PVC is not radiopaque, and thus a radiopaque linear material is in included throughout the length of the tube to make it easier to visualize the placement on x-ray. This depth provides a baseline measurement to ensure the tube has not traveled out of the trachea or deeper into the trachea with patient movement or transport. After successfully intubating the patient the depth of the endotracheal tube ending at the teeth or lips should be noted. The ETT is measured from the distal end of the tube and is typically marked in 2 cm increments. Medical providers thus should select the largest tube that is appropriate for the patient this is critically important to the spontaneously breathing patient who will have to work harder to overcome the increased resistance (a size 4 ETT has 16 more times resistance to gas flow than a size 8 ETT). The narrower the tube, the greater resistance to gas flow. The ETT will typically list both the inner diameter and outer diameter on the tube (for example, a 6.0 endotracheal tube will list both the internal diameter, ID 6.0, and outer diameter, OD 8.8). The endotracheal tubes size (“give me a 6.0 tube”) refers to its internal diameter in millimeters (mm). The endotracheal tube has a length and diameter. Except for neonatal patients, this practice has largely been discontinued in favor of cuffed pediatric ETT’s. A few well-established criteria are available to aide in ETT size selection. In adults, the narrowest portion of the airway is the vocal cords. Historically, pediatric endotracheal tubes were uncuffed for fear that the pressure from the cuff would damage the trachea via pressure necrosis as the airway just below the vocal cords (cricoid cartilage) is the most narrow part in children.

Pediatric ETT’s are sized by age with options across the spectrum from premature infants to adult size teenage children. For example, ventilator-associated pneumonia (VAP) is a major concern, and the ETT itself is felt to be a primary agent for the development of VAP. Despite advances with the endotracheal tube, more research to optimize its use is necessary. The advancement of the endotracheal tube has closely followed advancements in anesthesia and surgery. Modifications have been made to minimize aspiration, isolate a lung, administer medications, and prevent airway fires. It also serves to protect the lungs from contamination such as gastric contents and blood. In its simplest form, it is a tube constructed of polyvinylchloride (PVC) that is placed between the vocal cords through the trachea to provide oxygen and inhaled gases to the lungs. The endotracheal tube (ETT) was first reliably used in the early 1900s.

This activity describes the indications, contraindications, and techniques involved in endotracheal tube placement and highlights the role of the interprofessional team in the care of patients undergoing this procedure. For example, endotracheal tubes are implicated in the development of ventilator-associated pneumonia, which remains a major concern. Despite these advances, more research to optimize its use is necessary.
