As per the Centers for Disease Control and Prevention (CDC), in the United States, approximately 16 million people have been diagnosed with chronic obstructive pulmonary disease, abbreviated as COPD. Many of them need oxygen therapy that needs to be continuous but controlled. For this purpose, the physician chose the Venturi masks which do the job better than the standard oxygen masks owing to their design and working principle. By answering the FAQs About Venturi Masks, we will help in understanding why these masks are preferred in such treatments.
FAQs about Venturi Masks
However, despite their vast use, people often ask multiple questions regarding their use, how they differ from other masks, as well as their shelf-life and cost. Therefore, some of these FAQs about Venturi masks will be addressed in this article.
1. What is a Venturi Mask Used For?
The Venturi masks, also known as air-entrainment masks, are employed to deliver a predetermined amount of oxygen to the patients with an aim to provide controlled non-invasive ventilation.
2. Why is it Called Venturi Mask?
The Venturi masks were named after the Italian physicist Giovanni Battista Venturi to honor him as he presented the principle that an increased gas velocity causes a decrease in its pressure. Based on this principle, Moran Campbell designed these masks with the aim of replacing intermittent oxygen therapy with a controlled one.
3. What is the Working Principle of Venturi Masks?
The Venturi masks work based on the Bernoulli principle. It says that if a fluid is constricted, its velocity will increase and pressure will be lowered. By taking this principle as a base, the Venturi masks have been designed.
4. How are Venturi Masks Different from Other Oxygen Masks?
One of the most FAQs about Venturi masks is how they differ from other oxygen masks. Venturi masks provide a controlled, precise oxygen concentration to patients by utilizing the Bernoulli principle, making them ideal for conditions like COPD where consistent oxygen levels are crucial. In contrast, standard oxygen masks deliver varying oxygen concentrations, which can be less precise and less suitable for patients needing specific oxygen levels. Other masks do not use Venturi masks mechanism so they deliver altering concentrations of oxygen when used for respiratory assistance.
5. How Much Oxygen Concentration and Oxygen Flow Rate Can a Venturi Mask Give?
A Venturi mask can deliver up to 24 to 60% oxygen to the patient. These masks are color-coded for easy differentiation. The following table shows the types of Venturi masks, their flow rates, as well as the percentage of oxygen they deliver:
| Types of Venturi Masks | Flow Rate (L/min) | Percentage of Oxygen Delivered (%) |
| Blue | 2 to 4 | 24 |
| White | 4 to 6 | 28 |
| Yellow | 8 to 10 | 35 |
| Red | 10 to 12 | 40 |
| Green | 12 to 15 | 60 |
6. How Do I Know Which Venturi Mask to Use?
A suitable Venturi mask should be selected based on the flow rate and oxygen percentage which is intended to be delivered to the patient. This can be decided by a healthcare provider who will evaluate the patient’s needs and then select a mask accordingly.
7. What is the Application of Venturi Masks?
The Venturi masks are best for administering oxygen at a specified rate. These are best for patients suffering from chronic obstructive pulmonary disease (COPD) as these masks do not over-oxygenate the lungs thus minimizing the chances of unconsciousness and death.
8. What are the Advantages of Venturi Masks?
The Venturi masks have the following advantages:
● These masks provide humidified oxygen to the patients which is highly comfortable.
● With the Venturi masks, the mucous membranes do not become dry which may cause irritation to the patient.
9. What are the Disadvantages of Venturi Masks?
The Venturi masks come with the following disadvantages:
● With the use of Venturi masks, there is a higher chance of suffocation in case in case of an interrupted flow of oxygen. Therefore, it is necessary to supervise the patients who are using these masks.
● These masks may feel a bit hot and confining to some patients.
● The Venturi masks also interfere with daily activities like eating or talking.
10. Who Should Not Use Venturi Masks?
The Venturi masks are not used in patients who are suffering from facial injuries. As these masks work best when secured tightly in place, a necessary process needed for the proper working of Venturi masks, this approach cannot be adopted in patients dealing with facial trauma.
11. Are the Venturi Masks Sterile?
No, the venturi masks are non-sterile single-use products that are soft and flexible and can be adjusted based on the patient’s needs.
12. What is the Shelf Life of Venturi Masks?
The Venturi masks are good to be used up to 5 years after their manufacturing.
13. From Where Can I Buy Venturi Masks?
The Venturi masks can be bought from your nearby pharmacies. These can also be bought online from trusted websites like Health Supply 770 which offers the best products at the most affordable prices.
14. What is the Price of a Venturi Mask?
The price of a single Venturi mask is usually above $100. Although, the prices may vary based on the company you are purchasing from. The following table shows two types of Venturi masks which are available at Health Supply 770 along with their prices:
| Products | Prices (USD) |
| SunMed Percent-02-Lock Venturi Mask | 120.65 |

15. How to Store the Venturi Masks?
The Venturi masks should be stored away from direct sunlight in a cool and dry place.
