Why the study?
When the upper arm is inaccessible for arterial pressure measurements, the best alternative site is unknown.
Does noninvasive arterial pressure measurement at the finger or lower leg provide comparable agreement to invasive measurements as the upper arm in ICU patients?
Does noninvasive arterial pressure measurement at the finger or lower leg provide comparable agreement to invasive measurements as the upper arm in ICU patients?
Finger cuff measurements of arterial pressure provide a reliable alternative to upper arm measurements in ICU patients, whereas lower leg measurements are less accurate and not recommended.
Finger cuff may be preferable to lower leg for noninvasive AP when arm inaccessible in ICU; leaves open need for randomized validation before practice change.
