HumidITI Study

HumidITI logo that includes water droplet

All very preterm babies admitted to the NICU are cared for in incubators with humidity. This method has been the accepted practice for several decades. However, doctors and nurses are unsure of how much humidity to use.

This study compares commonly used humidity settings in incubators for infants <25 weeks’ gestation. Results from the study will inform the approach used in our NICU and other NICUs.
