Is That What You're Calling the End Title CO2?

When we have a patient with intubated, we're seeing an entitled CO2 waveform. If the patient's lungs are relatively normal, that line is going to be pretty flat. And then you have the point where it drops back to the answer zero, which you're calling the end title point. Most people are looking at the waveform qualitatively and looking at the number quantitatively.
