Implication

May alter BP values; leaves open whether fixed-stethoscope technique improves reliability before clinical adoption.

Key Points

This research aims to enhance the reliability of blood pressure measurements using a new stethoscope method.
Developed a hand-free stethoscope and method to improve Korotkoff sound interpretation.
Fixed the stethoscope head under the cuff to reduce noise from movement.
Evaluated the device in a sample of 107 patients with blood pressure measurements.
Average systolic blood pressure increased by 3.1 mmHg (p<0.05).
Average diastolic blood pressure decreased by 3.5 mmHg (p<0.05).
The technique significantly improved the differentiation of Korotkoff phases.

Structured PICO

Does a hand-free stethoscope improve the reliability of blood pressure measurements in patients?

Population

107 patients

Intervention

Hand-free stethoscope and hand-free method (stethoscope head fixed under the edge of the cuff)

Comparator

Standard blood pressure measurement method (implied)

Outcome

Systolic and diastolic blood pressure values and distinctness of Korotkoff soundssurrogate

A hand-free stethoscope fixed under the blood pressure cuff reduces noise and provides more distinct Korotkoff sounds, potentially improving the reliability of indirect blood pressure measurements.
