Miniature Ventilators with Interrupted Non-Rebreathing Circle Systems and Other Anaesthetic Circuits

A brief description of the mechanical principles involved in three modern miniature ventilators is presented.

Anaesthetic circuits as recommended in the past are illustrated and their shortcomings expressed in the light of our experience.

An interrupted non-rebreathing circle system adaptation is described.

Arterial Pacoco2 observations are presented and interpreted.

Dangerous pitfalls to be avoided in setting up circuits are described.

Explanations for clogged magnetic valves in the inspiratory mode are presented and prophylactic and corrective measures recommended to avoid overinflation of the lungs.

The economic aspects of ventilator miniaturization are discussed with regard to initial low cost and total anaesthetic mixture output.

A semi-closed partial-rebreathing system is described but not necessarily recommended because "overloading" with intermediate pneumatic accessories appears to interfere with the fidelity of operation of miniature ventilators.
