Rewind back with me to just over three weeks ago.  I, again, should have been sleeping.  Instead I was up praying for Brian and his mama, as I had just heard that Brian had been transferred back to the ICU that morning, and I was sure I would be taking care of him again that night, if he made it that long.
   Unable to sleep, I read and prayed for a while, then made my way up to deck 8 to relax in the sunshine, enjoy the breeze, and watch the sun slowly sink into the ocean.  I had been up there a few hours and was almost asleep when we heard the announcement, "All crew with type A+ or B+ blood please report immediately to the laboratory.  If we do not find enough donors then surgeries may have to be cancelled."  I packed up my things and headed down, knowing they wouldn't let me donate again after just 3 weeks, figuring I could help draw samples or units for donation.  Less than a minute later I found myself unable to get down to the lab via normal routes; the stairs were already packed with potential donors, and nurses there to volunteer.  As I rapidly set up a makeshift phlebotomy station with tourniquet, tubes and alcohol, I heard the next overhead page.   "All nurses not currently working, please report to the laboratory immediately."  And the floodgates opened.

   Most of our patients have type A+ or B+ blood.  We have no way of separating blood parts, or even properly storing units, which means donors must be an exact match, and donate immediately before transfusion.  Since A+ and B+ are less common among Caucasians, those of us with this type blood and no debilitating illness end up donating often, though even this is not always enough.
