The Clinical Disease Severity Score (CDSS) can be used to determine the severity of a respiratory syncytial virus (RSV) infection in an infant or child.
Patient selection: infant or child with RSV
Parameters:
(1) transcutaneous oxygen saturation in percent
(2) respiratory rate in breaths per minute
(3) retractions
(4) chest auscultation
(5) activity
