Noninvasive Monitoring of Arterial Pressure: Finger or Lower Leg As Alternatives to the Upper Arm: A Prospective Study in Three ICUs
Authors' conclusion
As compared with lower leg measurements of AP, finger measurements were, when possible, a preferable alternative to upper arm ones.
Study context
- Population
- ICU patients with an arterial catheter and arm circumference <42 cm130 analysed
- Participants
- 130 patients
- Exposure
- Lower leg vs Finger vs Upper
- Outcome
- Agreement for mean AP (bias)

Failure to measure and display arterial pressure (AP)
- Never at other sites
Trending ability after a cardiovascular intervention (concordance rate for change in mean AP, detection of therapy-induced change)
- Good and similar at the three sites
- 33 patients reassessed
