Wheezing Presenting in - ANS-Airway disease, thickness of airway increases
Rhonchi - ANS-• Low-pitched, coarse, loud, low snoring or moaning tone; sounds like

the visceral and parietal pleurae
• Manifestations depend on the amount of fluid accumulation and the position of the

• Signs may be fever, tachypnea, dyspnea, tachycardia, decreased fremitus, trachea
shifted to the other side, and absent breath sounds on the affected side
• Symptoms may include sharp chest pain that is worse with cough or deep breaths
