Understanding the Different Types of Oxygen Masks and Their Uses

Posted by Tentabs Tech Solutions Pvt Ltd on

Many respiratory problems require oxygen therapy. The effectiveness of oxygen masks depends on ensuring patients get the best possible amount of oxygen for their particular needs. This blog will cover the different kinds of oxygen masks, their uses, and how to use an oxygen mask correctly. Selecting the ideal oxygen mask for therapy and patient care requires knowledge of the different kinds and uses of oxygen masks.

What are Oxygen Masks?

Equipment called oxygen masks transports oxygen from a storage tank to the lungs. They cover the lips and nose and are tied around the head with an elastic band. In hospitals, at home, and during emergencies, oxygen masks supplement oxygen for those who have trouble breathing.

Types of Oxygen Masks

Oxygen masks come in various forms, each intended to provide oxygen at a distinct concentration and flow rate. The mask is selected based on the patient's medical state, the needed oxygen concentration, and the surroundings. This page will discuss the most often used oxygen mask types and their uses.

Nasal cannula

  • Two prong-equipped, lightweight tubes called nasal cannulas are inserted into the nostrils.
  • The target market for this kind of oxygen mask is those who need low-flow oxygen treatment. Patients requiring long-term oxygen therapy at home or those with chronic respiratory conditions like COPD (Chronic Obstructive Pulmonary Disease) often utilise it.
  • Flow Rate: Delivers oxygen between 1-6 litres per minute (LPM) at a concentration between 24 and 40%.
  • Benefits of oxygen mask: They are less evident than other types of masks, comfortable, and allow for eating and conversing.

The Basic Oxygen Mask

  • An elastic band secures this basic oxygen mask, which covers the nose and mouth.
  • Uses: It is perfect for those needing a higher oxygen concentration than a nasal cannula can deliver. Hospitals commonly employ it to give patients short-term oxygen therapy.
  • Gives oxygen at a 40–60% concentration at a flow rate of 6–10 LPM.
  • Benefits of oxygen mask: Higher oxygen concentration and ease of usage.

Venturi Mask

  • Also known as an air-entrainment mask, the Venturi mask features a special valve that precisely combines oxygen with surrounding air.
  • Uses: It is ideal for those needing constant and exact oxygen concentration. For those with COPD, it is often used to prevent decreasing respiratory drive.
  • Flow Rate: Depending on the adapter, it delivers oxygen between 4 and 12 LPM at a 24-60% concentration.
  • Benefits of oxygen mask: Provides precise oxygen delivery; suitable for patients with different breathing rates.

Non-Rebreather Mask

  • The reservoir bag of a non-rebreather mask stores oxygen. The one-way valves on the mask keep air exhaled from getting into the reservoir bag.
  • Uses: It is used for patients who need a high oxygen concentration, such as those in critical condition or experiencing acute hypoxia.
  • Provides oxygen at a concentration of 60–100% with a flow rate of 10-15 LPM.
  • Benefits of oxygen mask: Short of intubation, Offers the highest oxygen concentration that can be achieved with a mask.

Partially Rebreather Mask

  • Description: Lacking one-way valves, it resembles a non-rebreather mask. A portion of the exhaled air combines with the reservoir bag's oxygen.
  • Uses: In patients who need high oxygen concentrations.
  • Flow Rate: The flow rate is 8–15 LPM of oxygen at a 50–70% concentration.
  • Benefits of oxygen mask: Maintains high concentrations and enables oxygen conservation.

Face Tent

  • A loose-fitting face tent mask shields the lips and nose from direct contact.
  • Uses: Perfect for patients who, including those with face injuries or after surgery, feel claustrophobic or cannot wear a tight-fitting mask.
  • Flow Rate: Provides oxygen at a concentration of 40–60% and 10-15 LPM flow rate.
  • Benefits of oxygen mask: Its advantages are more comfortable for prolonged use and less restrictive. 

How to Use an Oxygen Mask?

Treatment success depends on knowing how to use an oxygen mask effectively. Following are some broad procedures:

  1. Verify that the oxygen source—a tank or concentrator—is operating as it should and that the flow rate is adjusted per the doctor's directions.
  2. Plug the mask into an oxygen supply. Verify the reservoir bag is completely inflated before putting the mask on the patient.
  3. Place the mask over the patient's mouth and nose. Adjust the elastic strap to fit it snugly but comfortably.
  4. Observe the patient. Seek clues of pain or annoyance. Assure the patient has easy breathing and that the mask stays in place.
  5. As the manufacturer advises, clean the mask frequently to prevent infections and maintain its effectiveness.

Selecting the Optimal Therapy Oxygen Mask

When selecting an oxygen mask, consider the patient's comfort, necessary oxygen concentration, and unique medical supplies.

  • Consult with Healthcare Professionals: Always get advice from a medical professional to ascertain the best kind and use of oxygen mask for a particular problem.
  • Take the Environment into Consideration: A basic mask or nasal cannula can be more suitable for home use. A non-rebreather mask may be needed in an emergency or for severe hypoxia.
  • Evaluate Comfort and Fit: Make sure the mask fits comfortably to prevent leaks and soreness, which can lessen the therapy's efficacy.

Effective oxygen therapy requires knowledge of oxygen mask types and uses. Every type of oxygen mask has a different function, ranging from non-rebreather masks for high concentrations to nasal cannulas for minimal flow requirements. Ensuring patients with respiratory problems get the oxygen levels needed for their health and well-being and knowing oxygen mask types and uses appropriately can greatly enhance their therapy.

Better patient outcomes and efficient therapy depend on your knowledge of the types and uses of oxygen masks, whether you are a patient, carer, or healthcare professional. Always consult with a medical professional for the appropriate oxygen mask based on your unique requirements and situation.
