1. Product IntroductionThe 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. The mask was invented by Moran Campbell at McMaster University Medical School as a replacement for intermittent oxygen treatment, a practice he described as "bringing a drowning man to the surface- occasionally".Venturi masks are considered high-flow oxygen therapy devices. This is because venturi masks are able to provide total inspiratory flow at a specified FiO2 to the patient therapy. The kits usually include multiple jets, which are usually color-coded, in order to set the desired FiO2.2.
