What is the difference between a simple face mask and a non-rebreather mask?
It’s used for people who can breathe on their own but may have low blood oxygen levels. A simple face mask doesn’t deliver as high of an oxygen concentration as a non-rebreather mask but is safer in the case of a blockage. A rebreather mask is a misnomer and doesn’t exist in the context of oxygen therapy.
Is simple mask high flow?
Nasal cannula and simple face masks are described as low flow delivery systems. Unlike the non-rebreather and partial rebreather masks, the simple face mask lacks a reservoir bag.
When would you use a simple mask?
Simple face masks are used and are effective when patients require a high percentage of oxygen. They can be used for hours or several days, but should be used in conjunction with a humidifier if used for more than 12 h and/or the patient has a dry or productive cough (Perry et al. 2016).
Are droplets aerosols?
By comparison to droplets, aerosolized particles are infinitesimal. Size alone is not the only important distinction: Droplets fall to earth quickly, but aerosols can travel on air currents potentially for hours.
How many liters of oxygen do you need for a simple mask?
The recommended flow rate range of the simple mask is 6 to 10 liters per minute and the oxygen percentages vary from 40% to 60%. A minimum flow of 6 liters is necessary to help “flush” out the patients exhaled carbon dioxide which passes through the small holes on the sides of the mask previously mentioned.
Is a Venturi mask a simple mask?
Fixed performance devices provide a more consistent and predictable Fio2 to the patient. The most common such device is the venturi oxygen mask (Table 6–5). Venturi masks consist of a clear plastic mask, similar to the simple adult face mask detailed in the prior section, and a plastic venturi device (Figure 6–6).
Can you use humidity with a simple mask?
A simple mask should be administered for only a few hours because of the low humidity delivered and the drying effects of the oxygen gas. This device is best used for short-term emergencies, operative procedures, or for those patients where a nasal cannula is not appropriate.
How many liters of oxygen do you need for a simple face mask?
What is the disadvantage of using aerosol?
There are also disadvantages to aerosol drug therapy. One of the most important disadvantages is that specific inhalation techniques are necessary for the proper use of each of the available types of inhaler device. A less than optimal technique can result in decreased drug delivery and potentially reduced efficacy.
What are the different types of face masks?
1 Simple mask. Face mask – The face mask covers both nose and mouth. There are no valves to limit the flow of air. 2 Non-rebreather mask (Hudson mask) Face mask with 2 one-way valves- The face mask covers both nose and mouth. 3 Partial rebreather mask. Face mask with 1 two-way valve- This is similar to a non-rebreather mask.
How much oxygen can a simple face mask deliver?
A simple mask can deliver oxygen at a concentration of about 28-50% [10] at a flow rate of 5- 10 LPM (Litres per minute). Face mask with 2 one-way valves- The face mask covers both nose and mouth. A one-way valve is present between the reservoir bag and the face mask.
What is the difference between face masks and non-rebreather masks?
Face mask with 1 two-way valve- This is similar to a non-rebreather mask. The difference is in the valve that connects between the reservoir bag and the face mask.
What are the disadvantages of the O2O oxygen mask?
Oxygen flows into the reservoir at 8-15 liters, washing the patient with a high concentration of oxygen. Its major drawback is that the mask must be tightly sealed on the face, which is uncomfortable and drying. There is also a risk of CO 2 retention if the mask reservoir bag is allowed to collapse on inspiration.
