Yes, first responders can still utilize an OPA to help maintain and secure the airway, even when a foreign body is suspected. Before inserting an OPA, responders should first inspect the airway to determine whether the foreign body is visible. If the object is visible and can be safely removed, responders should attempt to remove it.

If an OPA is inserted when a visible foreign body is present, there is a risk of pushing the object further into the airway, potentially worsening the obstruction. Therefore, the airway should always be inspected before inserting an OPA.

It is also important to remember that blind finger sweeps should not be performed when a foreign body is suspected, as this may inadvertently push the object deeper into the airway and worsen the obstruction.
