A patient with chronic obstructive pulmonary disease (COPD) requires high-oxygen supplementation with a precise oxygen concentration. The nurse should anticipate the physician ordering which of the following?

Venturi mask


•The Venturi mask is the most accurate oxygen delivery system. Patients at risk for CO2 retention, such as COPD patients, benefit from a venturi mask because the FiO2 can be controlled.

•Nasal cannula is a low-flow delivery system.

•The aerosol mask is most often used for high humidity.

•BiPAP is used when additional pressure support is needed with ventilation.
