A cooling blanket is primarily used for managing hyperthermia, which is an abnormally high body temperature often due to illness, environmental factors, or overexertion. Cooling blankets work by promoting heat loss through conduction and convection, thereby effectively lowering the patient's body temperature to a safe range.

When hyperthermia occurs, the body can become overwhelmed by heat, leading to complications such as heat exhaustion or heat stroke. The application of a cooling blanket allows for a controlled and gradual decrease in temperature, helping to alleviate symptoms and prevent further health risks.

In contrast, hypothermia refers to subnormal body temperature, and cyanosis is the bluish discoloration of the skin due to inadequate oxygen levels. Shivering is a physiological response to cold, which serves to generate heat rather than to lower body temperature. Therefore, the use of a cooling blanket specifically addresses the needs of a patient experiencing hyperthermia.
