Can Telemedicine Treat Croup? - Pediatric Triage Guidance

Audience: pediatric

Croup is a common childhood illness that causes a distinctive barking cough and sometimes noisy breathing. It is usually caused by a viral infection affecting the upper airways. Telemedicine can help assess many mild to moderate cases of croup by reviewing symptoms and advising on care at home. However, it cannot replace urgent in-person care when a child shows signs of breathing difficulty or severe illness. Parents and caregivers can use telemedicine to get advice on managing symptoms, when to seek emergency care, and how to monitor the child’s condition. This guidance explains what telemedicine can and cannot do for croup, red flags to watch for, and how to prepare for a tele-visit. Remember, telemedicine is a helpful tool but is not a substitute for hands-on medical evaluation when a child’s breathing is at risk.

Red flags — go in person / ER

• Difficulty breathing or rapid breathing
• Stridor (noisy breathing) when calm
• Blue or gray color on lips or face

What telemedicine can do

• Assessing mild to moderate croup symptoms
• Providing home care advice
• Determining need for in-person evaluation
• Answering questions about symptom management

What telemedicine cannot do

• Performing physical examination or oxygen measurement
• Treating severe breathing difficulty
• Emergency airway management
• Administering medications requiring in-person care

What is Croup?

Croup is an infection that causes swelling around the voice box (larynx) and windpipe (trachea). It often leads to a harsh, barking cough, hoarseness, and noisy breathing called stridor. It mostly affects young children between 6 months and 3 years old. Symptoms usually start like a common cold and then progress over a few days.

How Telemedicine Can Help

Through a video or phone visit, a healthcare provider can ask about your child's symptoms, watch their breathing, and guide you on home care. They can help decide if your child can be safely cared for at home or needs to see a doctor in person. Telemedicine can provide advice on using humidified air, fever control, and when to seek emergency help.

When Telemedicine Is Not Enough

If your child has severe breathing problems, is very sleepy, or has blue lips or face, telemedicine alone is not enough. These signs require immediate in-person medical evaluation. Telemedicine cannot perform physical exams, oxygen measurements, or emergency treatments needed in serious cases.
