You are ventilating an intubated patient who suffered multisystem trauma. While the paramedic with whom you are working is starting an IV, you both glance at the capnometer device and see that the numeric display is dropping quickly. If there has been no change in ventilatory rate or depth, what could be another cause for this end-tidal carbon dioxide change?

Question

Quizplus · Accepted Answer

A drop in end-tidal carbon dioxide could indicate a decrease in blood flow to the lungs, which could be caused by factors such as low cardiac output or obstruction in the pulmonary vasculature. It is important to investigate and address this issue as it can indicate poor perfusion and lead to further deterioration in the patient's condition. The other options provided (B, C, and D) are not likely causes for a rapid drop in end-tidal carbon dioxide.
