In most circumstances, a nasal route for the delivery of pulmonary aerosol medications is rarely considered; however, in specific instances, this route may be quite useful. Consider, for example, the delivery of aerosol treatments during humidified high-flow nasal cannula use in pediatric critical care, or continuous aerosol delivery via cannula for medications with short durations of action. T...

Background: Heated humidified high-flow nasal cannula (HHHFNC) is gaining popularity in the management of respiratory distress in preterm neonates. However, it is not known whether it takes precedence over the gold standard nasal continuous positive airway pressure (NCPAP) in this age group as a primary mode of non-invasive ventilation (NIV). There is limited evidence ...

The purpose of respiratory support is to maintain adequate ventilation and oxygenation. Consequently, ensuring adequate alveolar ventilation is essential for expelling carbon dioxide produced in the human body. Currently, during invasive or noninvasive ventilatory support, minute ventilation is manipulated to ensure adequate alveolar ventilation. For patients with COPD exacerbations, noninvasiv...

Background Early initiation of appropriate noninvasive respiratory support is utmost important intervention to avoid mechanical ventilation in severe bronchiolitis. Aim This study aims to compare noninvasive continuous positive airway pressure (nCPAP) and hot humidified high-flow nasal cannulae (HHHFNC) as modes of respiratory support in infants with severe bronchiolitis. Methods Prospectiv...

Acute respiratory failure represents one of the most common causes of intensive care unit admission and oxygen therapy remains the first-line therapy in the management of these patients. In recent years, high-flow oxygen via nasal cannula has been described as a useful alternative to conventional oxygen therapy in patients with acute respiratory failure. High-flow oxygen via nasal cannula rapid...
