Abstract:
Gas embolism at the end of infusion is a well known hazard, that should have disappeared with the use of flexible bags. However, some cases have been reported after pressure infusion. This experimental study evaluates the risk for gas embolism with Ecoflac type flexible bags. These bags are safe under normal pressure infusion conditions with a pneumatic sleeve, because of their texture and pliability; indeed, only minimal air volumes could be expelled, without any risk even in children. However, to be on the safe side, the manufacturer recommends to expel any residual air before pressure administration. This recommendation applies to any bag containing residual air, and since many people are not aware of this, it is rarely put into practice.

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,...
