The American Red Cross is facing a national blood crisis – its worst blood shortage in more than a decade. The Red Cross says dangerously low blood supply levels are posing a concerning risk to patient care and forcing doctors to make difficult decisions about who receives blood transfusions and who will need to wait until more products become available. Blood and platelet donations are critically needed to help prevent further delays in vital medical treatments, and donors of all blood types – especially type O are urged to make an appointment to give now to give in the weeks ahead. In recent weeks, the Red Cross had less than a one-day supply of critical blood types and has had to limit blood product distributions to hospitals. At times, as much as one-quarter of hospital blood needs are not being met.
