Doctor Hu's face was expressionless, his gaze fixed on the patient with furrowed brows. It was clear that he had exhausted all efforts to save the patient, but to little avail.
The nurse was already administering respiratory nebulization to the patient.
The effect was equally poor.
Pulmonary fibrosis is an irreversible lesion, which makes breathing increasingly difficult for the patient.
A normal person's lungs are composed of many alveoli.
An adult's total alveolar surface area is about as big as a house, spread out at about one hundred square meters.
When pulmonary fibrosis occurs, the contraction and movement of the alveoli are severely affected.
It is like a rubber balloon that can easily be inflated.
But when the balloon's walls harden and lose elasticity, inflating it or letting the air out becomes difficult.
