Wheeze - Monophonic

Monophonic wheezes are loud, continuous sounds occurring in inspiration, expiration or throughout the respiratory cycle. The constant pitch of these sounds creates a musical tone. The tone is lower in pitch compared to other adventitious breath sounds. The single tone suggests the narrowing of a larger airway. These lung sounds are heard over anterior, posterior and lateral chest walls. These sounds can be more intense over lung areas affected by partial obstructions.
