- Inflate the blood strain cuff to twenty mmHg above the affected person’s systolic blood strain.
- Hear for the Korotkoff sounds utilizing the stethoscope.
- Slowly deflate the cuff whereas listening for the Korotkoff sounds.
- The systolic blood strain is the strain at which the primary Korotkoff sound is heard.
- The diastolic blood strain is the strain at which the final Korotkoff sound is heard.
- File the systolic and diastolic blood strain readings.
- Evaluate the blood strain readings to the aneroid gauge readings.
