Mechanical ventilation

How to set up a ventilator

The purpose of ventilation is to provide ‘life support’ without causing harm to the lungs and the patient. A major form of harm is ventilator induced lung injury (VILI).

As the patient arrives in ICU, we need to decide on the setting the following:

  • FiO2
  • PEEP
  • Spontaneous or controlled mode
  • Pressure or volume controlled
  • Peak and plateau pressure
  • Tidal volume
  • I:E ratio

We will now discuss these in turn.
