Efficacy On The Use Of High Flow Nasal Cannula In De Novo Acute Hypoxemic Respiratory Failure

Background:(AHRF)is one of the leading causes of morbidity and mortality among patients presenting to the Emergency Department and Intensive Care Units.Evidence regarding the use of Non-Invasive Ventilation(NIV)in the management of patients with acute hypoxemic respiratory failure remains inconclusive.However,recent data is now available,encouraging the use of a high-flow nasal cannula(HFNC)as a practical alternative to conventional oxygen therapy in the management of patients with AHRF.Question:What is the efficacy of High Flow Nasal Cannula(HFNC)in patients with de novo acute hypoxemic respiratory failure?Aim:This study aims to elucidate clinical benefits regarding the use of high flow nasal cannula in de novo acute hypoxemic respiratory failure at the emergency department.Methodology:Study design:A narrative review.Keywords:efficacy,high flow nasal cannula,high flow oxygen nasal therapy,de novo acute hypoxemic respiratory failure,and acute hypoxemic respiratory failure.Results:This review focused on current evidence on the clinical benefits of the use of high flow nasal cannula in the management of patients with acute hypoxemic respiratory failure.These clinical benefits include decreased mortality and intubation rate,improved oxygenation and comfort,and increased treatment success rate.Conclusion:HFNC is a well-tolerated treatment method and offers several advantages in patients with de novo AHRF;hence may be used as a first line treatment method in these kinds of patients.
