Efficiency of HFNC Vs NIV in Patient With Acute Type 2 RF

Background: In acute hypoxic respiratory failure, high-flow nasal cannula (HFNC) oxygen treatment is gaining popularity. However, there is just a small body of research to back up the use of HFNC in acute respiratory failure (ARF) with hypercapnia. Aim of study: To evaluate the effectiveness of high-flow nasal cannula (HFNC) in reducing the rate of endotracheal intubation and PCO2 level in adult patients with Acute moderate type II respiratory failure in comparison to noninvasive positive pressure ventilation (NIPPV). Methods : A randomized control trial that was conducted on patients with acute moderate hypercapnic respiratory failure ARF (arterial blood gases pH 7.25-7.35, PaCO2\>45 mmHg) who were admitted to respiratory and medical critical care units from September 2020 through February 2022 and received HFNC or NIV .The endpoint was treatment failure, which was indicated by either invasive ventilation or mortality .
