Abstract in brief

  • Pulse oximetry is a noninvasive and continuous method that has significantly improved the monitoring of blood oxygen levels, yet many healthcare providers are unaware of its underlying principles.
  • Understanding how pulse oximeters differentiate between oxygenated and deoxygenated hemoglobin, and that they only measure arterial blood, is essential for identifying when readings might be inaccurate.
  • The article explains the mechanisms of pulse oximetry and discusses conditions that can lead to false readings, emphasizing the importance of knowing these limitations in clinical practice.
