Ventilator

How Do Ventilators Work?


Ventilators are respiratory regulation devices. They help relieve stress on injured or weakened lungs and help in oxygenation by sending a mixture of gases into the lungs. These gases, usually air and oxygen, are put under positive pressure to assist in inhalation and, if necessary, negative pressure to pull air out for exhalation. This ventilator design incorporates flow sensors, temperature sensors, a nebulizer and a humidifier to ensure the necessary amount of air is administered under proper conditions. 

Medical Respiratory Motor Control with Real Time Graphical Display 

Our Respiratory Equipment Demo provides core functions and components of the BLDC motor drive solution and closed-loop control mechanisms for CPAP and ventilator applications.

The demo showcases different modes to put air/gas into a patient based on the following fundamental principles and parameters:

  • Pressure: Inflate user to a certain pressure
  • Volume: Put a certain amount of volume into user
  • Respiratory Rate: Number of breaths per minute
  • Flow Rate: Motor RPM speed
  • Time: Inhalation and exhalation time length
  • Ramp Rate: Get the pressure/volume slowly or quickly

The demo uses a flow and pressure sensor to monitor flow and pressure and controls a BLDC motor to maintain the target flow, pressure or volume.

Considerations for Ventilator Designs


When designing ventilators, you should consider the following:
  •  Cost-efficient, highly integrated microcontrollers (MCUs) and microprocessors (MPUs) that can lower the Bill of Materials (BoM) cost of ventilator designs with integrated features such as analog signal conditioning, industry-leading connectivity and peripheral options
  • Highly accurate, programmable and selectable hysteresis temperature sensors
  • A variety of CryptoAuthentication™ secured connectivity devices such as Bluetooth®, Wi-Fi® and Ethernet
