Principles of non-invasive ventilation: a critical review of practice issues
1De Montfort University, Falculty of Health and Life Sciences, School of Nursing and Midwifery, Leicester.
Abstract:
This article is the second of a two-part review on mechanical ventilation, with particular emphasis on the practice of non-invasive ventilation. Part 1 explored the principles underpinning artificial ventilation. It went on to explain the difference between positive and negative pressure ventilation, and differentiated between invasive and non-invasive modes of ventilation. Finally, it examined the various operational features, flexibility in use and limitations that artificial ventilation therapy presents. In this second part, the article focuses on the practice of non-invasive ventilation. It addresses the indications and contraindications, patient selection, initiation, maintenance, weaning processes, and problems specifically associated with non-invasive ventilation. Practical remedies are explored and potential areas for research are indicated.

Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
