The effectiveness of Continuous positive airway pressure can be determined by evaluating which of the following criteria
I.Decreased work of breathing
II.FiO₂ requirements less than or equal to 0.40
III.Improved lung volumes via chest radiograph
IV.PaCO₂ greater than 55 mm Hg
V.Nasal flaring evident
VI.No grunting audible

Question

Quizplus · Accepted Answer

The effectiveness of continuous positive airway pressure can be determined by evaluating decreased work of breathing, improved lung volumes via chest radiograph, and no grunting audible. Nasal flaring and FiO₂ requirements greater than 0.4 are signs of respiratory distress and indicate poor outcomes. A PaCO₂ greater than 55 mm Hg indicates respiratory failure and poor effectiveness of CPAP. Therefore, option C is the correct choice.
