Optimal respirator settings in assisted respiration
Medical & Biological Engineering, 1974An analysis of assisted respiration, based on a linear, first-order lung model, has been performed using rectangular, sine and ramp input pressure waveforms. The results of the analysis have been applied to predict optimal respirator settings. The criterion of a simultaneous minimisation of the average alveolar pressure and ventilatory work per minute ...

Respiration Physiology: The Control of Respiration
Respiratory Care, 1957We have outlined the chief nervous and chemical means of regulating ventilation of the lungs, and described in some detail how each works. Others beyond the scope of this presentation have been deliberately ignored-not, we think, with any detriment to the therapist's understanding of the subject, as they are relatively of much less importance.

This investigation deals with the temporal aspects of air volume changes during speech. Speech respiration differs fundamentally from resting respiration. In resting respiration the duration and velocity of inspiration (air flow or lung volume change) are in a range similar to that of expiration.

To the Editor.— The letter by Dr Adams on the "respirator brain" and the reply by Dr Walker in the August issue of theArchives(33:589, 1976) indicates the degree to which this subject is plagued by conceptual difficulties. Dr Adams implicates autolytic changes occurring postmortem in the sense of occurring after brain death, while Dr Walker continues ...

Acta Physiologica Scandinavica, 1951
Summary.In the non‐atropinized cat small doses of acetylcholine stimulate respiration practically only by lowering the blood pressure, thereby causing local oxygen want within the carotid and aortic bodies. With somewhat larger doses (0.2 mg) there is also a direct stimulation of the chemoreceptors as well as an inhibition of the centre and a ...

Abstract This outline of the mechanics of breathing is not altogether new and is largely a summary of recent work on the subject from the author's laboratory. The data apply primarily to normal healthy young males and the variations to be expected in other age groups and in clinical practice are still unknown.

Nature, 1968
The qO2 or oxygen uptake of a tissue is considered to be a reflexion of the metabolic energy produced through substrate catabolism to support its functional activities. It is usually accepted that the total in vivo oxygen consumption is directly related to ATP production as the sole energy transfer and storage mechanism for endergonic processes1 ...
