NOT an AGMP
more comfortable
pt can eat and drink
precise O2 concentration
decreased WOB
promotes ciliary movement and secretion clearance

33
Q

What is PSI?

A

What’s left in the tank

34
Q

What patients is the oropharyngeal airway used on?

A

Only patients with altered LOC (stimulates gag reflex)

35
Q

How often is mouth care provided with oropharyngeal

A

Q2H or as per protocol (may need suctioning PRN)

36
