Anesthesia Technologist Practice Exam

What is the primary purpose of a double lumen tube in anesthesia practice?

1. To allow for dual ventilation

2. To facilitate easier intubation

3. To monitor blood pressure

4. To administer anesthetic agents

The correct answer is: To allow for dual ventilation

The primary purpose of a double lumen tube in anesthesia practice is to allow for dual ventilation. This type of endotracheal tube is designed with two separate lumens that can be used to ventilate two different areas of the lungs or to manage both lungs independently, which is particularly useful in cases such as single-lung ventilation during procedures that require isolation of one lung, like thoracotomies. This capability enhances the anesthesiologist's control over ventilation and oxygenation in the patient, enabling more precise management of complex surgical situations. The other options highlight functions that are not the main purpose of a double lumen tube. While facilitating intubation, monitoring blood pressure, and administering anesthetic agents are all important aspects of anesthesia practice, they do not specifically relate to the unique features and intended use of a double lumen tube.
