A new generation of anaesthetic ventilators. The Pneupac and Penlon A-P

A new range of ventilators which can be used during anaesthesia for infants, children and adults is described. The ventilators work on the moving-part fluid logic principle and are simple, inexpensive and robust; the patient valve can be autoclaved at standard temperatures (140 degrees C). There are facilities for providing PEEP, attachment of a scavenging system and for relief of over-pressure. The unit is 'fail-safe'. The ventilators, being constant flow generators, have a high specification and equal the performance of other machines which are five times the cost. The weight and size are such that servicing can be provided on a replacement exchange basis through the post.
