Hosted by the National Asthma Council of Australia, this online "handbook was written as a guide for those involved in the performance and interpretation of spirometry in clinical practice, i.e. medical practitioners and assisting nursing staff, and as an introduction to the topic for scientists and technicians." Initially published in 1995 by Drs. Rob Pierce and David P. Johns, the Spirometry Handbook was revised in July 2004. The brief sections include Measurement of Ventilatory Function; Measurement Devices; Infection Control Measures; and Predicted Normal Values. The publication also offers a number of references, and suggestions for further reading. Handbook users may print individual pages and link to a couple brief video clips as well.
