Model 8203CA
The Model 8203CA single-patient use, non-sterile, disposable sensor is intended for use as an adjunct monitor of trends in regional hemoglobin oxygen saturation of blood underneath the sensor of adult or pediatric patients weighing greater than 88 pounds (40 kilograms). The sensor may be repositioned or replaced with another 8203CA sensor without baseline re-establishment. It is intended for use in environments including the operating room, surgical recovery, critical care, emergency room, long-term care, and mobile environments.
Model 8204CA
The Model 8204CA single-patient use, non-sterile, disposable sensor is intended for use as an absolute real-time adjunct monitor of regional hemoglobin oxygen saturation of blood underneath the sensor of adult and pediatric patients weighing greater than 88 pounds (40 kilograms). The sensor may be repositioned or replaced with another 8204CA sensor without baseline re-establishment. It is intended for use in environments including the operating room, surgical recovery, critical care, emergency room, long-term care, and mobile environments.
