Key result
Fast cuff deflation (>5 mm Hg/sec) significantly underestimated systolic blood pressure by 9 mm Hg (95% CI, -23 to +5 mm Hg; p < 0.001) compared to slow deflation in pregnant and postnatal women.
Why the study?
Accurate blood pressure measurement in pregnancy is critical for diagnosing preeclampsia, but the impact of cuff deflation rate on measurement accuracy and guideline compliance is unclear.
Does fast cuff deflation decrease the accuracy of blood pressure measurement compared to slow deflation in pregnant and postnatal women?
Observational (n=98)
No

Answers are grounded in this paper and cite their sources.
Rapid cuff deflation during blood pressure measurement significantly underestimates systolic blood pressure in pregnant women, emphasizing the importance of adhering to slow deflation guidelines.

Reinders et al. (2006) conducted an observational in Pregnancy (normotensive antenatal or postnatal) (n=98). Fast cuff deflation (>5 mm Hg/sec) vs. Slow cuff deflation (≤2 mm Hg/sec) was evaluated on Systolic blood pressure (MD -9 mm Hg, 95% CI -23 to +5, p=< 0.001). Fast cuff deflation (>5 mm Hg/sec) significantly underestimated systolic blood pressure by 9 mm Hg (95% CI, -23 to +5 mm Hg; p < 0.001) compared to slow deflation in pregnant and postnatal women.
