What oxygen saturation threshold is used in the pediatric bronchospasm criteria for epi dosing?

• A. Less than 91% despite supplemental oxygen
• B. Less than 95%
• C. Greater than 90%
• D. Not used

Answer: (A)

The key idea is that there is a specific oxygen saturation level used to trigger epi dosing in pediatric bronchospasm: when SpO2 is below 91% despite providing supplemental oxygen. This threshold points to more pronounced hypoxemia even with oxygen support, indicating more severe bronchospasm where epinephrine may be beneficial to help open the airways. Lower thresholds like less than 95% would miss some cases of concerning hypoxemia, and a threshold greater than 90% wouldn’t reliably identify those with significant airway compromise. The option stating that no saturation criterion is used isn’t correct because this protocol does include an SpO2 threshold for dosing decisions.
