Abstract:
When a DC voltage is applied across a zirconia ceramic layer, an electrical field is established to drive oxygen species through the layer. Taking advantage of this electrochemical phenomenon, we have designed and developed an oxygen pump that offers continuously adjustable oxygen partial pressure from 1 bar down to 10(-24) bar in the temperature range of 650-1100 °C. Demonstrated with electrical conductivity measurements on Fe-doped SrTiO3, these excellent capabilities of the oxygen pump are valuable for investigations on the defect chemistry of electroceramics.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Oxygen Delivering System I: Nasal Cannula and Face Mask
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
