    What will happen to a patient if the positive-pressure-relief (pop-off) valve is accidentally left closed during anesthesia?
    • A. 

      Pressure will build up in the system and the patient will not be able to exhale.

    • B. 

      The lungs will rupture causing a pneumothorax, a life-threatening emergency

    • C. 

      Venous return to the heart will be compromised.

    • D. 

      All of the above.

    • E. 

      A pop-off valve that is accidentally left closed during anesthesia can have catastrophic repercussions. Pressure will build up in the system, and as a result, the patient will not be able to exhale. If pressure continues to build in the thorax, there will be inadequate venous return to the heart. Ultimately, a patient could suffer a ruptured lung and subsequent pneumothorax. Thus, it is EXTREMELY important to remember to open a pop-off valve that has been closed, and always put the anesthetic machine away with the valve in the open position.
