When assessing equipment readiness, which oropharyngeal airway sizes should be confirmed for infants?

To determine the appropriate size of oropharyngeal airways for infants, option zero is indeed the correct choice. Oropharyngeal airways (OPA) are designed to maintain an open airway by positioning the tongue forward and preventing it from occluding the throat.

For infants, the sizes of OPAs are designated numerically, typically starting with zero. Size zero is specifically tailored for neonatal and infant patients, accounting for their smaller oral and pharyngeal anatomy. Using an airway that is appropriately sized is critical, as a too-large or too-small OPA can lead to ineffective airway management or complications.

The other sizes, while applicable for older children and adults, do not align with the anatomical requirements for infants. As such, confirming size zero as appropriate ensures the readiness of the equipment and the safety of pediatric patients in emergency situations.
