Comparative studies of artificial respiration sets for babies and infants.

In experiments on appropriately modified manikins the action and effectiveness of artificial respiration sets for infants Penlon (British production) and Ambu (Danish production) were compared. The tidal volume, pressure and characteristics of respiratory phases, rebreathing, oxygen concentration, safety systems and their effect on ventilation were assessed. It was found that better ventilation parameters for the needs of resuscitation of newborns and babies can be obtained using the Ambu set, particularly when compliance is lower and bronchial resistance is higher. The Ambu set is simple, easy and safe to use.
