Blood refrigeration

Blood, plasma, and other blood components utilized in clinical and research environments are required to be stored and transported at certainspecific temperatures. This is necessary as the different components of blood - suchblood—such as red blood cells, white blood cells, platelets, and nutrients - interactnutrients—interact with each other through chemical reactions whichthat are often reliant on temepraturetemperature to function. The body's ambient temperature is around 37 degrees Celsius, where reactions normally happen normally, while higher temperatures cause molecules to break down, and cooler temperatures slow down and stop interactions. Being able to slow the interactions is important once samples or donations are obtained, asso blood can be stored without the risk of spoiling the blood.

Further, the other components of blood, such as the blood plasma and platelets, once removed through centrifugation, have other storage conditions in order to preserve the importantessential cells, proteins, and molecules for testing, research, orand clinical procedures.

Just as with different foods, vaccines, orand other protective products, there are various storage conditions for blood as well. Blood storage conditions are generally applied and include a cold chain for the preservation of blood products in transportation. Red blood cells require a blood bank refrigerator and should be stored in cabinets between 2 and 6 degrees Celsius. Meanwhile, blood bags have specific shelf lives, depending in partpartially on the temperature of the room, with thea shelf life of 42 days for a blood bag in a blood refrigerator lasting 42 days.

For plasma, whichPlasma has to be frozen quickly after donating, to a minimum of negative 40 degreedegrees Celsius. This stops the plasma from coagulating, which decreases the amount of blood. The shelf life for frozen plasma, if correctly maintained, is about one year. And theBefore plasma is used, it has to be brought to an approved temperature before it is infused. Keeping blood and related bloodblood-related products within the necessary temperature range requires various storage equipment, such as ultra-deep freezers, blood cabinets, freezer cabinets, and outdoor coolers, with systems capable of tempearturetemperature control. This can stop potentially fatal conditions whichfrom occuroccurring when storage conditions are not met and blood is contaminated, such as potentially fatal bleeding.

Blood refrigerators are used to store and protect refrigerated whole blood, blood components, and blood products. ThisThese refrigerators must maintain a uniform temperature and utilize rapid recovery systems that equalize the temperature set point when the door is done by maintaining a uniform temperature, a rapid recovery of setpoint temperature,opened and closed. Blood refrigerators are often made available in various models and sizes. Theyand can include lockable doors, chart recorders, and alarms to warn of power loss orand temperature deviations. Refrigerators for blood storage must meet the requirements of the AABB, the American National Red Cross, and the U.S. Food and Drug Administration, among others. These requirements include the following:

• Battery back-upbackup system

Further, asAs fridges become more competitive amongstamong manufacturers, andas users have more requirements for their fridges, orand as more requirements are made from local and international regulations, refrigerators have included more specialized features. These include the fridges have included more and specialized features to better meet user needs. These includefollowing:

• High qualityHigh-quality cabinet construction, including heavy walled and CFC-free installation to minimize energy use and ensure temperature stability
• Time and temperature sensitivetemperature-sensitive auto-defrost cycles with automatic condensation removelremoval to minimize equipment downtime

Part of the refrigeration and storage of blood and blood products is the cold chain, which is sometimes referred to as the blood cold chain in the transportation of blood. This cold chain tends to be a massive undertaking on a global scale, which worksworking to give access to a secure blood supply for effective healthcare around the world. This is especially important as, accordingAccording to the World Health Organization, more blood is donated in high-income countries, whichand this approximately answers for the needs for blood there, which meanswhile populous, low-income countries are consistently undersupplied in blood.

The cold chain is compromisedcomposed of various pieces of equipment whichthat allow for the systematic processes necessary for the safe storage and transportation of blood and blood components. This cold chain works to keep blood and blood components at the correct temperatures at all timetimes, from blood collection to administration. The cold chain is composed of the refrigerators, plasma freezers, platelet agitators and incubators, and blood transport boxes. The proper containment and transport of blood can reduce the blood that is lost or needs to be disposed of at the end of a day. For example, in an ambulance whichthat carries blood for emergency situations, the proper storage on the ambulance can extend the life of blood products.

The lack of donated blood is not the only problem facing many low-income countries. The equipment necessary to maintain appropriate temperatures through the cold chain can be expensive, and in some low-income countries, the expense of the refrigeration on-site, let alone for transportation, may prove prohibitively expensivecostly. While, oftenOften, these countries also expericenexperience challenging environments where temperature conditions can change drastically. And many of these countries cannot afford to produce, let alone store, blood derivatives.

Proper equipment is vital at all levels of the cold chain, regardless of the income of the country either where a donation or transfusion occurs, and can increase the effectiveness of blood transfusions across the world. The WHO is working to enable this by helping countries better monitor the cold chain, acquire the necessary equipment, and increase transparency and visibility in their cold chains.

• Doors can be locked to control access
• Directed and monitored forced-air circulation for temperature stability and for quick temperature recovery post-door opening
• At least two temperature sensors or probes at various points to provide complete cabinet temperature data for compliance with blood storage standings, as well as built-in or freestanding chart recorders for logging and monitoring temperature data
• Visual and audible alarms and alerts for the tracking of events such as temperature deviations and power failures, with battery backups to ensure alarm functionality in the event of a power failure
