What is it indicated for?
CLEWICU provides the clinician with physiological insight into a patient’s likelihood of future hemodynamic instability. CLEWICU is intended for use in hospital critical care settings for patients 18 years and over. CLEWICU is considered to provide additional information regarding the patient’s predicted future risk for clinical deterioration, as well as identifying patients at low risk for deterioration. The product predictions are for reference only and no therapeutic decisions should be made based solely on the CLEWICU predictions.
Indications for use as stated in the FDA summary.
