![]() ![]() Malpositioned ET tubeĪdvancement of ET tube inferiorly into the bronchus may result in hyperinflation of the intubated lung and collapse of the contralateral lung. Accounting for flexion and extension of neck, a 2 cm ascend or descend from the aforementioned measurements is commonly encountered. Preferably, the ET tube is positioned in the mid-thoracic trachea terminating 3–5 cm from above the carina. The normal position of the carina is at the level of T4-T5 which is used as the landmark for ET tube positioning. The normal positioning of the endotracheal tube is always referred to as the distance of the ET tube tip from the carina. Positioning of endotracheal tube: Always start with ensuring the ET tube is within the tracheal air column. The parts of the ET tube include an inflatable cuff that will safely secure the trachea to avert air leak and decrease the risk of aspiration. ENDOTRACHEAL TUBEĪ diverse variety of endotracheal tubes is in clinical practice. However, radiographs are recommended whenever there is a significant change in clinical status, placement and repositioning of support devices, and after any bedside procedures. According to a recent American College of Radiology appropriateness criteria, there is no specific necessity to obtain daily routine chest radiographs. Due to the complexity of the critically ill patients in intensive care units, the performance of daily routine radiographs has been in practice for decades. Chest radiograph is the most performed radiographic examination because of the simplicity in the technique and its clinical utility in both inpatient and outpatient settings. ![]()
