Moreover, the need for ventilatory support (in one in five patients) and high in-hospital mortality (11%) followed use of high-flow oxygen. 4 Two more recent audits of COPD admissions in the United Kingdom that involved 9 patients, respectively, 3, 5 reported associations between acidosis and the use of high Fi o 2. Yet this dangerous practice continues, putting patients at risk of loss of life and using substantial health system resources.ĭangers of using high Fi o 2 for patients with COPD were well-documented 60 to 70 years ago. However, high Fi o 2 has been shown to be dangerous for patients with COPD, and guidelines advise against its use. 3 It may seem intuitively right to put a “blue” patient on a high concentration of inspired oxygen (Fi o 2). ![]() Uncompensated elevated Pa co 2 causes respiratory acidosis, and acidemia can be deadly. 2 The highest costs were for patients with COPD who were admitted to the intensive care unit (ICU), with a substantial association between costs and elevated partial pressure of carbon dioxide in arterial blood (Pa co 2). A decade later, new data from the Ottawa Hospital, which spent about $20 million on first-time admissions for COPD ( n = 1894) over four years, has shed more light on the reasons for this cost burden. 1 Acute exacerbation of COPD is still the primary reason for an adult hospital admission in Canada. Annual costs related to admissions to hospital for acute exacerbation of chronic obstructive pulmonary disease (COPD) were reported in 2007 at $750 million. ![]()
