From: High-flow nasal cannula oxygen versus non-invasive ventilation in patients with acute hypoxaemic respiratory failure undergoing flexible bronchoscopy - a prospective randomised trial

Figure 4

PaO 2 /FiO 2 and PaCO 2 at baseline, pre and post bronchoscopy. Changes in PaO2/FiO2(A) and PaCO2(B). Values are given as mean and standard deviation. *P <0.05; n.s. not significant. FiO2, fraction of inspired oxygen; HFNC, high-flow nasal cannula; NIV, non-invasive ventilation; PaCO2, partial pressure of carbon dioxide in arterial blood; PaO2, partial pressure of oxygen in arterial blood.
