Effect of Flow Rates of High-flow Nasal Cannula on Extubation Outcomes: A Randomized Controlled Trial.
Chest
December 2024
From the Division of Pulmonary and Critical Care Medicine, National Taiwan University Hospital, Taipei, Taiwan. Electronic address:
Background: High-flow nasal cannula (HFNC) has emerged as a promising intervention for post-extubation oxygen therapy, with the potential to reduce the need for reintubation. However, it remains unclear whether using a higher flow setting provides better outcomes than the commonly used flow rate of 30-50 L/min.
Research Question: Does setting the flow rate of HFNC at 60 L/min versus 40 L/min for post-extubation care result in different extubation outcomes?
Study Design And Methods: This randomized controlled trial assigned intubated patients to receive HFNC at either a 60 L/min or 40 L/min flow rate following extubation.
Portable UV-C device to treat high flow of infectious aerosols generated during clinical respiratory care.

Respiratory interventions including noninvasive ventilation, continuous positive airway pressure and high-flow nasal oxygen generated infectious aerosols may increase risk of airborne disease (SARS-CoV-2, influenza virus) transmission to healthcare workers. We developed and tested a prototype portable UV-C device to sterilize high flows of viral-contaminated air from a simulated patient source at airflow rates of up to 100 l/m. Our device consisted of a central quartz tube surrounded 6 high-output UV-C lamps, within a larger cylinder allowing recirculation past the UV-C lamps a second time before exiting the device.

The aim was to identify predictors for early identification of HFNC failure risk in patients with severe community-acquired (CAP) pneumonia or COVID-19. Data from adult critically ill patients admitted with CAP or COVID-19 and the need for ventilatory support were retrospectively analysed. HFNC failure was defined as the need for invasive ventilation or death before intubation.

Noncardiogenic pulmonary edema after cardiac surgery is a rare but severe complication. The etiology remains poorly understood; however, the issue may arise from multiple sources. Possible causes include a significant inflammatory response or an autoimmune process.

Objective: This study aimed to investigate the prognostic impact of completing 30 mL/kg fluid resuscitation within 1 h in elderly septic shock patients.
Methods: This was a multicenter prospective observational cohort study. We applied logistic regression to assess the impact of completing 30 mL/kg fluid resuscitation within 1 h on respiratory support escalation including new-onset mechanical ventilation, bilevel positive airway pressure (BiPAP), and high-flow nasal cannula (HFNC) as well as heart failure (HF).
