High-flow oxygen therapy is non-invasive respiratory support that delivers warmed, humidified, oxygen-enriched air to patients. It is typically used for spontaneously breathing patients who require oxygen at higher flow rates. High-flow oxygen therapy can provide respiratory support for patients with acute hypoxemic respiratory failure and can also prevent subsequent intubation. It leads to improvements in oxygenation1, respiratory rate2, dyspnea3 and patient comfort4 and helps patients recover faster following extubation1,2. This translates to improved outcomes and shorter ICU stays4. This type of o2 therapy is also economical, as it does not necessarily require a ventilator, and can be used across different hospital departments.
“As in most intensive care units, we are always interested in weaning our patients as soon as possible and have had a policy of weaning from invasive ventilation to non-invasive and then on to high-flow oxygen therapy for some patients.”
