Current modes of conventional ventilation in intensive care
In practical terms, ventilation of critically ill patients should be established in the following way:
• Setting a level of PEEP that is adequate to keep the alveoli open (above the lower inflection point; Fig. 3)
• Ensuring that the maximum inspiratory pressure does not exceed 30 cmH2O (the upper inflection point), even if this results in small tidal volumes and permissive hypercapnia
• Ensuring that expiratory time is adequate to prevent gas trapping and intrinsic PEEP, by checking that the end‐expiratory flow returns to zero on the waveforms
• Accepting a PaO2 of 60 mmHg (8 kPa) when setting inspired oxygen.
