BioSign TM is an accessory to a multi-parameter patient monitor (bedside or ambulatory) or clinical information system and is indicated for use by health care professionals with those non-pediatric high dependency care patients for whom multi-parameter patient monitoring has been routine.

BioSign T M provides the clinician with a trend graph of the patient status index based on a weighted average of five vital signs namely heart rate, respiration rate, temperature, oxygen saturation and blood pressure. The patient status indexTM is a single measure of the patient's condition and represents how different the patient's vital signs are with respect to normality. BioSign TM is an adjunct to and is not intended to replace vital signs monitoring

Indications for use as stated in the FDA summary.
