======Automatic Mechanical Ventilation Control (AMVC)======
**Last updated: 04/20/2022**


======Summary======
We would like to propose a solution that uses an RL agent to make input decisions for PCVs(Pressure Controlled Ventilatior).

  * **Mentor(s):** Antwan D. Clark

You may want to include a picture or two here.

======Background, Specific Aims, and Significance======
Pressure Controlled Ventilation has several points that are crucial to being implemented correctly. The parameters must be set to achieve a certain tidal volume. Given that this is not one of the direct inputs, it will require calculations. Extra attention must also be given to the max pressure value set to avoid barotrauma.

======Deliverables======
 
  * **Minimum:** (Expected by 4/6)
    - build a reliable mathematical lung model and a PCV model
    - train a RL agent that automatically makes decisions to adjust the parameters

  * **Expected:** (Expected by 4/14)
    - initial proof of concepts of MDP in ventilator controller
    - documented code and performance metrics.

  * **Maximum:** (Expected by 4/28)
    - Conference paper


======Technical Approach======
With mathematical models of lung(multi-componential models), we could have an reliable simulation for lung reaction.  (RL environment)
Change pressure control ventilator settings(RL action) to adjust the state of lung (Flow, Pressure, Volume, etc : RL agent state)
Use MIMIC-III dataset and Survival Analysis to evaluate the cost/reward of RL actions 

======Dependencies======
  * MIMIC III Impact: on Training Results and Evaluations (Completed)
  * Computing Resources Impact: Training the Network and Accessing the Database
  * Interface Between Python and Matlab Simulink : A larger workload for migrating Model to Python (Completed)
