How Blood Banks Use Dry Ice

If you give blood regularly, you may have never thought about how the donated blood makes it from point A to point B. It is essential to keep blood cold enough so that it is fresh and usable when medical professionals need to use it. Dry ice is an essential part of protecting the vital good that comes from donated blood.

You might wonder how long dry ice lasts. There is not a solid answer to that question because it depends on the size of the piece of dry ice and the conditions under which it is being stored. Dry ice, when put in a standard ice chest, turns from a solid to a gas at the rate of about 5-10 pounds per day. When the ice chest is outside, this rate of exchange from solid to gas speeds up to 5-10 pounds every 3-5 hours. This same amount of dry ice disappears as quickly as 15-45 minutes if you put it in liquid.

Your dry ice will last longer if you keep it in a place that is as cold as possible. People who work with dry ice need to make sure that they practice safety tips such as keeping the ice well ventilated and not sealing it tightly in a container or ice chest.

Blood Specimens and Cold Temperatures

As mentioned above, keeping a proper cold temperature is the most important part of protecting blood specimens. All of these factors have an effect on the usability and quality of the samples: the temperature when the blood is collected, the temperature when it is transported, and the temperature at which the blood is stored for the long-term.  In order to form clots, serum samples must be at room temperature. The proper temperature keeps proteins and enzyme activity stable. Dry ice keeps the blood at the right temperature and maintains it properly for the most effective usability. Medical environments and blood banks use this great tool to keep the blood samples cold while handling and transporting them.

Examining the Optimal Conditions for Blood Specimen Storage

If blood specimens are to be stored long-term, you should keep the temperature around -80 degrees Celsius. Dry ice is the perfect tool for storing blood in a very cold environment. This is especially true as longs as it is monitored and properly used. You should limit the number of freeze-thaw cycles that the blood goes through during storage. This keeps the blood in a high-quality state. If you transport blood, serum, and plasma samples, make sure to pack them in plenty of dry ice for your trip so that the proper temperature is maintained. This procedure is essential whether you are moving the materials to a different floor in the same building, or you are going across town to a different medical facility. If samples thaw, they cannot be usable, so plan for potential delays.
