The medical management of patients with acute respiratory failure will vary depending on the cause and type of failure. In hospital it can develop as the result of inappropriate oxygen therapy and is therefore often preventable. After finishing his medical degree at the University of Auckland, he continued post-graduate training in New Zealand as well as Australia’s Northern Territory, Perth and Melbourne. All patients with type II respiratory failure that were deemed by the treating physician to require ventilatory support either with non-invasive ventilation (NIV) or High-Flow Nasal Cannula (HFNC). CHF) Type 2: Ventilation = Hypercarbic (i.e COPD) Two Settings on NIV to Improve Hypoxemia: Increase FiO2 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. Type 2 Respiratory Failure (hypercapnic): occurs when alveolar ventilation is insufficient to excrete the carbon dioxide being produced. Pulmonary hypertension. Defined as the buildup of carbon dioxide levels (P a CO 2) that has been generated by the body but cannot be eliminated.
