Ultrasonic wave nebulizers were invented in 1965 [16] as a new type of portable nebulizer. The technology inside an ultrasonic wave nebulizer is to have an electronic oscillator generate a high frequency ultrasonic wave, which causes the mechanical vibration of a piezoelectric element.
1771: Carl Scheele (1742–1786) makes "fire air" (oxygen) by heating magnesium oxide.His findings are published in June 1774. 1774: Joseph Priestley (1733–1804), credited with the discovery of oxygen, publishes his work on "dephlogisticated air" oxygen 3 months after a report by Carl Scheele.
While the 4 other competing type of inhalers are relatively new inventions. The first "gas inhaler" (or breathing apparatus) was invented and designed by James Watt in 1793. The first nebulizer was invented and designed by Sales-Girons in 1858. The first dry powder inhaler was invented by Newton in 1864.

The timeline of historic inventions is a chronological list of particularly significant technological inventions and their inventors, where known. [ a ] The dates in this article make frequent use of the units mya and kya , which refer to millions and thousands of years ago, respectively.
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.
In 1988, the company went public under the stock ticker symbol RESP. In 1992, Respironics received a patent for bi-level technology. This technology was originally intended as an improvement on CPAP, however, its use has expanded into the treatment of other breathing disorders such as chronic obstructive pulmonary disease (COPD).
