Hypovolemic shock occurs to trauma patients because of the loss of body fluid volume, which includes loss of blood, water, perspiration, etc. The effects of shock, especially due to major blood loss, rapidly become irreversible. Therefore, it is critical for medical professionals to begin interventions early in the prehospital setting in order to improve shock outcomes.
Among trauma patients, hypovolemic shock is commonly caused by haemorrhage, and particularly resuscitation-associated coagulopathy in haemorrhage shock has been recognised as the major cause of the Trauma Triad of Death (see Figure 1.). Together with coagulopathy, hypothermia, and acidosis are the three lethal complications in this triad.

The article (the link below) points out that prehospital IV Fluid warmers, peripheral warming devices and blankets are typically used to reduce hypothermia, and at present coagulopathy can be treated only with blood product through a warming infuser. It is highlighted that all blood products should be administered through a warming infuser just as IV fluids.
