A resuscitator is a device using positive pressure to inflate the lungs of an unconscious person who is not breathing, in order to keep them oxygenated and alive. [citation needed] There are three basic types: a manual version (also known as a bag valve mask) consisting of a mask and a large hand-squeezed plastic bulb using ambient air, or with supplemental oxygen from a high-pressure tank.
The mask end of a SAR is generally lower-maintenance than an SCBA, but the air compressors or tanks at the other end of the hose require monitoring and maintenance. [3] [4] It is important that they deliver good air; contaminants (which may also be introduced by faulty operation of the machinery) can be dangerous. [3]

There are two major application areas for SCBA: firefighting, and industrial use in confined spaces. [20] For SCBAs used in firefighting, manufacturers typically prioritize fire resistance and weight reduction over ...
An inhaler (puffer, asthma pump or allergy spray) is a medical device used for delivering medicines into the lungs through the work of a person's breathing. This allows medicines to be delivered to and absorbed in the lungs, which provides the ability for targeted medical treatment to this specific region of the body, as well as a reduction in the side effects of oral medications.
