Why the study?
Does a new open-circuit respiratory method accurately and rapidly estimate mixed venous PCO2 in respiratory and cardiac patients?
Does a new open-circuit respiratory method accurately and rapidly estimate mixed venous PCO2 in respiratory and cardiac patients?
A new open-circuit respiratory method rapidly and accurately estimates mixed venous PCO2 in less than 10 seconds, avoiding recirculation artifacts seen with rebreathing techniques.
No takes yet. Share an insight, caveat, or question.
May support rapid noninvasive mixed venous PCO2 estimation in patients; leaves open validation before clinical adoption.
