Effects of Cuff Size on the Accuracy of Blood Pressure Readings: The Cuff(SZ) Randomized Crossover Trial
Authors' conclusion
In this randomized crossover trial, miscuffing resulted in strikingly inaccurate BP measurements.
Study context
- Population
- Community-dwelling adults with a wide range of mid-arm circumferences, Baltimore, Maryland, 2021randomized
- Participants
- 195 adults
- Comparison
- Regular blood pressure (BP) cuff vs appropriately sized BP cuff
- Primary endpoint
- Difference in mean BP with a regular vs an appropriate BP cuff
Primary result
As reported in the abstract
Mean SBP difference, regular vs appropriate cuff, by required cuff size
Regular BP cuff vs Appropriate BP cuffMean systolic BP difference, mm Hg (95% CI)
Requiring small cuff
−3.6(−5.6 to −1.7)
Requiring large cuff
4.8(3.0–6.6)
Requiring extra-large cuff
19.5(16.1–22.9)
Secondary outcomes
BP difference with too-small or too-large vs appropriate cuff
- BP differences with overcuffing and undercuffing by 1 and 2 cuff sizes greater among those requiring larger cuffs
Stratified by SBP (≥130 vs <130 mm Hg) and BMI (≥30 vs <30)
- Results consistent in stratified analyses
