It is expensive, frequently used, and not without risk. There is limited evidence supporting a standard approach to initiation and weaning.

We found a decrease in the percentage of CICU patients initiated on iNO from 17.8% to 11.8% after implementation of the iNO utilization pathway. We did not observe a change in iNO utilization between the pre- and post-iNO pathway eras in either the PICU or NICU.
