Comparative Study
Lung function in an Australian population: 1. Spirometric standards for non-smoking adults.
Relationships between age, height, weight and spirometry with FEV0.5, FEV1, FVC and FEV1/FVC are described for a sample of 6275 female and 6511 male non-smoking adults living in New South Wales. Prediction equations for ventilatory function tests are derived from non-smokers and compared with other standards that are available in a population sample of 31172 subjects. It is concluded that the standards described in this paper are more appropriate for use in Australian populations. Nomograms for predicting FEV1 and FVC in females and males are provided.

The brain-stem electroencephalograph (EEG)-evoked response (BSER) constitutes a reliable and objective method of testing hearing in infants, and in uncooperative, or retarded patients. The procedure is harmless and painless, and involves recording the EEG brain-stem responses to clicks presented by headphones. The patient may be sedated, or even anaesthetized, if necessary. Because of the equipment and time involved, the procedure is not recommended as a routine screening procedure, but constitutes a valuable adjunct to conventional audiological testing, especially in doubtful cases.
