Abstract:
In a follow-up to last month's "Fighting the waterborne menace" article (HEJ--March 2010), Dr. Tom Makin, directorate manager, medical microbiology, at the Royal Liverpool and Broadgreen University Hospitals Trust, and Martin Pride, new business development, at Kemper U.K. & Ireland, examine how Legionella has become a significant potential issue in hospital water systems, and discuss a novel, venturi-based engineering system co-developed by Kemper and a German university, and recently successfully trialled at a Liverpool hospital, which ensures constant water circulation, significantly reducing the risk of both biofilm, and consequently Legionella, build-up.

Bernoulli's Principle: Applications
Entrainment devices use a high fluid speed to create low pressures and, thus, entrain one fluid into another. Some examples of these devices are given below:
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,...
Mechanical Ventilation II: Invasive Ventilation
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...
Bernoulli's Equation: Problem Solving
The first step is to compute the cross-sectional areas of the pipe and the Venturi throat to analyze the pressure difference indicated by the pressure gauge. Next, the continuity equation is...
