These devices have an aneroid gauge that consists of metal bellows with a watch-like movement connected to a compression cuff. Included in the SP10 standard are automated NIBP monitors which measure blood pressure at the arm, wrist, or finger of the patient using a standard oscillometric measurement method . The morning BP surge has been defined as the difference between the average BP during the 2 hours after awakening and either the mean during the 2 hours before awakening or the mean of the lowest nighttime BP and the 2 readings surrounding the lowest reading. A pharmacist-led, American Heart Association Heart360 Web-enabled home blood pressure monitoring program. When BP measurements are taken in the supine position, the cuffed arm should be supported with a pillow. The wrist must be kept at heart level to obtain an accurate reading. Ambulatory monitoring is mainly used for diagnosing hypertension, whereas self-monitoring is used for following the response to treatment. In the office setting, BP should be measured in duplicate while the patient is seated, in the standing position immediately after rising, and again after 1 to 2 minutes to assess for potential postural hypotension. 1 The diagnosis and management of hypertension depend on the accurate measurement of BP. Human Errors in Automated Office Blood Pressure Measurement Ambulatory monitoring of blood pressure: an overview of devices, analyses, and clinical utility. If using the auscultatory technique, record SBP and DBP as the onset of the first of at least 2 consecutive beats and the last audible sound, respectively.

A new international universal validation protocol (Association for the Advancement of Medical Instrumentation/ESH/International Organization for Standardization) is being developed that may become the new standard for device validation.24 Separate device validation studies should be performed in special populations, including children, pregnant women, and patients with AF and large arm circumferences (>42 cm).24, Table 12. The sequence of sounds is as follows: phase 1, sudden appearance of sharp tapping sounds, considered to be SBP; phase 2, swishing sounds; phase 3, regular, louder sounds; phase 4, abrupt muffling of sounds; and phase 5, loss of all sounds, considered to be DBP.25,27,28, The auscultatory method using a mercury sphygmomanometer has been the reference standard for office BP measurement for several decades.

Kiosks are stations where BP is assessed by a device that is triggered by the individual desiring the measurement in the absence of a healthcare professional.245 Kiosk measurements, which are a form of self-measured BP, can be useful, especially for BP screening, as long as the device is appropriately validated and calibrated. Note the time that the most recent BP medication was taken before measurements. Packed with practical guidance in an easy-to-use format, this book is ideally suited for quick access in emergency rooms or intensive care units. Inflate the cuff 20–30 mm Hg above this level for an auscultatory determination of the BP level. 2011 Nov;24(11):1201-8. doi: 10.1038/ajh.2011.125.

Self-monitoring is growing rapidly in popularity and is generally carried out using electronic devices that work on the oscillometric technique. Self-monitoring of blood pressure at home: how many measurements are needed? Routine office BP measurements obtained in clinical practice with the auscultatory method demonstrate substantial variability. How to play a vital role in your own health and longevity: A handbook from“one of the most reliable, respected health resources that Americans have” (Publishers Weekly). Recommendations for blood pressure measurement in humans and experimental animals: Part 1: blood pressure measurement in humans: a statement for professionals from the Subcommittee of Professional and Public Education of the American Heart Association Council on High Blood Pressure Research.

A systematic review of the effects of home blood pressure monitoring on medication adherence. The validation protocol of the Association for the Advancement of Medical Instrumentation is less complex than the British Hypertension Society protocol but requires a similar sample size and participants with a wide range of BP and asks for specific assessment for special populations. Similar to ABPM, HBPM can be used to identify white-coat hypertension, white-coat effect, masked hypertension, and masked uncontrolled hypertension, phenotypes described in the White-Coat Hypertension and White-Coat Effect section and the Masked Hypertension section. A list of validated HBPM devices can be found on the British and Irish Hypertension Society and Dabl Educational Trust websites.174a,174b. Comparison of oscillometric and intraarterial systolic and diastolic blood pressures in lean, overweight, and obese patients. The validity of blood pressure kiosk validation studies: a systematic review. ABPM is the primary method to detect this phenotype. Reproducibility of blood pressure dipping: relation to day-to-day variability in sleep quality. The last scientific statement from the AHA on BP measurement in humans was published in 2005.5 There have been a number of studies that inform the approaches to BP measurement since the 2005 AHA BP measurement scientific statement was published. Table 11. Reproducibility of masked hypertension among adults 30 years or older. From Korotkoff and Marey to automatic non-invasive oscillometric blood pressure measurement: does easiness come with reliability? If elevated BP is present when measured with an oscillometric device, auscultation should be performed to define BP categories. Automated oscillometric blood pressure versus auscultatory blood pressure as a predictor of carotid intima-medial thickness in male firefighters. In addition, the US Preventive Services Task Force and the 2017 Hypertension Clinical Practice Guidelines recommend confirmation of office BPs by ABPM or home BP monitoring (HBPM) for the initial diagnosis of hypertension and BP control (see the Twenty-Four–Hour ABPM and the Home BP Monitoring sections). The American Heart Association makes every effort to avoid any actual or potential conflicts of interest that may arise as a result of an outside relationship or a personal, professional, or business interest of a member of the writing panel.

Characterization of the oscillometric method for measuring indirect blood pressure. Comparison of an in-pharmacy automated blood pressure kiosk to daytime ambulatory blood pressure in hypertensive subjects. BLOOD pressure (BP) is routinely checked intermittently during the perioperative care of patients.‡‡The most common method to measure BP uses the oscillometric principle that consists of the application of an upper arm cuff, which is automatically inflated and deflated to yield a numeric display of systolic, diastolic, and mean BPs. Customer Service Stroke prognosis and abnormal nocturnal blood pressure falls in older hypertensives. Comparability of automated office blood pressure to daytime 24-hour ambulatory blood pressure. A cuff is placed around the finger and inflated to a pressure equal to the pressure in the artery until the artery is about to collapse and the transmural pressure is almost at zero. Ambulatory blood pressure in normotensive and hypertensive subjects: results from an international database. In addition, a leg BP should be obtained while the patient is supine for all hypertensive pediatric patients to rule out coarctation of the aorta.250 If the leg BP values are >10 mm Hg lower than the arm BP, additional investigation is warranted. ABPM may be useful in identifying white-coat hypertension, hypotension in the postprandial state, and after awakening in the morning. Compared with their counterparts with sustained normotension (ie, nonhypertensive BP levels in and outside the office setting), it is unclear whether adults with white-coat hypertension (ie, hypertensive BP levels in the office but not outside the office) have increased cardiovascular disease risk, whereas those with masked hypertension (ie, hypertensive BP levels outside the office but not in the office) are at substantially increased risk. The classification, diagnosis and management of the hypertensive disorders of pregnancy: a revised statement from the ISSHP.
