An overview of ventilator observations.

Nursing staff new to intensive care can often be apprehensive when observing, recording and interpreting ventilator observations. This review of ventilation and the necessary observations involved offers a description of the observations performed, with a problem-solving approach to cause, rationale and possible action that may be required. Calculations related to spontaneous and mechanical respiratory function are discussed, with recommendations for individual requirements. Explanation of available settings, demonstrating the functions and delivery methods of different ventilators is included, and a discussion on alarm settings and rationale. For the purpose of assessing the ventilatory support in use there is a guide to interpretation of arterial blood gases with suggestions and rationale for necessary changes of parameters.
