Evaluation of Pulse Oximetry Readings

Pulse oximetry readings in patients with acute chest syndrome may be unreliable due to potential inaccuracies. Data suggests that pulse oximetry can underestimate pulmonary infarction and overestimate arterial blood oxygen saturation. Factors like hypothermia, hypotension, and basal constriction can influence readings. In cases of inconsistency between clinical status and pulse oximetry, consider obtaining an ABG or using co-oximetry.
