Pandemic / Emergency Ventilator with Autopilot

Mermaid Care has modified the BEACON Caresystem to perform Closed-Loop (Autopilot) ventilation on the Pandemic ventilator developed by Aalborg University in Denmark


What does "Autopilot" means?

It means that BEACON will automatically adjust the ventilator settings

The adjustment is based on the patient's physiological status and BEACONs estimation of the clinical benefit by balancing the competing goals of mechanical ventilation

We still show the Advice screen on BEACON even though we make the ventilator changes automatically.

We do this, so you can have full transparency of what is going on with the ventilation management

The advice screen will be shown for 10sec and then the ventilator settings will be changed automatically


You can also decide to run in semi-pilot mode. It means that BEACON will provide you advice, and then you have to click on "Apply" to implement the ventilator changes

Waveform screen

The pandemic ventilator without BEACON, does not have a waveform screen. BEACON offers you that.

The waveform screen shows the following information

  • Ppeak, Pplat, VO2 and VCO2 as values

  • Pressure (cmH2O) and Flow (l/min) as waveforms - automatically adjusted

  • The current ventilator settings 

  • An option to change the ventilator manually 

View current patient status 

The BEACON Simulation screen has several layers of information, relevant for your level of expertise and for the understanding of the patient status and ventilation management


On the left side of the screen, the Current and Simulated settings of the Ventilator are shown, where

  • Current is the actual settings of the ventilator

  • Simulated is a simulation functionality, where the user can simulate other ventilator settings than calculated 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 simulated 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,


BEACON has build-in physiological monitoring

What does that mean for your Hospital?

It means that you

  • don't need experienced staff to run and manage the ventilator - its done automatically. 

  • can reduce the patient's time on ventilation by up to 25% - meaning freeing up ventilator capacity

  • can protect your staff for contamination risk as they don't need to be near the patient when managing the ventilator

Autopilot mode

When we run in autopilot-mode we still show FULL transparency, so that your staff has insight to the management of the patient

Historical review of patient status

BEACONs Historical review screen shows all previous ventilator changes made by BEACON. The Historical review screen has several layers of information, relevant for your level of expertise and for the understanding of the past patient status

On the Historical Review screen all ventilator changes are shown by displaying the Hexagon for each  (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

With the physiological monitoring screen you can monitor the physiological variables of the patient:

  • FetCO2 and FeCO2 measurements

  • Anatomical (Vd-ana) and Alveolar (Vd-alv) deadspace measurements

  • VO2 and VCO2 measurements 

  • Gas-Exchange measurements shown as the SHUNT value (%), the Low V/Q value (delta PO2) and the High V/Q value (delta PCO2)


Optimizing Nutrition for the Covid-19 patient

  • 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

Ventilation specs

The Pandemic Ventilator is intended for treating patients with respiratory failure or insufficiency. The Pandemic Ventilator should only be used by professional health care personal trained in using this specific ventilator. The Pandemic Ventilator should only be used in hospital environments and other facilities with the primary purpose of treating respiratory complications. The Pandemic Ventilator can be used for transport between or within health care facilities.
