For safe intubation within seconds, even without a laryngoscope. Resuscitation is guaranteed, whether positioned in the trachea or oesophagus. Over-extending the neck is unnecessary as aspiration of gastric contents is impossible. How to use: Insertion: The COMBITUBUS® is positioned within seconds. The paramedic can stand to the side of the patient and still be able to insert the COMBITUBUS® through the mouth until the 2 black rings are between the lips. Tracheal placement: When auscultation of the lungs is negative, tracheal placement follows. The resuscitation device is connected to the short, transparent connection tube. The COMBITUBUS® now functions as an endotracheal tube.
