Multimodal Noninvasive Monitoring of Arterial Pressure: Do Limitations of Finger Cuff Monitoring Compromise Upper Arm Measurements? A Post Hoc Analysis of Two Prospective Cohorts
Authors' conclusion
When unreliable or unavailable, cuff ARM provides reliable measurements, effectively detects hypotension and hypertension, and poses no significant risk to the patient.
Study context
- Population
- ICU adults with an arterial catheter and stable arterial pressure (AP)214 CNAP, 138 ClearSight
- Participants
- 352 adults
- Comparison
- Oscillometric upper arm cuff (cuffARM) vs finger cuff (cuffFINGER: CNAP, ClearSight), arterial catheter as reference
Methodological detailsthree ICUs, reference: arterial catheter
- Three ICUs
- Reference: arterial catheter
Primary result
As reported in the abstract
Mean AP reliability in patients with poor fingertip perfusion (capillary refill time >4 s) and/or hand edema (n = 102, 29%)
| Group | Value | Measurements (n) | No or low risk of harm | AUC hypotension (95% CI 0.87-0.94) | AUC hypertension (95% CI 0.75-1) |
|---|---|---|---|---|---|
| Cuff | bias 2.2 (SD 7.2) mm Hg | 304 | 99.7% | 0.91 | 0.92 |
| Cuff FINGER | 17% |

Further findings
- Mean AP reliability of cuff ARM when cuff FINGER failed to display AP (38 of 352 patients, 11%) — cuff
- bias 1.7 (SD 7.1) mm Hg
Mean AP reliability of cuff ARM when cuff FINGER failed to display AP (38 of 352 patients, 11%)
- Cuff ARM met ISO 81060-2:2018 standard for mean AP
Mean AP without failure or risk factors for erroneous measurements
- ClearSight met ISO 81060-2:2018 standard for mean AP, unlike the CNAP system
