Why the study?
Does ankle blood pressure measurement significantly differ from upper arm blood pressure measurement at different backrest elevations in medical ICU patients?
Does ankle blood pressure measurement significantly differ from upper arm blood pressure measurement at different backrest elevations in medical ICU patients?
Ankle blood pressures are significantly greater than arm blood pressures and should not be considered interchangeable in critical care settings.
No takes yet. Share an insight, caveat, or question.
Ankle-arm systolic BP differences at 0°/30° elevations may limit interchangeability in ICU patients; hypothesis-generating and leaves clinical impact open.
Henley et al. (2015) studied this question.
