Abstract

Background: Acute respiratory failure (ARF) is one of the most common causes of intensive care unit (ICU) admission and in-hospital mortality. In South Korea, about 25% of patients admitted to the ICU require mechanical ventilation. The in-hospital mortality rate of these patients is 48%. Respiratory failure can be categorized based on pathophysiologic derangements, and the treatment options vary depending on their classification. This study discusses the status and treatment strategies of patients with ARF in Korea.
Current Concepts: The most common treatment for ARF was conventional oxygen therapy, being used at least once in 7.0% of all admitted adult patients and 85.1% of patients admitted with respiratory failure. High-flow oxygen therapy was required in 1.4% of all admissions and 17.2% of respiratory failure-related admissions. High-flow oxygen therapy was attempted in 19.1% of patients who needed invasive mechanical ventilation. Non-invasive positive pressure ventilation (NIV) was used in 0.4% of all admissions and 5.1% of respiratory failure-related admissions. Hypercapnic respiratory failure (57.1%) was the most common reason for NIV use. Invasive mechanical ventilation was required in 2.8% of all admissions and 33.8% of respiratory failure-related admissions.
Discussion and Conclusion: Despite its clinical significance, no large-scale studies have been performed on the etiology, treatment, and prognosis of patients with ARF in South Korea. A multicenter or a Korean National Health Insurance Service database study is necessary to accurately identify the characteristics, diagnose problems, and develop treatment guidelines for patients with ARF in South Korea.
