In the newborn, concerning a third of the entirety resistances is positioned at the nose level. As result of Ginevri huge commitment to innovation, Nasal Cannula at Low Resistance has leading a system that is at ease and not traumatic, thanks to its morphology and consistence, and can also be naturally interchanged with a tracheal cannula in ventilation circuits, without causing joined breathing work. The degree of nasal resistances may be increased considerably with the function of cannulas for continuous positive pressure, increasing the patients work of breathing. This may consequence in ipo-ventilation and apnea. Their ambition is to decrease resistances at this level, as a method of counterbalancing the improved work of breathing due to minimization of pulmonary compliance. It is well known that in case of breathing distress, a characteristic symptom is the movement of the nose alae.
