Blood Bank Refrigerator Temperature Dashboard

The default band is 2–6 °C, the storage range for whole blood and red cell concentrates. Treat it as a sensible starting point — your own specification, regulator, equipment manual or product datasheet sets the authoritative limits, and you can read your true band straight off the worst case those documents allow. Edit the readings against whatever band applies to you.

Red cell viability and bacterial safety drive the tighter ceiling: above 6 °C the risk of bacterial proliferation in a unit rises and post-transfusion red-cell survival falls, so transfusion standards (AABB, ISBT, national blood services) mandate 2–6 °C with continuous monitoring and alarms. The 30-minute rule for issued units is a separate, stricter control. This is why blood refrigerators are purpose-built with rapid air recovery and validated mapping, not repurposed pharmacy fridges.

Match the interval to the consequence and the rate of change: where an excursion spoils product or risks safety, log continuously (or as often as you can sample); where it is merely informative, daily or per-shift spot checks suffice. The in-range % and excursion count only mean something if your sampling is regular — sparse, irregular readings hide the excursions between them.

Yes — every reading is stored in this browser's localStorage on your device and nothing is uploaded to any server, which also makes the dashboard usable on sites with strict data policies. For shared, audit-grade records across a team or for regulatory retention, export the values into your own system.
