  1. ENDOTRACHEAL TUBE (ETT) Dr . Rupak Bhattarai Taishan Medical University

  2. INTRODUCTION Tracheal tube can be used to deliver anesthetic gases directly into the trachea and allow the most control of ventilation and oxygenation. Tracheal tubes are most commonly made up of polyvinyl chloride. The shape and rigidity of TT’s can be altered by inserting a stylet.

  3. PARTS OF ETT It consists of the following parts : • BEVELED TIP • MURPHY EYE • CUFF • CONNECTOR • PILOT BALLOON • VALVE

  5. DIFFERENT SIZES ENDOTRACHEAL TUBES

  6. The BEVELED TIP aid visualisation and insertion through the vocal cords. MURPHY EYE is a hole to decrease the risk of occlusion. CUFF reduces the likelihood of aspiration. The INFLATING TUBE connects the valve to the cuff through the Endotracheal tubes. The PILOT BALLOON provides the gross indication of cuff inflation. The VALVE prevents air loss after cuff has been inflated.

  7. ORAL TRACHEAL TUBE SIZE GUIDELINES FULL TERM INFANT : 3.5 mm CHILD : 4+age /4 (mm) ADULT : FEMALE : 7.0-7.5 (mm) MALE : 7.5-9.0 (mm)
