Nasal Flaring
Multimedia
Definition
Nasal flaring is the enlargement of the opening of the nostrils during breathing. It is often a sign that increased effort is needed to breathe.
Alternative Names
Flaring of the alae nasi (nostrils); Nostrils - flaring
Considerations
Nasal flaring is seen mostly in infants and younger children.
Any condition that causes the infant to work harder to breathe can cause nasal flaring. While many causes of nasal flaring are not serious, some can be life threatening.
In young infants, nasal flaring can be a very important symptom of respiratory distress.
Common Causes
- Asthma (acute)
- Airway obstruction (any cause)
- Bronchiolitis
- Croup
- Epiglottitis (acute)
- Pneumonia
- Transient tachypnea of the newborn

What to expect at your health care provider's office
The health care provider will perform a physical exam to determine if the flaring is due to upper or lower respiratory problems. The exam will include careful listening to the breath sounds. This is called auscultation.
Medical history questions may include:
- When did it start?
- Is the person getting better or worse?
- Does the person look blue?
- Is the breathing noisy, or are there wheezing sounds?
- Are there grunting noises with the breathing?
- Does the person look like they are working hard to breathe?
- Are they getting tired or sweaty?
- Do the muscles of the stomach, shoulders, or rib cage need to be used when the person is breathing? (See: intercostal retractions)
- What other symptoms does the person have?
The following tests may be performed:
- Arterial blood gas analysis
- Complete blood count (CBC)
- ECG
- Pulse oximetry to measure blood oxygen level
- X-rays of the chest
The patient may be given oxygen.
