What can occur if there is a sudden power failure in an incubator?

A sudden power failure in an incubator can lead to a decrease in temperature. Incubators are designed to maintain a specific temperature range that is essential for the proper growth and development of organisms, particularly in neonatal care for infants. When the power is disrupted, the heating element that maintains the incubator's temperature can no longer function, causing the temperature inside to drop rapidly.

This decrease in temperature can be particularly dangerous for infants, especially premature or critically ill neonates who rely on controlled thermal environments to prevent hypothermia, which can lead to various complications.

While an increase in humidity might occur if the incubator has a water reservoir that doesn't have a power source to circulate, the predominant and critical issue during a power failure is the inability to maintain the necessary temperature. The other options, such as stabilization of O2 levels and improved thermal stability, do not necessarily result from a power failure and can be misleading in the context of an incubator's primary function.
