This is a nice video about Endotracheal Intubation during a normal surgical practice. Resuscitator Phisician place the endotracheal tube (in particular this is a Combitube). The nurse pump liquid solution into tube’s balloon. Than the phisician makes two ventilations to perform a first control on the correct placement of the Combitube (in lungs, indeed). After this he proceed with auscultation of eventual respiratory noises and respiratory mechanic. After this, nurse provide to link the tube with external ventilator, to obtain an artificial ventilation of the patient. This is a techinque praticated also in Emergency, when you’ve a patient in respiratory arrest (that means a cardiac arrest after fews minutes. be carefull about that!
