Advisory system for ICU Ventilation
BEACON provides ventilator-dependent open-loop advice for optimizing and weaning-off ICU ventilated adult patients.
BEACON uses inputs measured and data inputs from the ventilator and manual data entry by the clinician into a computer program that has been designed to assist clinical decisions for changes to the ventilator settings for the individual patient undergoing mechanical ventilation.
The objective of the BEACON Caresystem is to present advice for ventilator adjustment and the rationale behind the advice, in a clear and easy-to-use graphical format.

Simple and Clear Advice Screen
BEACON continuously monitors the patient, and provides advice at any given time. The advice is given in a simple and clear format as shown below.
A) Each of the ventilator settings (FiO2, Vt, Rf etc) are shown according to Ventilator brand. B) The current Ventilator settings are shown. C) BEACONs ventilator advice is shown
The advice is applied by changing the ventilator settings on the ICU ventilator (note: BEACON is open-loop)
Explore the Reason behind the Advice
BEACONs Simulation screen explains the reason behind the advice provided by BEACON. The Simulation screen has several layers of information, relevant for your level of expertise and for the understanding of the advice

On the left side of the screen, the Current, Simulated and Advice settings of the Ventilator are shown, where
-
Current is the actual settings of the ventilator
-
Advice is the new advice calculated and provided by BEACON
-
Simulated is a simulation functionality, where the user can simulate other ventilator settings than advised by BEACON
On the right side of the screen, the Hexagon is shown. The Hexagon shows the balance of over- and under-ventilation of the current and advised ventilator settings for the patient:
-
Too much oxygen vs too little oxygen,
-
Too much pressure vs. too little pressure, and
-
Too much support vs too little support,

Historical review of All Advices
BEACONs Historical review screen shows all previous advices provided by BEACON. The Historical review screen has several layers of information, relevant for your level of expertise and for the understanding of the past advices

Spontaneous Breathing Test
BEACON has built-in an automatic Spontaneous Breathing Test (SBT). When certain conditions are met, the SBT will be initiated by BEACON automatically

ECMO Transfer
BEACON has built-in an automatic recommendation for ECMO transfer. When certain conditions are met, the ECMO recommendation will be initiated by BEACON automatically
Shunt, Low V/Q & High V/Q Estimation
BEACON can be used to estimate the Gas-Exchange characteristics for the patient. It is shown as the SHUNT value (%), the Low V/Q value (delta PO2) and the High V/Q value (delta PCO2). This can be very useful, if a PEEP ti-tration maneuver is carried out and you want to verify the effect of the different PEEP levels.
Indirect Calorimetry
BEACON can be used to guide Nutrition by using the Gas Exchange measurements VO2/VCO2 and the calculated REE

The user can explore the values behind each ventilation measures (label) of the Hexagon
Each Hexagon label window contains values related to:
-
The Pressure/Volume balance of over/under ventilation (Support and Control Mode)
-
The Oxygenation balance of over/under ventilation (Support and Control Mode)
-
The Support balance of over/under ventilation (Support Mode only)
If the user wants to understand the current state of all organs related to ventilation management, then this is shown Physiology information window. The information is divided into organs:
-
Lung:
-
Gas Exchange
-
Volume/Ventilation
-
Mechanics
-
-
Brain
-
Blood
-
Metabolism
-
Circulation
The user can simulate other ventilator settings than advised by the system and see the impact on the ventilation measures
This can be useful, in order to understand the effects of other ventilators settings before applying them
This can also be useful for bedside training, where residents are being trained on patients rather than on simulation systems.
On the Historical Review screen all advices are shown by displaying the Hexagon for each advice (2 are shown in this example)
The Historical review screen is very useful during ICU rounds, in order to provide the ICU Doctor and/or Respiratory Therapist with a simple overview of how the patient has progressed over time
For each Hexagon, information about ventilator settings and changes can be shown
For each Hexagon, information about the patient's physiological status can be shown
The information is divided into organs (similar to the Physiological information window on the Simulation screen:
-
Lung:
-
Gas Exchange
-
Volume/Ventilation
-
Mechanics
-
-
Brain
-
Blood
-
Metabolism
-
Circulation
.png)
The Gas Exchange information screen displays the estimated (measured) SHUNT, Low V/Q and High V/Q for the patient
The Graph display of BEACON, shows the VO2, VCO2, REE and RQ:
-
VO2 - is the measured Oxygen Consumption of the patient
-
VCO2 - is the produced Carbon Dioxide production of the patient
-
REE - is the calculated Resting Energy Expenditure of the patient, based on the VO2 and VCO2 measurements
-
RQ - is the calculated difference between VO2 and VCO2
For VO2 and VCO2, the average Variable in % is shown over a time window of 30 minutes
For REE, the current REE is shown and average REE is shown over a time window of 30 minutes
Based on the REE, BEACON provides advice for Nutrition

When certain conditions are met, the SBT indicator (lower left corner) will be shown. The indicator contains a counter, which shows how long time the SBT will run.
If the SBT passes, the SBT indicator will be shown in green ad n with a check mark.
The conditions for initiating and passing the SBT, can all be configured in BEACON.
When certain conditions are met, the ECMO recommendation (yellow warning) will be shown.
The user can enable the ECMO screen of BEACON, and verify which ECMO conditions are met, and acknowledge ECMO status for the patient.
The conditions for recommending ECMO, can all be configured in BEACON.
