The effect of varying inspiratory to expiratory ratio on gas exchange in partial liquid ventilation.

BACKGROUND In partial liquid ventilation (PLV), the nondependent lung was observed to be inflated first and the dependent lung later. The inflational time difference between the lung regions can lead to maldistribution of tidal gas and inefficient gas bubbling in the slow-inflating region during PLV. In this situation, increasing the inspiratory to expiratory (I:E) ratio of the mechanical venti...

The effect of varying inspiratory: expiratory ratios on gas exchange during anaesthesia for open-heart surgery.

Measurements of physiological deadspace/tidal volume ratio (VD/VT per cent) and alveolar-arterial oxygen tension difference (A-aPo2) were made during mechanical ventilation in patients undergoing open-heart surgery. The inspiratory: expiratory time ratios studied were 0.5:2.5 and 1.5:1.5 before perfusion and 0.5:2.5, 1:2 and 1.5:1.5 after perfusion. Pre-perfusion there were no significant diffe...

Influence of inspiratory flow rate upon the effect of a Turbuhaler.

The effect of a new breath actuated dry powder inhaler, the Turbuhaler, was found to be reduced at inhalations slower than 28 1/minute. This flow rate could be generated by virtually all children aged greater than or equal to 6 years, by 42 of 57 children less than 6 years (74%), and by six of 15 preschool children with acute wheeze (40%).
