A patient monitoring hub can communicate bidirectionally with external devices such as a board-in-cable or a dongle. Medical data can be communicated from the patient monitoring hub to the external devices to cause the external devices to initiate actions. For example, an external device can perform calculations based on data received from the patient monitoring hub, or take other actions (for example, creating a new patient profile, resetting baseline values for algorithms, calibrating algorithms, etc.). The external device can also communicate display characteristics associated with its data to the monitoring hub. The monitoring hub can calculate a set of options for combined layouts corresponding to different external devices or parameters. A display option may be selected for arranging a display screen estate on the monitoring hub.

A metallic diaphragm disk incorporating a piezoelectric material bonded thereto and operatively coupled to a base rim of a housing provides for closing an open-ended cavity at the first end of the housing. At least one inertial mass is either incorporated in or attached to the housing. A plastic film adhesively bonded to at least one of an outer rim of the housing or an outer-facing surface of the disk provides for receiving an adhesive acoustic interface material to provide for coupling the housing to the skin of a test subject.

Example headsets and electrodes are described herein. Example electrode units described herein include a housing having a cavity defined by an opening in a side of the housing and an electrode. In some such examples, the electrode includes a ring disposed in the opening and an arm, where the arm has a first portion extending outward from the opening away from the housing and a second portion extending from an end of the first portion toward the housing and into the cavity, and the first and second portions connect at a bend.

A portable device is configured to connect directly to an intraosseous (IO) catheter and provide a clinician with actionable information to determine whether the catheter is placed correctly, such as whether the catheter is placed in the medullary cavity of bone. The device provides this information leveraging the presence or absence of arterial pressure waveforms. A method for assessing placement of an intraosseous catheter includes coupling a pressure transducer to an IO catheter placed in tissue, obtaining a continuous pressure waveform from a pressure signal provided by the pressure transducer, and assessing placement of the catheter based on the continuous pressure waveform.

Various smart medical connection embodiments of the present disclosure encompass a magnetic connectivity manager energizing ferromagnet(s) in response to a powering on the magnetic connectivity manager and a sensing of a connection strain on a medical base (21) and/or a patient base (31) of the device, whereby a magnetic connectivity interface (22, 32) activates a magnetic connectivity between metallic module(s) and the ferromagnet(s) for interfacing the conduit channels of the bases. The various smart medical connection embodiments of the present disclosure further encompass the magnetic connectivity manager deenergizing the ferromagnet(s) in response to a powering down of the magnetic connectivity manager and/or a sensing of a disconnection strain on the base(s), whereby the magnetic connectivity interface (22, 32) deactivates the magnetic connectivity between the metallic module(s) and the ferromagnet(s) for interfacing the conduit channels of the bases.
