What is the primary purpose of an air mattress in patient care?

An air mattress is specifically designed to prevent bedsores, also known as pressure sores or decubitus ulcers. These injuries occur due to prolonged pressure on the skin, particularly in individuals who are bedridden or have limited mobility. The primary function of an air mattress is to redistribute weight and relieve pressure points on the body. By using alternating air cells that inflate and deflate, the mattress helps maintain proper blood circulation, thereby reducing the risk of skin breakdown. This is especially crucial for patients who may have compromised skin integrity or are at higher risk for developing pressure ulcers.

While enhancing comfort during sleep and regulating body temperature may be beneficial features of air mattresses, their fundamental purpose in patient care is to prevent the development of sores. Thus, a mattress's role in providing extra support for mobility is secondary and not its primary function. Understanding this helps caregivers prioritize pressure ulcer prevention in their care routines.
