Study Summary

A pulmonary embolism (PE) is a blockage in one of the arteries of the lungs, and is usually caused by a traveling blood clot. The D-dimer blood test is currently used to diagnose PEs, but it is not always accurate for individuals who have recently undergone surgery or who have inflammatory-provoking diseases. The purpose of this study is to evaluate the effectiveness of the Carboximeter, a new PE diagnostic device that measures carbon dioxide (CO2) and oxygen (O2) output, in individuals at risk for developing PEs.

Primary Outcome

Median postoperative change in end tidal CO2/O2 ratio calculated as 100% \* \[(postoperative-preoperative)/(preoperative)\]
