Fig 2. AutoPEEP phenomena.

Fig 2

Schematic illustration of a severe AutoPEEP phenomena with repetitive AutoPEEP related frustrating inspirational efforts registered by polysomnography in a patient ventilated in an assisted mode. Inspirational efforts of the thorax and abdomen occur regularly (asterisk). No inspiration signal in the pneumotachographic channel is triggered, but expiratory flow is slowed (black arrows) and then accelerated (white arrows). The pressure channel registers a small peak (arrow head), resulting from a boosted expiratory flow.
