(HealthDay News) — It’s only natural that parents of children with asthma worry about the condition flaring up.

But which symptoms actually warrant a trip to the emergency room? The Nemours Foundation says to keep your eyes peeled for these warning signs:

• Your child’s nails or face color turns blue or grayish.
• Your child has trouble talking.
• You can see the area between your child’s ribs or base of the neck contract.
• Your child’s rescue medications aren’t working to stop the flare-up.

If your child shows any of these signs, seek medical attention immediately.
