How do you fix a beak wave form on the ventilator?

• A. Increase Vt
• B. Increase PIP
• C. Reducing Vt or PIP
• D. Increase RR

Answer: (C)

A beak-shaped waveform usually signals that the lung is being driven with too much pressure or volume, causing overdistension and a distorted inspiratory graphic. The way to correct it is to lower what’s delivering that peak—either by reducing tidal volume or reducing peak inspiratory pressure. By dialing back the amount of air the ventilator pushes into the lungs (lower Vt or lower PIP), the peak forces that create the beak decrease, and the waveform returns to a smoother, more normal appearance. Raising tidal volume or increasing peak inspiratory pressure would tend to exaggerate the distortion, and changing the respiratory rate doesn’t address the shape of the inspiratory limb.
