Disposable Venturi Oxygen Mask With Oxygen Tube (2 Color), Venturi Oxygen Mask Kit
A Disposable Venturi Oxygen Mask with Oxygen Tube is a medical device designed for the delivery of controlled and adjustable oxygen concentrations to patients with respiratory conditions. This type of mask utilizes the Venturi principle to mix a specific amount of room air with oxygen, providing a precise fraction of inspired oxygen (FiO2). The inclusion of two colors in the mask likely indicates the availability of two different oxygen concentration settings.
1. Venturi System: The mask operates on the Venturi principle, incorporating multiple color-coded vents or orifices that allow healthcare providers to select different oxygen concentrations based on the patient's needs.
2. 2-Color Design: The presence of two colors likely indicates two different oxygen concentration options. Each color corresponds to a specific FiO2 level, providing flexibility in adjusting the oxygen delivery based on the patient's respiratory requirements.
3. Disposable Design: The mask is intended for single-use, and its disposable nature reduces the risk of cross-contamination between patients. This is particularly important for infection control in medical settings.
4. Oxygen Tube: The mask is connected to an oxygen source via an included oxygen tube. The tube allows for the delivery of oxygen from a centralized source or an oxygen cylinder.
5. Elastic Head Strap: An elastic head strap is typically included to secure the mask comfortably on the patient's face.
6. Transparent Material: The mask is often made from transparent materials, allowing healthcare providers to visually assess the patient's skin color and monitor for signs of respiratory distress.

Is Venturi mask low or high-flow?
Venturi masks are low-flow masks that use the Bernoulli principle to entrain room air when pure oxygen is delivered through a small orifice, resulting in a large total flow at predictable Fio2.
A Venturi mask is considered a high-flow oxygen delivery system. High-flow oxygen delivery systems provide a relatively high and precisely controlled flow of oxygen to the patient. The Venturi mask is designed to deliver a specific and accurate fraction of inspired oxygen (FiO2) by using a system of vents or orifices of different sizes to mix oxygen with room air.
Can Venturi mask deliver 100% oxygen?
No, a Venturi mask is not designed to deliver 100% oxygen. The design of the Venturi mask includes a system of vents or orifices of different sizes that mix a controlled amount of room air with the oxygen flow. This mechanism allows for the precise delivery of a specific fraction of inspired oxygen (FiO2) that corresponds to the chosen vent size.
The maximum FiO2 that can be achieved with a Venturi mask is typically around 60-70%. The reason for this limitation is that the Venturi mask relies on entrainment to mix room air with the oxygen flow, and it cannot deliver 100% oxygen because room air (which contains about 21% oxygen) is always entrained.
If a higher concentration of oxygen, closer to 100%, is required, other oxygen delivery systems may be used, such as a non-rebreather mask or a high-flow nasal cannula (HFNC). Non-rebreather masks, for example, can provide higher concentrations of oxygen because they have a one-way valve system that prevents the patient from inhaling room air and allows for the delivery of a higher concentration of oxygen from a reservoir bag.
The choice of the appropriate oxygen delivery device depends on the patient's condition, oxygenation requirements, and the desired FiO2. Healthcare professionals assess these factors to determine the most suitable oxygen therapy for each individual case.
Venturi system masks can deliver between 24% and 60% oxygen, depending on the connector used.
