Answer: B. Mediastinal Emphysema and Pneumothorax
Explanation:
Mediastinal emphysema is a medical condition in which air surrounds the heart and blood vessels in the mediastinum. These air are usually as a result of traumatic lung injuries or other lung pathologies which permits the alveoli which are the air sacs to release their. These air released will definitely seek a place to go and will thereafter find space around mediastinum thereby preventing adequate heart contraction and disruption in blood flow.
Pneumothorax only the other hand is a condition whereby there is air linkage between the lung and chest wall.
This two conditions occurring concurrently can lead to clinical features such as chest pain, shallow breathing, cyanosis, respiratory failure and even unconsciousness.
