He was also the inventor of the Venturi mask.

Venturi masks are better sources of controlled oxygen than nasal prongs.

Venturi masks are considered high-flow oxygen therapy devices.

This is because venturi masks are able to provide total inspiratory flow at a specified FO to patients therapy.

This is closely related to the more controlled air-entrainment masks, also known as Venturi masks, which can accurately deliver a predetermined oxygen concentration to the trachea up to 40%.
