The INVOS™ Patient Monitor, model PM7100, is a noninvasive cerebral/somatic oximetry system intended for use as an adjunct monitor of regional hemoglobin oxygen saturation of blood in the brain or in other tissue beneath the sensor. It is intended for use on individuals greater than 40 kg at risk for reduced-flow or no-flow ischemic states.
The INVOS™ Adult rSO2 Sensor is indicated for single patient use when cerebral/somatic monitoring of site-specific regional oxygen saturation (rSO2) is required in patients weighing >40 kilograms. This sensor is only intended to be used with INVOS™ Near Infrared Spectroscopy (NIRS) technology including monitoring systems and devices integrated with INVOS™ NIRS technology. For additional information regarding setup and use of the INVOS™ System including indications for use, contraindications, warnings and cautions, consult the Monitoring System Operator's Manual.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
