## Indications for use
The HANC™ Network is intended to be used as a clinical tool to provide a method of monitoring a patient's health status at home and a method for transferring the data to a nurse for review. The HANC™ Network is indicated for use for patients that require medical observation and monitoring while at home, who have medication or therapy compliance issues, and who need training reinforcement. The HANC™ Network is not a patient emergency response system. It does not analyze patient information and does not offer medical advice to the patient. It collects, stores, and transmits patient information to the health professional.
