The tussometer: accuracy and reproducibility.
Tussometry is a new non-invasive technique for objectively assessing laryngeal function by analysis of the airflow waveform produced by a maximum effort voluntary cough manoeuvre. We describe the technique and present the calibration data. The tussometer has been calibrated for flows of up to 1100 litre min-1 using a flowmeter with a quoted accuracy of +/- 1.75%. The variables measured (cough peak flow rate (CPFR) and peak velocity time (PVT)) were found to be reproducible; the within-subject variability for CPFR was found to be 23.9% and for PVT 9%. There was no inter-observer variation. We found that the size of the mask used did not influence the readings obtained, providing an adequate seal was achieved.

Theory as a guide to practice: staff nurses choose Parse's theory.
This paper describes the changes that occurred in staff nurses' thoughts and actions when Parse's theory was used as a guide for practice on an acute care medical unit. As participants in an eight month evaluation project of Parse's theory, nurses struggled to change in a process of growth which led to new approaches in practice. Ways of thinking about patients and practice before and after Parse's theory clarify how this approach is different from the traditional biomedical model. Nurses describe how their perspective of human beings changed from viewing patients as problems to viewing patients as unique individuals. Healing nurse-person relationships led to enhanced satisfaction and morale for nurses and improved quality of care for patients. This article offers challenging ideas for all nurses interested in testing nursing theory and in particular for nurses interested in Parse's humanistic approach.
