Summary

Normal oxygen saturation (OSAT) in children is typically above 97%. Lower OSAT values, even if not requiring immediate oxygen therapy, may indicate underlying respiratory or cardiovascular issues.

Area of Science:

  • Pediatric Medicine
  • Critical Care
  • Pulmonology

Background:

  • Pulse oximetry is a key tool for assessing oxygenation in pediatric patients.
  • Establishing normal oxygen saturation (OSAT) values is crucial for accurate clinical assessment.

Purpose of the Study:

  • To determine normal oxygen saturation (OSAT) values in infants and children using pulse oximetry.
  • To correlate OSAT levels with the presence of respiratory infection (RI) or airway, pulmonary, and cardiovascular (APC) system involvement.

Main Methods:

  • Infants and children undergoing elective surgery were assessed for OSAT in room air.
  • Patients were categorized based on the absence of RI symptoms and non-APC related surgery to define a "normal" group.

Main Results:

Related Experiment Videos

  • A significant percentage of patients with OSAT between 95%-96.5% had either RI symptoms or were undergoing APC surgery.
  • OSAT values of 97% or higher were more consistently associated with the absence of these conditions.

Conclusions:

  • OSAT values of 95% and 96% should be considered potentially abnormal due to their association with higher rates of APC/RI.
  • An OSAT of 97% is borderline normal, and values below this threshold indicate an increased risk of APC/RI conditions.
