Systems, methods, computer storage media, and user interfaces are provided for dynamically associating and disassociating patients and medical devices. A signal communicated via a Bluetooth personal area network is received when a patient is in proximity to a medical device. In various embodiments, the signal originates with a patient wristband or the medical device. The medical device is automatically associated to the patient. When the signal is no longer being received, the medical device may be automatically disassociated from the patient. Data associated with the medical device may be communicated to an EMR associated with the patient. A mobile device associated with a clinician may be communicated with via the Bluetooth personal area network.
