After the COVID-19, you may encounter many books and reference materials about the details and information of different types of oxygen masks.
During the epidemic, many severe patients need to take oxygen and deliver it to their bodies to maintain their lives, but without the help of oxygen
masks, they cannot enter.
There are 5 main types of Oxygen masks being mainly used, they are:
Simple mask
It is a basic disposable mask, made of clear plastic, to provide oxygen therapy for patients who are experiencing conditions such as chest pain (possible heart attacks), dizziness, and minor hemorrhages.
Oxygen delivery capacity 40% – 60%
Non-rebreather oxygen mask
Non-rebreather masks are often used to treat injured scuba divers. The patient does not 'rebreathe' his exhaled breath.
Non-rebreather oxygen mask delivers 10-15L of oxygen/minute and is only recommended when the patient’s saturation level is 89% and below.
Non-rebreather masks feature an attached reservoir bag and three non return valves. The bag fills with oxygen between breaths. Two of the non return valves on the side of the mask keep air from entering the mask when the patient breathes in, otherwise this would dilute the oxygen concentration. The third non return valve is located at the top of the reservoir bag to keep exhaled air from entering the bag which normally contains 100% oxygen.
Oxygen delivery capacity 60% – 95%.
