Which term describes the technique of delivering high flow oxygen?

• A. High flow oxygen
• B. Low flow oxygen
• C. Nebulization
• D. Mechanical ventilation

Answer: (A)

High flow oxygen therapy delivers oxygen at rates that meet or exceed a patient’s inspiratory demand, usually with humidified, heated gas and a high FiO2. This approach lets you provide very precise oxygen concentrations (often near 100%) and helps wash out dead space in the upper airway, which improves oxygen uptake, especially in patients with significant respiratory effort. In EMS practice, this is typically done with devices like a high-flow nasal cannula, which can push large volumes of oxygen quickly to support hypoxemic patients. Low flow oxygen uses standard systems (like a simple nasal cannula or basic face mask) at lower rates, which may not meet the patient’s breathing needs and result in fluctuating oxygen concentration. Nebulization is about turning liquid medications into an inhalable aerosol and is not a method for delivering oxygen itself. Mechanical ventilation provides breaths via a ventilator, offering full ventilatory support rather than simply delivering high-flow oxygen.
