What You Should Know About Reusable Blood Warmer

By Margaret Snyder


Generally, when you donate blood and is not transfused to a patient at that time, it has to be stored in a refrigerator so as to enhance its life. Obvious, the temperature in a refrigerator is far much below the normal body blood temperature. It happens that this ice-cold fluid is transfused into the body system, conditions like hyperthermia, arrhythmias, and shock are likely to occur. That is why reusable blood warmer are used so as to provide the fluid with the necessary and appropriate temperature before being incorporated into the body.

These devices come in three different types in regard to the warming technique and technology used. The first type is the one that uses dry heat method. The other types include using a water bath and the other countercurrent. This can be done before transfusion or during the process which is referred to as in-line warming. The device, however, is made with a technology that prevents any loss of heat but it does not provide heat retaining methods.

Once you raise the temperature to the one required which is thirty-seven degree Celsius, you transfuse the fluid into your body since when you don't do it, it will naturally cool down to where the temperature was initially. Additionally, it can provide heat without interfering with the living cells like WBC and RBC.

Nevertheless, they are able to provide heat and warmth to this fluid without affecting the functioning and structure of living cells like white and red blood cells as well as other cells. These devices are therefore important and are usually used during transfusion of large amounts of blood such as half or above half of the whole body volume. They also play important role in providing the necessary temperature when transfusion is to be done in a rapid manner.

However, you need to consider specific things before you administer the process to the patients who are neonates, elderly, pediatric, as well as those who have cardiac dysfunction and chronic infections. You need to operate the device before you start the entire exercise since it cannot be switched on, and on the other hand it will provide the temperature you require.

The devices are supposed to be in operation mode prior to the exercise so as to provide temperature rise in a gradual and systematic way not in a random way that can affect the cells. When properly utilized, negative effects associated with cold temperature will not be experienced. The devices, on the other hand, are not disposed after a single use as they are reused. They are also convenient devices more the countercurrent that requires auto start-stop to keep the required temperature.

However, they are drawn back by aspects like failure to have temperature maintenance ability. The only way to keep the fluid warm is by constant functioning, once switched off, they cannot maintain the attained temperature.

Additionally, it does not mean that the body temperature will rise when you infuse the warm fluids in your bloodstream. They are just therapeutic options for offering warmth.
