Oxygen masks involve the continuous deliverance of oxygen into the lungs.
- Used when patient requires more oxygen than is readily available from the environment;
- Conditions that may require the use of an oxygen mask include cystic fibrosis and COPD;
- These masks are normally composed of PVC.
Nebulizer masks dispense liquid medication as well as oxygen.
- Oxygen in aerosol droplet form, to facilitate delivery;
- Used on patients that are affected with conditions that disrupt regular breathing, for example bronchiectasis.
Venturi masks deliver a pre-calculated concentration of oxygen into the trachea.
- Primarily used in control oxygen therapy;
- 100% oxygen is fed through the mask which draws in a measured amount of air.
- Variety of types, each one catering to the different needs of the patient, the patients illness(s) and the situation;
- Relatively inexpensive;
- Transparent plastic cover to ease claustrophobic patients and provide the medical examiner with the ability to assess the patients reaction to the treatment;
- Provides oxygen-deprived patients with oxygen to increase depleted levels;
- If the supply of oxygen is contained within a bag, the patient is able to breathe more deeply without wasting the oxygen or medication;
- PVC, the primary material that oxygen masks are made from, is readily available and inexpensive. Also disposable;
- Oxygen masks are water resistant and sturdy.
In the regular oxygen mask, the oxygen supply is attached through tubing, or contained in a bag which is attached to the mask itself. Oxygen is then transferred from the source of storage into the lungs. The patient’s oxygen levels should begin to regain normal levels.
For nebulizer masks, liquid medication in conjunction with oxygen is administered to the patient. Oxygen is delivered in aerosol droplet form, to expedite delivery. The oxygen and medication is inhaled through the mouthpiece or mask. A standard dose of medicine will take approximately 7 minutes to be entirely inhaled.
In Venturi masks, a set concentration of oxygen is delivered into the trachea. This is achieved by pumping 100% oxygen through the mask, drawing in a controlled volume of air. Venturi masks can deliver up to 40% of oxygen.
Correct positioning of the oxygen mask must be ensured, as masks that are not positioned correctly may compromise their ability to deliver oxygen to a patient who is in a critical condition. Correct technique is essential to ensure the patients safety.
The correct type of oxygen mask must be used depending on the patient, their condition or disease and the situation. Using the incorrect mask may harm or even kill the patient.
It is imperative that the oxygen mask is not used if the packaging or seal is compromised. Evidence of this may suggest tampering or contamination. If one should come across masks inside comprised packaging, the correct course of action is to dispose of it quickly and safely.
- Must prepare the mask for use in a clean, sterile environment, absent of bodily fluids or other sources of contamination;
- Promptly and safely dispose of any masks that have touched a potentially contaminated surface;
- Correct material must be selected according to procedure – depending on the patient and their condition, a specific type of oxygen mask is required;
- Ensure mask is securely and correctly positioned. Poorly fitted masks may compromise their ability to deliver oxygen.
Oxygen masks are manufactured using primary PVC as the main material. Transparent plastic is the material of choice for the tubing and some other parts of the mask.
