Croup Diagnosis: Symptoms and What to Expect

Diagnosis is primarily clinical, based on history and physical exam. The doctor assesses cough quality (barking), stridor, hoarseness, and respiratory distress signs (rapid breathing, retractions, nasal flaring). Auscultation may reveal wheezing or crackles.

Additional Tests (if needed)

• Neck/chest X-ray: Shows airway narrowing (steeple sign).
• Laryngoscopy: Visualizes vocal cords and airway.
• Pulse oximetry: Measures blood oxygen saturation.

Combined findings confirm croup and guide treatment.
