The development of apparatus for intermittent negative pressure respiration. (2) 1919-1976, with special reference to the development and uses of cuirass respirators.
This paper and the one that preceded it1 have traced the development of the design and use of negative pressure ventilators from their origins in the early nineteenth century to the present day. Their maximum use was in the nineteen-forties and the early fifties after which they were quite rapidly replaced in the treatment of acute respiratory disease by intermittent positive pressure ventilators-the turning point being the severe poliomyelitis epidemic in Copenhagen in 1952. Negative pressure ventilators, particularly cuirass ventilators, still have a place in the treatment of chronic respiratory disease.

The development of appartus for intermittent negative pressure respiration.
The history of tank and cuirass respirators from the first known use of the intermittent negative pressure principle in 1832 to 1918, on the threshold of its extensive use in the treatment of respiratory paralysis, has been related. A second article will consider the period 1918 to the present day and suggest that negative pressure apparatus-particularly the cuirass respirator-still has its uses.

Historical ArticleThe Geoffrey Kaye museum collection of portable ether inhalers.
A collection of twenty nine portable "hold in hand" ether inhalers is housed in the Geoffrey Kaye Museum. These inhalers are briefly described together with some historical notes.

Pulmonary mechanics and oxygenation were measured in 24 consecutive patients with posttraumatic flail chest requiring continuous mechanical ventilation. The mean duration of mechanical ventilation was fourteen days. Mortality was 38% for all patients, 29% if deaths from head injury are excluded. ⋯ Vital capacity and maximal inspiratory force measurements were useful in assessing chest wall stabilization. Total lung compliance correlated negatively with fatal outcome from respiratory failure. The alveolar-arterial oxygen gradient was not useful in assessing chest wall stabilization.
