Volume guarantee ventilation, interrupted expiration, and expiratory braking.

BACKGROUND In volume guarantee ventilation with the Dräger Babylog 8000 ventilator, inspiratory and expiratory flows are monitored and the expiratory tidal volume calculated following each inflation. The pressure for the next inflation is modified to ensure the expired tidal volume is close to the set value. AIM To investigate interrupted expiration observed during volume guarantee ventilatio...

Prolonged slow expiration technique in infants: effects on tidal volume, peak expiratory flow, and expiratory reserve volume.

BACKGROUND Prolonged slow expiration (PSE) is a physiotherapy technique often applied in infants to reduce pulmonary obstruction and clear secretions, but there have been few studies of PSE's effects on the respiratory system. OBJECTIVE To describe PSE's effects on respiratory mechanics in infants. METHODS We conducted a cross-sectional study with 18 infants who had histories of recurrent ...

Neonatal volume guarantee ventilation: effects of spontaneous breathing, triggered and untriggered inflations.

BACKGROUND During volume guarantee (VG) ventilation the peak inflating pressure (PIP) for each ventilator inflation is adjusted to ensure the expired tidal volume (V(Te)) is close to the set V(Te). Differences in the PIP between inflations triggered by the infant's inspirations and untriggered inflations are seen. AIM To investigate the effects of triggered and untriggered inflations on PIP a...

Ventilation through a small-bore catheter: optimizing expiratory ventilation assistance.

BACKGROUND Emergency ventilation through a small-bore transtracheal catheter can be lifesaving in a 'cannot intubate, cannot ventilate' situation. Ejectors, capable of creating suction by the Bernoulli principle, have been proposed to facilitate expiration through small-bore catheters. In this bench study, we compared a novel, purpose-built ventilation ejector (DE 5) with a previously proposed,...

Influence of end-expiratory lung volume on carbon dioxide elimination during high frequency ventilation in dogs.

We have examined the effect of varying end-expiratory lung volume on carbon dioxide elimination in 10 mongrel dogs undergoing conventional mechanical ventilation at 12 b.p.m. and forced diffusion ventilation (FDV) at 6 Hz and 50 Hz and continuous flow. End-expiratory volumes were altered by changing the pressure in a plethysmographic box in which the dogs underwent ventilation. The pressures st...
