Measuring Blood Pressure: Correct Techniques and Misconceptions

Correct Techniques for Measuring Blood Pressure:

1. Positioning: The patient's forearm should be supported on a flat surface to ensure accuracy in blood pressure measurement.

2. Sphygmomanometer Cuff Placement: The lower edge of the cuff should be positioned 1 to 1 1/2 inches below the antecubital area for optimal results.

3. Bladder Length: The bladder on the cuff should approximately cover 80 percent of the circumference of the patient's upper arm.

4. Arm Clothing: While it is recommended to have the arm free of constrictive clothing and the cuff applied to bare skin for best results, blood pressure can also be measured over light garments like t-shirts.

By following these correct techniques, healthcare professionals can obtain accurate blood pressure readings.
