The U.S. Food and Drug Administration (FDA) has approved a new
system for use in clearing secretions from the airways in the
lungs of potential donors, improving the quality of the lungs
for transplantation.
Advanced Respiratory
said the system, called The Link, consists of an inflatable
vest connected by hoses to an air-pulse generator. The generator
rapidly inflates and deflates the vest, oscillating the donor's
chest wall to create airflow within the lungs. This process moves
mucus from smaller airways toward the larger airways where it
can be cleared by suctioning.
In many cases, the
lungs of potential donors are not suitable for transplantation
because significant inflammation, excess secretions, contamination,
and mucus plugging damage them.
Three Organ Procurement
Organizations in California and Oregon have been testing The Link
system to assess its potential to improve the organ donor management
process and to increase the number of lungs successfully procured.
"Our initial findings
indicate that administering airway clearance therapy via The Link
system to potential lung donors greatly increases the rate of
lung procurement and improves the quality of allografts within
a controlled study group," said Sarah Riznyk of the Pacific
Northwest Transplant Bank.
"With The Link
system, we are able to resolve issues with atelectasis and pulmonary
infiltrates, which may be verified by donor chest x-rays, gram
stains and pulmonary functions," she said.
