A 30-year-old man has sustained an injury to his thorax in a traffic incident, which caused disruption of his external respiration. What type of ventilatory difficulty can be observed in the given case?

Answer options

1. Cardiovascular collapse
2. Impaired ventilation regulation dysfunction
3. Restrictive extrapulmonary ventilatory impairment
4. Restrictive pulmonary ventilatory impairment
5. Obstructive ventilatory impairment

Explanation

It is restrictive extra pulmonary ventilator impairment because it concerns external respiration (exhalation) and it doesn’t affect the lungs (extrapulmonary).
