The correlation between lung ultrasound scores and outcomes of high-flow nasal cannula therapy in infants with severe pneumonia.

Objective: The study aimed to explore the effectiveness of bedside lung ultrasound (LUS) combined with the PaO/FiO (P/F) ratio in evaluating the outcomes of high-flow nasal cannula (HFNC) therapy in infants with severe pneumonia.

Methods: This retrospective study analyzed the clinical data of 150 infants diagnosed with severe pneumonia and treated with HFNC therapy at our hospital from January 2021 to December 2021. These patients were divided into two groups based on their treatment outcomes: the HFNC success group (n = 112) and the HFNC failure group (n = 38).

Comparative Analysis of High-Flow Nasal Cannula Oxygen Therapy and Invasive Mechanical Ventilation in the Management of Severe Pneumonia: A Retrospective Study.

Background: Severe pneumonia continues to be a prominent cause of hospitalization and global mortality. There is ongoing debate regarding the effectiveness of different oxygen therapy modalities, particularly high-flow nasal cannula (HFNC) oxygen therapy and invasive mechanical ventilation (IMV), in the treatment of severe pneumonia.

Objective: This study investigated the risk factors associated with mechanical ventilation in pediatric patients with severe pneumonia.
