We analyzed the value of the (n) coefficient of nasal flow in the formula of nasal resistances in order to: (1) calculate nasal flow during the course of the nasal provocation test, and (2) try to find out whether nasal flow maintains the same characteristics during the test. Our results show that values vary between 1.6589 and 1.8801, with a weighted mean of 1.7645--suggesting that the flow is of a mixed character--without significant differences during the course of the test. At the same time we carried out an analysis of the dynamics of nasal flow during nasal provocation.

Study Objectives: The prevalence of obstructive sleep apnea (OSA) increases dramatically in adolescents with overweight or obesity. The gold standard for diagnosis of OSA is in-laboratory polysomnography (PSG). However, access to PSG can be challenging, necessitating development of alternative devices.

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.

The use of new oxygen supports associated to non-invasive respiratory strategies is well-established in clinical practice, especially after its extensive application in the management of Covid-19 respiratory failure. The use of high flow nasal cannula (HFNC) in patients undergoing procedural sedation and analgesia (PSA) is dramatically increasing. Enzymatic debridement in critical burn patients is a painful treatment that requires an optimal burn pain control protocol as well as a deep sedation for the entire duration of the procedure.

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.

Aim: High flow nasal cannula (HFNC) therapy is a form of respiratory support used in children with bronchiolitis. A national guideline for the use of HFNC was published in The Netherlands in 2020. We studied the implementation and use of this guideline.
