During HFOV, which of the following factors has a direct influence on a neonate's delivered tidal volume?

Question

Quizplus · Accepted Answer

During HFOV, peak and trough pressures are measured, although they are not usually displayed. Because of the impact of the ETT on transmitted pressure, these values have only relative significance. Of more importance is the difference between peak and trough pressures, known as oscillatory amplitude or simply the delta P. Delivered volume is directly proportional to this peak-trough difference, and adjustments result in changes in tidal volume.
