Testing a breathing gas measurement to assess severe COPD attacks

Researchers are testing whether measuring a specific gas in your breath — called end-tidal carbon dioxide — can help doctors better understand how serious your COPD attack is when you arrive at the emergency department. Right now, doctors use other vital signs to decide how sick you are. This study wants to see if this breathing measurement provides useful extra information to guide your care.

During a COPD attack, doctors need quick, accurate ways to figure out how serious the situation is so they can give the right level of treatment. This breathing measurement might help spot patients who are in more danger and need more intensive care.
