sleeping children

Area of Science:

• Pediatric Sleep Medicine
• Respiratory Physiology

Background:

• Establishing normative data for physiological parameters in children is crucial for accurate clinical assessment.
• Previous research may lack comprehensive data on oxygen saturation during sleep in a home environment for healthy children.

Purpose of the Study:

• To define the normal range of oxygen saturation levels in children up to 10 years of age during sleep.
• To provide reference values for various oxygen saturation parameters to aid in the identification of abnormal pediatric sleep.

Main Methods:

• Stratified random sampling of children aged 0-10 years from a UK general practice population.
• Overnight polysomnography (pulse oximetry) conducted in the children's home environment.
• Statistical analysis of recorded oxygen saturation data to determine mean, median, mode, maximum, fifth centile, quartiles, and frequency of oxygen saturation dips.

Main Results:

• Detailed normative ranges for oxygen saturation parameters (mean, median, mode, max, 5th centile, quartiles) during sleep were established.
• The frequency of oxygen saturation dips exceeding 4% per hour was quantified for normal sleeping children.
• The study provides a comprehensive dataset for pediatric nocturnal oxygen saturation.

Conclusions:

• The established normal ranges for oxygen saturation in sleeping children provide a benchmark for clinical evaluation.
• These normative values are essential for distinguishing normal from abnormal pediatric sleep-disordered breathing.
• This research contributes valuable data for the diagnosis and management of sleep-related respiratory conditions in children.
