PEEP

Positive end-expiratory pressure A therapeutic modality consisting in the active–interventional maintenance of a slightly positive pressure in the tracheobronchial tree during assisted pulmonary ventilation, such that alveoli are not allowed to completely collapse between breaths; PEEP is of greatest use in ARDS and generated by attaching an airflow threshold resistance device to the expiratory port of the non-rebreathing valve of a manual or mechanical ventilator, allowing a ↓ of airway pressure to a plateau level Conventional PEEP Pressure is maintained at 5-20 cm H₂O; it is indicated where an inhaled oxygen fraction at 0.6 cannot maintain the PaO₂ above 60 Torr High PEEP Pressure is maintained at 20-50 cm H₂O; it is used for marked hypoxia, as may occur in severe pulmonary edema
