This gas was taken at 10 a.m. today when Mrs Smith was on 15l per minute of oxygen via a non rebreathe mask. Patients suffering from COPD exacerbation, regardless of whether they have CO2 retention, generally have supra-normal respiratory drive (unless there is impending hypercapnic coma), In COPD, patients optimise their gas exchange by hypoxic vasoconstriction leading to altered alveolar ventilation-perfusion (Va/Q) ratios, Excessive oxygen administration overcomes this, leading to increased blood flow to poorly ventilated alveoli, and thus increased Va/Q mismatch and increased physiological deadspace, this increase in Va/Q mismatch occurs in both CO2 retainers and non-retainers, the difference is presumably one of degree, deoxygenated hemoglobin (Hb) binds CO2 with greater affinity than oxygenated hemoglobin (HbO2), hence oxygen induces a rightward shift of the CO2 dissociation curve, which is called the Haldane effect, in patients with severe COPD who cannot increase minute ventilation, the Haldane effect accounts for about 25% of the total PaCO2 increase due to O2 administration, the targeted approach is associated with decreased mortality in COPD patients and less respiratory acidosis, The oxygen flow rate administered is not important, the (alveolar) PAO2 (and, indirectly, the SaO2) achieved is, Never withhold oxygen from a seriously ill hypoxic patient due to fear of cause hypercapnic respiratory failure.

Acute type 2 (hypercapnic) respiratory failure is a potentially life-threatening complication that is more likely to develop in patients with certain underlying conditions. Patients suffering from COPD exacerbation, regardless of whether they have CO2 retention, generally have supra-normal respiratory drive (unless there is impending hypercapnic coma) Respiratory failure is a condition in which the respiratory system fails in one or both of its gas exchange functions, i.e. The presence of paradoxical breathing points to various types of respiratory distress or respiratory failure.
