What keeps a premature baby alive in the incubator?

A premature baby is kept alive in an incubator through controlled environmental conditions that provide warmth, humidity, and oxygen. The incubator helps maintain the baby's body temperature, as premature infants often lack the body fat necessary for thermoregulation. It also supports respiratory function by delivering a regulated oxygen supply and reducing the risk of infections through a sterile environment. Additionally, the incubator allows for continuous monitoring of vital signs and care interventions.
