Nursing in DI requires a set of advanced skills and as nurses working within a high tech environment, there is the opportunity to promote and to provide quality-nursing care to children. 
The nurses utilize physical assessment skills, perform guided risk assessments, and determine a sedation plan taking into consideration all potential risks to the patient. The care provided by our nursing team spans from initial assessment, to induction, monitoring and recovery.
