It was Claudio Castillano Lévano, from Peru, who helped save the lives of thousands of babies. Lévano realized the death rate of high-risk premature babies born in the Caribbean and Latin America was too high. The Peruvian set to work on a portable incubator and respirator. Called a neonatal artificial bubble, it regulates temperature and keeps babies away from contamination risks. The bubble provides a protective and sterile wrap for the newborn. Extra oxygen can be administered, and the bubble protects premature babies with a risk of infection, hypothermia, or other complications. The bubbles are used in neonatal intensive care (NICU) units, providing a sterile, warm, and oxygen-enriched environment.
