The NxStage Connected Health System is for use by chronic hemodialysis patients remotely in combination with the NxStage System One and a variety of devices such as blood pressure monitor and weight scale upon the prescription of a licensed physician or healthcare practitioner. The Connected Health System serves as the data repository and communication link to the server software which is utilized by the healthcare facility. The healthcare facility may include the physician or licensed healthcare practitioner, other clinicians, or a disease management center.
The purpose of the system is to collect, accumulate, store and transmit medical information such as flowsheet data, vital signs, blood pressure, weight and dialysis data from the patient on the completion of their dialysis treatment and transmit these results to their healthcare practitioner at another facility. The system also provides online labeling, treatment status, trending and supports education and messaging.
The device is not intended to provide time sensitive data or alarms and does not control the System One Cycler. This system may not be used as a substitute for direct medical intervention or emergency care.
Interpretation of the information collected and transmitted requires clinical judgment by an experienced medical professional.
Indications for use as stated in the FDA summary.
