Table 2 Respiratory rate, blood gas analysis at inclusion, and main initial ventilator settings

From: End-tidal carbon dioxide monitoring using a naso-buccal sensor is not appropriate to monitor capnia during non-invasive ventilation

  1. RR, respiratory rate; SaO2, oxygen saturation in arterial blood; PaCO2, carbon dioxide partial pressure in arterial blood; PaO2, oxygen partial pressure in arterial blood gas; PaO2/FIO2, oxygen partial pressure in arterial blood gas over inspired fraction of oxygen ratio; IPAP, set inspiratory pressure; EPAP, set expiratory pressure.
