Platelets are in adequate supply largely due to hospitals (in my service area) enforcing restrictive transfusion measures and postponing elective surgeries. Most blood centers except in New York, Washington state, and California are treading water with respect to RBCs. As usual Rh neg units are in short supply.
Most of the hospitals in my service area are also freeing up beds to treat respiratory infections. These will require fewer transfusions, although patients needing ECMO are of concern.
Looking ahead, it is difficult to predict what will happen. This is a long term event. My current concern is that blood donors will be fatigued 3 weeks from now and avoid giving blood. That is what happened after 9/11. It could be that you might need that unit of O neg on your shelf 42 days from now.
In my opinion the goal is to provide blood for everyone who needs blood. Measures to restrict are prudent (and the literature indicates this is good medicine). After this is all over and we are criticized for being too conservative, but no one died for lack of blood, I can live with that.
