Dynamic hyperinflation, also called intrinsic PEEP (PEEPi,) occurs particularly when high tidal volumes or high respiratory rates are used during mechanical ventilation, although the phenomenon does occur at normal tidal volumes. It is not identified using existing monitoring such as the airway pressure but can be identified by occlusion of the expiratory port before the onset of the next positive pressure breath. Many factors contribute to PEEPi which has unfavourable effects on respiratory… CONTINUE READING
