Inspiratory wheeze and asthma

A wheeze is usually a musical sound created as air moves through narrowed lower airways. Asthma can present with expiratory wheeze, cough, breathlessness, and chest tightness, with symptoms that vary over time or after triggers.

A harsh, high-pitched sound that is loudest over the neck while breathing in may be stridor rather than a lower-airway wheeze. Upper-airway swelling, a foreign object, vocal-cord problems, or other causes may produce this pattern. The sound alone cannot establish its cause.

Note whether the noise occurs on breathing in, breathing out, or both, and whether it began suddenly. Record accompanying voice change, throat swelling, fever, choking, cough, chest tightness, or exposure to a known trigger. A short recording may help if the sound stops before the appointment, but never delay care to make one.

If you have diagnosed asthma, follow your written action plan and use prescribed inhalers exactly as directed. Arrange assessment when a new inspiratory sound persists, recurs, or differs from your familiar asthma symptoms; examination may need to include both the chest and upper airway.

Call emergency services for noisy breathing with severe breathlessness, rapidly worsening throat or facial swelling, inability to swallow saliva, blue or grey lips, confusion, collapse, choking, or inability to speak normally. These signs can reflect critical airway narrowing and need immediate assessment, regardless of whether asthma is already diagnosed.

Ask whether the sound is wheeze or stridor, whether it seems to arise from the chest or throat, and whether breathing tests or an upper-airway examination are appropriate. Also clarify how your asthma action plan should change if the noise returns.
