Evaluation of deadspace effects created by heat and moisture exchange filter during artificial lung ventilation in newborns

Heat and moisture exchange filters create additional dead space, comparable in volume to physiological, premature newborns. It makes carbon dioxide remove difficultу. Reducing the space by increasing flow ventilator circuit can lead hypocapnia. Aim of study was determine safety efficiency gas boost hypercapnia compensation created space. Material methods. The effect a heat filter on hemoglobin saturation partial pressure at end expiration newborns flows 5 6 l/min studied. Results discussion. has been demonstrated that 5–6 satisfactorily compensate for deadspace without Conclusions. is possible recommend widespread use newborn weighing least 1.0 kg during long-term transportation.
