Venturi mask - Wikipedia
The venturi mask, also known as an air-entrainment mask, is a medical device to deliver a known oxygen concentration to patients on controlled oxygen therapy. [ 1 ] [ 2 ] The mask was invented by Moran Campbell at McMaster University Medical School as a replacement for intermittent oxygen treatment.
Venturi Mask - an overview | ScienceDirect Topics
The Venturi mask is a fixed performance device that delivers a constant concentration of oxygen in spite of the patient's respiratory pattern, by providing a higher gas flow than the peak inspiratory flow rate.

2022年8月15日 · Venturi masks are designed to deliver constant FiO2 regardless of the patient’s respiratory rate and flow pattern (i.e. a fixed-performance device). They are used to deliver oxygen to patients with chronic obstructive pulmonary disease (COPD) due to the risk of type 2 respiratory failure.

Venturi masks are often used in COPD, where it is important not to over-oxygenate the patient. Note that saturations should be maintained at 94-98%, not 100%. Do not keep patients on 15L for longer than necessary as over-oxygenating for prolonged periods can be harmful.
Venturi Mask - an overview | ScienceDirect Topics
A Venturi mask is a medical device that is designed to deliver a specific oxygen concentration to a patient by using color-coded entrainment devices. It is particularly useful for patients with COPD who require controlled oxygen therapy to prevent hypercarbia.
