In the condition of any obstruction in the airway, endotracheal tubes are used to deliver air to the lungs. Endotracheal tubes are polymeric catheters made of heat-sensitive polymers like PVC to have the most conformity with the respiratory system. The tubing is done via nose or mouth into the tracheal and can even assist the drug delivery. Endotracheal tubes are often used up for air management goals and make an artificial respiratory airway. NilooMedica Corporation manufactures Endotracheal Tubes with murphy eye, a substitute airway, and cuff, a balloon placed at the end of the tube that inflates in the tubing location to fix the Endotracheal Tube. The importance of the cuff is that it also prevents any leakage of respiratory gas and blocks the entrance of undesirable stomach acid. Endotracheal Tubes are equipped with the required fixtures for their connection to the oxygen tank. Endotracheal Tubes with/without cuffs (for children) are ready to order and they are available in sizes of 2-10.5 mm in internal diameter.
