Why the study?
Does the noninvasive acetylene gas uptake technique accurately measure cardiac output compared to standard invasive thermodilution in ICU and ambulatory patients?
Does the noninvasive acetylene gas uptake technique accurately measure cardiac output compared to standard invasive thermodilution in ICU and ambulatory patients?
The noninvasive acetylene gas uptake technique provides accurate cardiac output measurements that correlate well with invasive thermodilution, and may be more accurate in patients with tricuspid regurgitation.
No takes yet. Share an insight, caveat, or question.
May support noninvasive cardiac output assessment; leaves open prospective validation before clinical adoption.
