BODYGUARDIAN CONTROL UNIT – BASE KIT Operator Manual

The upload frequency depends on the Configuration Specifications. The

Bodyguardian Control Unit is equipped with an internal memory capable to store

up to 24 hours of data recording, enabling the device to work as an Holter

equipment.

4.2.2 STREAMING MODE

In Streaming mode the Bodyguardian Control Unit operates as an acquisition and

transmitter of the physiological data. The acquired signals are not stored in the

internal memory of the device but are sent directly from the Bodyguardian

Control Unit to the Associated Device according to the configuration parameters

received from the Associated Device during the configuration settings. The

Associated Device is responsible for forwarding the data to a remote storage

server for later analysis and evaluation.

In Streaming Mode the Bodyguardian Control Unit can acquire and transmit the

following data, depending on the configuration received:

Raw signals:

o ECG (128 or 256 Hz)

o 3-axis accelerometer (50 Hz)

o dZ bioimpedance (32 Hz)

o Z0 bioimpedance (32Hz)

Derived values:

o Heart rate values,

o Heart rate reliability,

o Breathing rate values,

o Activity level,

o RR interval variability,

o Body position values.

4.2.3 EVENT MONITORING

The Bodyguardian Control Unit has the capabilities to register symptomatic and

asymptomatic events during the functionalities.

Symptomatic Events recording: while wearing the Bodyguardian Control Unit

the user has the possibility to initiate an event recording, if is feeling symptoms

that suggest the need for further evaluation, by pressing the push button in the

middle of the device. The functionality is enabled either in Monitoring or

Streaming Modes. In case of symptomatic event button push, Bodyguardian

Control Unit will send a notification of the event to the Associated Device. If the

Associated Device is not available, the Bodyguardian Control Unit will retry

according to implementation and configuration requirement and eventually store

in the internal memory the undelivered notifications.
