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:
- Spontaneous or controlled mode
- Pressure or volume controlled
- Peak and plateau pressure
- Tidal volume
- I:E ratio
We will now discuss these in turn.
