What is the Lung Allocation Score System?

According to the lung condition of the patient, a score is given. This score helps in identifying the patients with severe lung disease, patients who need double lung transplantation, single lung transplantation, or can withstand a few months with their lungs. According to the score, the patients are allotted their donors. Patients with end-stage lung failure (both the lungs have stopped functioning properly) are given priority.
