Why the study?

Does sitting versus supine position affect blood pressure and heart rate measurements in subjects?

Population

245 subjects (171 hypertensives)

Comparison

Blood pressure measurement in the sitting position vs Blood pressure measurement in the supine position

Design

Cross-sectional, The sequence of the two positions was randomized

Discussion

Member takes

Implication

Diastolic BP and HR differ by posture; supports standardized protocols but should not yet change practice.

Key Points

To determine if blood pressure readings differ when patients are sitting versus supine.
245 subjects measured with both sitting and supine positions using dual devices.
Randomized sequence of measurements repeated for 49 subjects to confirm results.
Averages of three readings compared, analyzing effects of age, BMI, hypertension, and medication.
No influence of posture on systolic blood pressure was found.
Diastolic blood pressure was 5.2 mmHg higher in sitting vs. supine (P<0.001).
Heart rate was also 1.5 beats/min higher in the sitting position (P<0.001).

Structured PICO

Does sitting versus supine position affect blood pressure and heart rate measurements in subjects?

Population

245 subjects (171 hypertensives)

Intervention

Blood pressure measurement in the sitting position

Comparator

Blood pressure measurement in the supine position

Outcome

Difference in systolic and diastolic blood pressure and heart rate between sitting and supine positionssurrogate

Diastolic blood pressure and heart rate are significantly higher when measured in the sitting position compared to the supine position, indicating these measurements are not interchangeable.
