Abstract

Bedrest is an enforced condition for the patient to lie in bed. The patient is restricted to limited activities due to disease or disorders of the body's organs that are either physical or mental needing long term recovery. This situation has a negative impact such as an increase in temperature in the back area of the body that is in direct contact with the bedding. An increase in body temperature between the patient's body and the bedding can cause the patient's skin to become redder, to swell, prone to skin peeling, and thus making it more susceptible to infection. The use of common mattress in bed rest patients can potentially have a worse impact, such as the occurrence of decubitus. Decubitus injury is a damaged tissue, anatomical injury, and skin burning due to lying in bed over a long period of time. Therefore, a tool is required to overcome the problem by monitoring and reducing the temperature between the patient's body and the bedding. This proposed tool works by monitoring when the temperature between the patient's body and the mattress is detected ? 33°C, the tool will automatically cool the surface of the bed so that it can reduce the temperature between the patient's body and the bed. The targeted comfortable temperature of bedding/mattress used by patients in the tropical climate (such as Indonesia) is around 33°C to 35°C at a room temperature of approximately 25°C to 27°C.
