What every intensivist should know about using high-flow nasal oxygen for critically ill patients
The most conventional forms of oxygen delivery rely on facemasks, a nasal cannula or nasal prongs. However, the use of these methods is limited by certain drawbacks, including the need for a flow of oxygen higher than 15L/min in case of severe hypoxemia or the dilution of administered oxygen by entrained room air in cases of high inspiratory flow. An alternative to conventional oxygen therapy h...
متن کاملEffect of high-flow nasal cannula on thoraco-abdominal synchrony in adult critically ill patients.
BACKGROUND High-flow nasal cannula (HFNC) creates positive oropharyngeal airway pressure and improves oxygenation. It remains unclear, however, whether HFNC improves thoraco-abdominal synchrony in patients with mild to moderate respiratory failure. Using respiratory inductive plethysmography, we investigated the effects of HFNC on thoraco-abdominal synchrony. METHODS We studied 40 adult subje...
متن کاملHeated Humidified High-Flow Nasal Oxygen in Adults: Mechanisms of Action and Clinical Implications.
Traditionally, nasal oxygen therapy has been delivered at low flows through nasal cannulae. In recent years, nasal cannulae designed to administer heated and humidified air/oxygen mixtures at high flows (up to 60 L/min) have been gaining popularity. These high-flow nasal cannula (HFNC) systems enhance patient comfort and tolerance compared with traditional high-flow oxygenation systems, such as...
متن کاملHigh flow nasal cannula improves lung aeration and enhances CO2 removal in hypoxemic critically ill patients
Methods We performed a prospective randomized cross-over study on hypoxemic (PaO2/FiO2 ≤300 mmHg) non-intubated patients admitted to Intensive Care Unit of San Gerardo Hospital. We delivered the same air/oxygen mix by HFNC (40 L/min) and facial mask for 20 minutes by random order. Continuous recordings of lung aeration and minute ventilation by Electrical Impedance Tomography (EIT) and of inspi...
متن کاملFor critically ill patients, is high-flow nasal cannula oxygen delivery a suitable alternative to mechanical ventilation?
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...
