When a paramedic listens to a patient's chest and hears no breath sounds, several potential conditions could be causing this symptom.
Asthma is a inflammatory disease of the airways, characterized by episodes of wheezing, breathlessness, chest tightness, and coughing. During an asthma attack, the airways narrow due to inflammation and bronchoconstriction, which can significantly reduce airflow. If we hear a slient chest in asthma it is typically bilaterally.
On the other hand, a pneumothorax occurs when air enters the pleural space, the area between the lung and the chest wall. This can cause the lung to collapse partially or completely, leading to absent breath sounds over the affected area. This is typically unilaterally is the key finding.
