Abstract
The use of standard oxygen therapy has long been the first-line therapy in patients with acute respiratory failure (ARF), though this oxygenation strategy does not lead to a reduction in work of breathing and the FiO2 delivered to the patient does not usually overstep 70%. Moreover, gas provided by standard oxygen therapy tools is markedly dry and may be irritating for airways. All these disadvantages may lead to failure of the technique and subsequent need for intubation. The use of non-invasive Continuous Positive Airway Pressure (CPAP) is one of the main alternatives to standard oxygen in patients with ARF, before endotracheal intubation. However, tolerance to CPAP is sometimes poor due to a tight-fitting mask and to frequent leaks around the interface, leading to patient–ventilator asynchronies. High-flow CPAP is a more recent technique that could have many beneficial effects and overcome some of the limitations of both standard oxygen therapy and non-invasive CPAP.
