Ordinarily there should be no sound produced during respiration. This can be tested separately for a detailed evaluation. Also, sounds may be noted during other portions of the examination. For example, at the end of maximum phonation time testing the individual will usually take a deep inspiration.
I make note of any inappropriate sound produced during:
- quiet respiration and
- deep respiration,
- forced respiration.
I note when it occurs - during:
- expiration or
- both inspiration & expiration.
I note the quality:
- white noise,
- low pitched.
