Tests and diagnosis
By Mayo Clinic staffIf the medical team suspects epiglottitis, the first priority is to ensure that your or your child's airway is open and that enough oxygen is getting through. Oxygen levels are monitored using a device called a pulse oximeter. This device, similar to a clothespin, clips on to a finger and measures the amount of oxygen saturation in your blood. If levels drop too low, you or your child will need help breathing.
Once your or your child's condition is stable, the doctor may:
- Examine the throat. Using a flexible fiber-optic tube, the doctor may look down your or your child's throat to see what's causing the symptoms. A local anesthetic can help relieve any discomfort.
- Request a chest or neck X-ray. Because of the danger of sudden breathing problems, children may have X-rays taken at their bedside rather than in the radiology department — but only after the airway is protected.
- Perform a throat culture and blood tests. For the culture, the epiglottis is wiped with a cotton swab and the tissue sample is checked for Hib. Blood cultures are usually taken because bacteremia — a severe bloodstream infection — may accompany epiglottitis.
