Patients with acute respiratory failure (PaCO 2 ≥ 55 mm Hg) superimposed on chronic obstructive lung disease are likely to develop severe hypercapnia (PaCO 2 ≥ 80 mm Hg) or acidosis (pH < 7·30 if given oxygen at a rate of 2 l. or more per minute via an Edinburgh mask of intranasal catheter. If oxygen is given via these devices, it should be at a flow rate of 1 l. per minute or less. The safest mask for the administration of oxygen to patients with acute respiratory failure is believed to be the 24% “Ventimask” used with a rate of 4 l. of oxygen per minute.
