According to the retired AARC Clinical Practice Guidelines on time-triggered,pressure- limited,time-cycled neonatal ventilation,which is true of the use of PEEP?
I.Used to decrease FRC
II.Used to improve oxygenation
III.Typically set between 4-7 cm H2O
IV.Above 7 cm H2O can result in hyperinflation

Question

Quizplus · Accepted Answer

PEEP increases FRC and may improve oxygenation and ventilation-perfusion relationship.PEEP is typically adjusted at 4-7-cm H₂O.Levels beyond this range may result in hyperinflation,particularly in patients with obstructive airways disease (e.g.,MAS or bronchiolitis).
