Hint : Use well-perfused sites for accurate SpOโ‚‚.

Correct Answers:

  • Earlobe


Rationale :

๐Ÿ’Ž The earlobe is ideal for measuring oxygen saturation when the fingers or toes are affected by edema, poor circulation, or nail thickening, as these conditions interfere with light transmission.

๐Ÿ’Ž The earlobe has good perfusion and is less affected by peripheral vasoconstriction, providing a more accurate SpOโ‚‚ reading.

๐Ÿ’Ž Other common sites like fingers or toes can give false low readings due to swelling or nail deformities.

๐Ÿ’Ž The probe should be applied securely but gently to ensure optimal sensor contact and stable waveforms.
