Simple Oxygen Mask

Simple oxygen Mask is Medical devise used to deliver oxygen to patients who need oxygen.

What is Simple Oxygen Mask ?

This oxygen Mask is made of plastic. Mask covers the Nose and mouth to deliver the oxygen and it is connected to an oxygen source through tubing. It is a disposable item.

How much oxygen Can deliver through the Simple Oxygen ?

• 6-10 liters per minute (L/min), 
• Flow rate should not be less than 5 L/min to prevent carbon dioxide rebreathin.

O2 Concentration ( Fio2 ) :

• Delivers about 25% - 60% oxygen concentration
• The Atomspheric air contain 21% oxygen. Through oxygen flowmeter we can deliver the 4% of oxygen for each 1 liter.

(Example : Atomspheric air + liters O2 )

         21% + 4%(1liter of O2) = 25%

1=25%, 2=29%, 3=33%, 4=37%, 5=41%, 6=45%)   

When Simple oxygen Mask to be used ?        

• If oxygen saturation level decrease less than 90
• Shortness of breath
• Mild to Moderate hypoxia
• Emergency Conditions
• Respiratory infections
• Post-operative patients     

Parts of Simple Oxygen Mask ?

• Plastic face mask ( covers nose and mouth )
• Elastic head strap
• oxygen inlet port
• oxygne tubing
• Side exhalation holes for co2 escape

What are the Nursing Responsibilities during Simple oxygen Mask ?   

• Always confirm with physician orders for oxygen flow rates
• Confirm the flow is minimum 5 L/min 
• Continuous check the oxygen saturation levels
• Monitor the skin irritation around Nose and ears
• Check properly mask fit with out lekage         

What is Administration Guidelines ?

• A minimum of 6 LPM is required for all masks to flush expired carbondioxide and prevent rebreathing of CO2

• Do not use humid fier and fir firmly.

• Use for severe asthma. Pneumonia, trauma, or severe sepsis.

Advantages :

• Delivers oxygen concentrations upto 60%
• Deliver Most oxygen than nasal cannula
• Mostly used Emergency Department
• Convienient to use.

Disadvantages :

• Thight seal is required for higher oxygen concentrations hot and confi impractical long term.
• Unable to eat when using simple oxygen mask
• it make discomfort for long term use

Difference or Comparison Between Simple oxygen mask and other Mask 

• Nasal Cannula : It delivery 1-6 liter per minute and it is more comfortable.
• Non-Rebreather Mask : High level of oxygen can deliver 90-100%.
• Venturi Mask : Precise oxygen concentraion control
