Question

Quizplus · Accepted Answer

Face masks with reservoirs (partial rebreathing and non-rebreathing reservoir masks)provide oxygen concentration of 60% or higher.The addition of the reservoir increases the amount of oxygen available to the patient during inspiration and allows for the delivery of concentrations of 35% to 60% (partial rebreather)or 60% to 80% (non-rebreather),depending on the flowmeter setting,the fit of the mask,and the patient's respiratory pattern.The high-flow nasal cannula,not the traditional low-flow models,can provide higher flows.The simple face mask can deliver flows up to 60%.The Venturi mask allows better regulation of oxygen concentration and generally does not deliver more than 60% oxygen.
