More Information
Summary:The endotracheal respiration system minimises unused capacity in the lung; by having exhalation and inhalation lines which are separate in the endotracheal tube right up until they discharge into the trachea. Pref. a gas flow in a third line compensates for effective tube resistance from spontaneous exhalation. A connected circulatory system supplies fresh gas into the inhalation tube between the tube and the valve. The gas flow in the third line also builds up a pressure wave directly in front of the lungs during inhalation, so that combined with the exhalation resistance compensation the lungs can be more rapidly emptied. The system is especially designed for babies and small children.
