1. A system for use in assisting a user during a medical event, the system comprising:
a patient monitor; and
a mobile device including:
a camera;
at least one processor; and
a non-transitory machine-readable medium storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
obtaining, from the camera, an image of a visual code presented on the patient monitor;
extracting an identifier associated with the patient monitor from the obtained image; and
establishing a communication channel with the patient monitor using the extracted identifier, wherein the communication channel is configured to use proximate tokens between the patient monitor and the mobile device, wherein the proximate tokens for determining spatial localization is mutually known by the patient monitor and the mobile device without requiring transmission to the other device, and wherein the proximate tokens are used in a key-exchange protocol.
