Solution
Controlled hypothermia:
Controlled hypothermia is a type of clinically induced hypothermia used to lower a structure's or the entire body's metabolic rate.
When controlled hypothermia is utilised in a clinical setting, the patient is given medication to reduce shivering before the body is chilled.
The body engages in a continuous series of coordinated physiological activities in order to maintain a constant temperature.
These disorders are frequently found in open-heart surgery because it lessens the metabolic demands of the heart lowering the chance of injury.
When the heart stops, an external heart-lung pump keeps the body's circulation going.
Throughout the surgery, the heart is cooled and kept at a temperature below 15°C.
The heart muscles are able to survive a lack of blood supply due to the cold temperature.
