This therapy is subsequently a brief alternative for the perform of the lungs—and likewise for the center when utilized appropriately. This provides the physique time for its organs to get well and resume their perform or alternatively bridges the time till a lung transplant may be carried out.
ECMO therapy: helpful therapy possibility for COVID-19
Many COVID-19 affected person solely have reasonable signs.
