I understand that you want to simulate a simple medical ventilator using Simscape/Simulink that involves creating a model that captures the dynamic behavior of the system, including the blower (or pump), the resuscitation bag, and the lung simulator.
The blower can be represented by a pressure source in Simscape. This will simulate the blower providing airflow to the system.
- In the Simulink Library Browser, navigate to Simscape > Foundation Library > Gas > Sources.
- Drag and drop a "Controlled Pressure Source" block into your model. This will act as your blower.
The resuscitation bag can be modeled as a variable volume with compliance, representing its ability to expand and contract. You might need to use a combination of Simscape blocks to achieve this.
- Navigate to Simscape > Foundation Library > Gas > Elements.
- Use the "Constant Volume Chamber" block or a similar component that can represent the compliance of the bag.
The lung simulator can be modeled using components that simulate the compliance (elasticity) and resistance (airway resistance) of human lungs.
- For compliance, use a "Constant Volume Chamber" block.
- For resistance, use a "Flow Resistance" block from the same library.
- Connect these blocks in series to represent the lung simulator. Adjust their parameters based on the physiological properties you want to simulate.
Please refer to the provided documentation, which I believe will be helpful for your implementation:

Hope it helps!
