Q

Discuss setting

A

reasonable to start at 8-10cmh20 IPAP
4-6cmh20 EPAP
fi02 1

Once patient tolerating able to change pressures as needed
Changing IPAP or EPAP depends on whether ventilation or oxygenation is the primary problem

If persistent acidosis check
-circuit leak, wrong size mask 
-expiratory valve wongly fitted 
- is the patient rebreathing 
-failure to synch with ventilator 
If non of the above increase IPAP by increments of 2

If persistant hypoxia increase fio2 to 1 or increase EPAP
