Podcast 889: Blood Pressure Cuff Size
Manage episode 399337557 series 1397179
Contributor: Aaron Lessen MD
Educational Pearls:
Does the size of a blood pressure (BP) cuff matter?
A recent randomized crossover trial revealed that, indeed, cuff size can affect blood pressure readings
Design
195 adults with varying mid-upper arm circumferences were randomized to the order of BP cuff application:
Appropriate
Too small
Too large
Individuals had their mid-upper arm circumference measured to determine the appropriate cuff size
Participants underwent 4 sets of triplicate blood pressure measurements, the last of which was always with the appropriately sized cuff
Results
In individuals requiring a small cuff, the use of a regular cuff resulted in blood pressure readings 3.6 mm Hg lower than with the small cuff
In individuals requiring large cuffs, the use of a regular cuff resulted in pressures 4.8 mm Hg higher than with the large cuffs
In individuals requiring extra-large cuffs, the use of a regular cuff resulted in pressures 19.5 mm Hg higher than with extra-large cuffs
Conclusion
Miscuffing results in significantly inaccurate blood pressure measurements
It is important to emphasize individualized BP cuff selection
