What settings do you adjust to affect VENTILATION?

Increasing PS (IPAP-EPAP) will increase minute ventilation
What settings do you adjust to affect OXYGENATION?
- Increasing FiO2 to increase oxygenation
- Increasing EPAP (Don’t forget to increase IPAP to keep the same PS) to increase oxygenation
when you increase epap you also gotta increase ipap to keep the same
