Ventilatory Collapse

Ventilatory drive and ventilatory response during rebreathing.

Maranetra, N. and Pain, M. C. F. (1974). Thorax, 29, 578-581. Ventilatory drive and ventilatory response during rebreathing. The increase in inspiratory airway pressure generated against a transiently occluded airway during rebreathing is proposed as a simple index of ventilatory drive (zlP/dPCO2). A study of this index in 12 normal subjects and 50 patients with chronic airways obstruction demo...

Ventilatory management

All infants at risk of RDS and those with RDS should be closely monitored for clinical and biochemical evidence of respiratory failure. Each unit that undertakes care of such infants should have consultant paediatricians with an up to date knowledge of the principles of mechanical ventilation, who should be responsible for providing a clear respiratory management protocol for all the staff work...

True Collapse and False Collapse

We emphasize that standard quantum theory (SQT) is incomplete because it doesn’t describe what is experimentally observed, namely events, nor does it satisfactorily define the circumstances under which events may occur. Simple models are given (all of which have the same density matrix evolution) to illustrate schemes which claim to complete SQT. It is shown how the model based upon the Continu...

Shock-Induced Bubble Collapse versus Rayleigh Collapse

This paper compares two physical mechanisms for the collapse of a bubble near a rigid wall: a traveling shock-induced collapse and a Rayleigh-like collapse due to a uniform rise of the pressure around the bubble. A multi-material compressible flow solver capable of handling material interfaces under high pressures is used to investigate these two scenarios for different levels of the driving pr...
