II. Preparation: Positioning of Blood Pressure Cuff
- Cuff applied directly over skin (not through clothes)
- Clothes artificially raises Blood Pressure
- Center inflatable Bladder over brachial artery
- Position lower cuff border 2.5 cm above antecubital
- Patient's arm slightly flexed at elbow
- Position stethoscope bell over brachial artery
III. Equipment: Blood Pressure cuff size
- Poor cuff fit results in inaccurate Blood Pressure
- Undersized cuff artificially raises Blood Pressure
- Oversized cuff artificially lowers Blood Pressure
- Pediatric Cuff size
- Adult Cuff size
IV. Technique: BP measurement
- Wait 5 minutes of rest before checking Blood Pressure
- Check Blood Pressure in right arm, while seated
- Take Blood Pressure at heart level
- Inflate cuff rapidly to level above suspected SBP
- Deflate cuff slowly at a rate of 2-3 mmHg per second
- Listen for auditory vibrations from artery (Korotkoff)
- Systolic Blood Pressure: Onset of consecutive sounds
- Diastolic Blood Pressure: Disappearance of sounds
V. Technique: Obtain Multiple Blood Pressure measurements
- Validation of abnormal readings
- Recheck Blood Pressure twice more at same visit
-
Aortic Coarctation
- Left and right arm, and one lower extremity
-
Orthostatic Hypotension
- Check Blood Pressure and Pulse, Supine and Standing
VI. Interpretation
- See Hypertension Criteria
- See Hypotension
VII. Interpretation: Children
- See Pediatric Vital Signs

| Definition (MSHCZE) | Zkr. TK – tlak, kterým krev působà na stÄ›nu cév, zejm. tepen. Zdrojem TK je Ä�innost srdce Ä�erpajÃcÃho krev do aorty, která sloužà jako pružný rezervoár krve. TK v průbÄ›hu srdeÄ�nÃho cyklu (systoly a diastoly) stoupá a klesá, nejvyššà hodnoty dosahuje v systole (systolický t.), kdy je také objem krve v aortÄ› nejvÄ›tÅ¡Ã. (cit.

| Definition (NCI_NCI-GLOSS) | The force of circulating blood on the walls of the arteries. Blood pressure is taken using two measurements: systolic (measured when the heart beats, when blood pressure is at its highest) and diastolic (measured between heart beats, when blood pressure is at its lowest). Blood pressure is written with the systolic blood pressure first, followed by the diastolic blood pressure (for example 120/80). |
| Definition (NCI) | The pressure of the circulating blood against the walls of the blood vessels. |
| Definition (MSH) | PRESSURE of the BLOOD on the ARTERIES and other BLOOD VESSELS. |
| Definition (CSP) | force exerted by the blood on the walls of the arteries and other vessels. |
