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.

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 Sarco pod (also known as Pegasos, and sometimes referred to as a "suicide pod" [1]) is a euthanasia device or machine consisting of a 3D-printed detachable capsule mounted on a stand that contains a canister of liquid nitrogen to die by suicide through inert gas asphyxiation. "Sarco" is short for "sarcophagus".
This is a new type of nebulizer which does not use induction to mix the sample and gas. Instead, pneumatic atomization is employed here, which results in the micro-mixing of fluids using a reflux cell. [5] This means that there is a turbulent mixing of the liquid and gas which results in great sensitivity and is very efficient.
The ethanol must be converted from liquid into gaseous state (vapor) or aerosol (mist), [22] in some cases using a nebulizer, a machine that agitates the liquid into an aerosol. The sale of nebulizers for inhaling ethanol was banned in some US states due to safety concerns. [23]
The Engtröm 150 artificial respirator, which delivered air straight into the lungs using an endotracheal tube placed into the windpipe, was invented by Carl-Gunnar Engström. Carl Gunnar David Engström (1 September 1912 – 9 January 1987) was a Swedish physician and innovator.
Non-invasive ventilation (NIV) is the use of breathing support administered through a face mask, nasal mask, or a helmet.Air, usually with added oxygen, is given through the mask under positive pressure; generally the amount of pressure is alternated depending on whether someone is breathing in or out.
