The above mentioned specific action would artificially induce the intrapulmonary pressure to drop below atmospheric pressure thus resulting in inspiration
Explanation:
The process of ventilation through negative pressure by the mechanical iron lung in respiration, provides a person with the ability to breathe if that person has the disability to breathe due to some disease.
We normally breathe by this pressure, in which the contraction of diaphragm and expansion of chest makes the pulmonary pressure to drop and enabling the air to flow inside it from atmosphere. This inward flowing of air is regarded as ‘inspiration’.
