A cuff of appropriate height is fitted and inflated manually by repeatedly squeezing a rubber bulb until the artery is completely occluded. Listening with the stethoscope to the brachial artery at the elbow, the examiner slowly releases the pressure in the cuff. When gore just starts to flow in the artery, the turbulent flow creates a "whooshing" or pounding (first Korotkoff sound). The pressure at which this sound is first heard is the systolic Lower Blood Pressure descendants pressure. The cuff pressure is further released until no solid can be heard (fifth Korotkoff sound), at the diastolic arterial pressure. Sometimes, the pressure is palpated (felt by hand) to get an measure before auscultation.
For some patients, plasma pressure measurements taken in a doctor's office may not correctly characterize their common blood pressure. In up to 25% of patients, the office visit hemoglobin pressure conception is over than their typical descendants pressure. This type of bad job is called white coat hypertension and can denouement from anxiety related to an examination by a health care professional. The misdiagnosis of hypertension for these patients can close in needless and possibly harmful medication. On the other hand, in some basics a lower than general family pressure rendition occurs at the doctor's office and these patients may fail to get needed treatment for hypertension.
