Overview

Retrospective analysis identifies oxygen saturation levels indicating hypoxaemia in children with chronic diseases.

Key Points

  • Oxygen saturation ≤95% indicates hypoxaemia and correlates with pulmonary function test abnormalities.
  • In a cohort of 2641 children, the prevalence of SpO 2 <98% was 4.3%, mostly in those with chronic respiratory conditions.
  • The study utilized arterial blood gas analyses and pulse oximetry recordings to define hypoxaemia thresholds.
  • Findings support the diagnosis of chronic respiratory insufficiency using repeated SpO 2 measurements and oximetry.
