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 …

2023年2月28日 · Air-entrainment (‘Venturi’) masks can consume large quantities of oxygen relative to FiO2 delivery. They are designed to be used when precise control of FiO2 is needed (e.g. patients with dependence on hypoxemic ventilatory drive as is hypothesized as theoretically needed for some COPD patients).

2017年7月27日 · A Venturi mask -- also known as an air-entrainment mask -- is a medical oxygen delivery mask that utilizes a flow meter to deliver a precise amount of oxygen. Venturi masks are indicated for use in those individuals experiencing chronic or acute respiratory distress, or when an arterial blood gas result indicates a need.

2023年7月18日 · An air-entrainment (also known as venturi) mask can provide pre-set oxygen to the patient using jet mixing. As the percent of inspired oxygen increases using such a mask, the air-to-oxygen ratio decreases, causing the maximum concentration of oxygen provided by an air-entrainment mask to be around 40%.

With the Venturi mask system, the oxygen inlet connects to a specific color-coded entrainment device at the base of the mask that provides a set fraction of inspired oxygen (FIo2) at a set oxygen intake rate.

2024年11月8日 · Air entrainment masks are devices used in oxygen therapy to deliver oxygen along with ambient air, regulating oxygen concentration based on the Venturi effect. They consist of a reservoir bag, flowmeter, and venturi valve, allowing for precise oxygen flow adjustment.

Air-entrainment (‘Venturi’) masks can consume vast quantities of oxygen. They are designed to be used when precise control of FiO2 is needed (e.g. patients with dependence on hypoxic ventilatory drive like some COPD patients).

Air entrainment mask Venturi is used for dosed patient oxygen therapy. The mask is designed taking into account the smallest anatomical features of a person. The edges of the mask are rounded and atraumatic due to the metal nose clip. The mask is securely fixed on the patient.

a type of disposable face mask used to deliver a controlled oxygen concentration to a patient. (See also oxygen therapy.) The flow of 100 per cent oxygen through the mask draws in a controlled amount of room air (21 per cent oxygen). Commonly available masks deliver 24, 28, 31, 35, or 40 per cent oxygen.

Adult MULTI-VENT® Venturi System Air Entrainment Mask is a safe, simple method of delivery for variable concentrations of oxygen.
