What causes diminished lung sounds in lower lobes?

Diminished or Absent Breath Sounds Intensity can be reduced due to several factors: Weak sound generation and/or impaired transmission. Various causes are shallow breathing, airway obstruction, bulla, hyperinflation, pneumothorax, pleural effusion or thickening, and obesity.

What does mild asthma sound like?

The most common symptoms of asthma are: wheezing (a whistling sound when breathing) breathlessness. a tight chest – it may feel like a band is tightening around it.

Does asthma cause stridor?

Stridor: Causes and possible diseases in adults In adults, expiratory stridor is more common. The causes of stridor often are associated with the bronchi and the lungs.
