An oxygen mask provides a method to transfer breathing oxygen gas from a storage tank to the lungs. It’s a device worn over the nose and mouth through which is supplied from a storage tank.
What is an oxygen mask used for?
Nasal cannulas and face masks are used
to deliver oxygen to people who don’t otherwise get enough of it. They are commonly used to provide relief to people with respiratory disorders. A nasal cannula consists of a flexible tube that is placed under the nose. The tube includes two prongs that go inside the nostrils.
Some patients may prefer using a face mask instead of a cannula, as face masks offer several distinct advantages. Most notably, face masks can provide a consistent flow of oxygen and generally have a higher recommended flow rate than standard nasal cannulas, with flow rates averaging between 6 and 10 litres per minute.
